Sino-Japanese War (1937-1945)

11.1 Chinese
Soviet Union and the United States. After the Japanese attacks on Malaya and Pearl Harbor in 1941, the war merged with other conflicts which are generally categorized under those conflicts of World War II as a major sector known as the China Burma India Theater. Some scholars consider the European War and the Pacific War to be entirely separate, albeit concurrent, wars. Other scholars consider the start of the full-scale Second Sino-Japanese War in 1937 to have been the beginning of World War II.^[29]^[30] The Second Sino-Japanese War was the largest Asian war in the 20th century.^[31] It accounted for the majority of civilian and military casualties in the Pacific War, with between 10 and 25 million Chinese civilians and over 4 million Chinese and Japanese military personnel missing or dying from war-related violence, famine, and other causes. The war has been called "the Asian holocaust."^[32]
The war was the result of a decades-long Japanese imperialist policy to expand its influence politically and militarily in order to secure access to raw material reserves, food, and labor. The period after World War I brought about increasing stress on the Japanese polity. Leftists sought universal suffrage and greater rights for workers. Increasing textile production from Chinese mills was adversely affecting Japanese production and the Great Depression brought about a large slowdown in exports. All of this contributed to militant nationalism, culminating in the rise to power of a militarist faction. This faction was led at its height by the Hideki Tojo cabinet of the Imperial Rule Assistance Association under edict from Emperor Hirohito. In 1931, the Mukden Incident helped spark the Japanese invasion of Manchuria. The Chinese were defeated and Japan created a new puppet state, Manchukuo; many historians cite 1931 as the beginning of the war.^[33]^[34] This view has been adopted by the PRC government. From 1931 to 1937, China and Japan continued to skirmish in small, localized engagements, so-called "incidents".
Following the Marco Polo Bridge Incident, the Japanese scored major victories, capturing Beijing, Shanghai and the Chinese capital of Nanjing in 1937, which resulted in the Rape of Nanjing. After failing to stop the Japanese in the Battle of Wuhan, the Chinese central government was relocated to Chongqing (Chungking) in the Chinese interior. With the strong material support through the Sino-Soviet Treaty of 1937, the Nationalist Army of China and the Chinese Air Force were able to continue putting up strong resistance against the Japanese offensive. By 1939, after Chinese victories in Changsha and Guangxi, and with Japan's lines of communications stretched deep into the Chinese interior, the war reached a stalemate. While the Japanese were also unable to defeat the Chinese communist forces in Shaanxi, who waged a campaign of sabotage and guerrilla warfare against the invaders, they ultimately succeeded in the year-long Battle of South Guangxi to occupy Nanning, which cut off the last sea access to the wartime capital of Chongqing. While Japan ruled the large cities, they lacked sufficient manpower to control China's vast countryside. In November 1939, Chinese nationalist forces launched a large scale winter offensive, while in August 1940, Chinese communist forces launched a counteroffensive in central China. The United States supported China through a series of increasing boycotts against Japan, culminating with cutting off steel and petrol exports into Japan by June 1941.^[35] Additionally, American mercenaries such as the Flying Tigers provided extra support to China directly.
In December 1941, Japan launched a surprise attack on Pearl Harbor, and declared war on the United States. The United States declared war in turn and increased its flow of aid to China – with the Lend-Lease act, the United States gave China a total of $1.6 billion ($18.4 billion adjusted for inflation).^[36] With Burma cut off it airlifted material over the Himalayas. In 1944, Japan launched Operation Ichi-Go, the invasion of Henan and Changsha. However, this failed to bring about the surrender of Chinese forces. In 1945, the Chinese Expeditionary Force resumed its advance in Burma and completed the Ledo Road linking India to China. At the same time, China launched large counteroffensives in South China and retook West Hunan and Guangxi. Japan formally surrendered on 2 September 1945. China regained all territories lost to Japan.
In China, the war is most commonly known as the "War of Resistance against Japanese Aggression" (simplified Chinese: 抗日战争; traditional Chinese: 抗日戰爭), and shortened to the "Resistance against Japanese Aggression" (Chinese: 抗日) or the "War of Resistance" (simplified Chinese: 抗战; traditional Chinese: 抗戰). It was also called the "Eight Years' War of Resistance" (simplified Chinese: 八年抗战; traditional Chinese: 八年抗戰), but in 2017 the Chinese Ministry of Education issued a directive stating that textbooks were to refer to the war as the "Fourteen Years' War of Resistance" (simplified Chinese: 十四年抗战; traditional Chinese: 十四年抗戰), reflecting a focus on the broader conflict with Japan going back to 1931.^[37] It is also referred to as part of the "Global Anti-Fascist War", which is how World War II is perceived by the Communist Party of China and the PRC government.^[38]
In Japan, nowadays, the name "Japan–China War" (Japanese: 日中戦爭, romanized: Nitchū Sensō) is most commonly used because of its perceived objectivity. When the invasion of China proper began in earnest in July 1937 near Beijing, the government of Japan used "The North China Incident" (Japanese: 北支事變/華北事變, romanized: Hokushi Jihen/Kahoku Jihen), and with the outbreak of the Battle of Shanghai the following month, it was changed to "The China Incident" (Japanese: 支那事變, romanized: Shina Jihen).
The word "incident" (Japanese: 事變, romanized: jihen) was used by Japan, as neither country had made a formal declaration of war. From the Japanese perspective, localizing these conflicts was beneficial in preventing intervention from other nations, particularly the United Kingdom and the United States, which were its primary source of petroleum and steel respectively. A formal expression of these conflicts would potentially lead to American embargo in accordance with the Neutrality Acts of the 1930s.^[39] In addition, due to China's fractured political status, Japan often claimed that China was no longer a recognizable political entity on which war could be declared.^[40]

Other names

In Japanese propaganda, the invasion of China became a crusade (Japanese: 聖戦, romanized: seisen), the first step of the "eight corners of the world under one roof" slogan (Japanese: 八紘一宇, romanized: Hakkō ichiu). In 1940, Japanese Prime Minister Fumimaro Konoe launched the Taisei Yokusankai. When both sides formally declared war in December 1941, the name was replaced by "Greater East Asia War" (Japanese: 大東亞戰爭, romanized: Daitōa Sensō).
Although the Japanese government still uses the term "China Incident" in formal documents,^[41] the word Shina is considered derogatory by China and therefore the media in Japan often paraphrase with other expressions like "The Japan–China Incident" (Japanese: 日華事變/日支事變, romanized: Nikka Jiken/Nisshi Jiken), which were used by media as early as the 1930's.
The name "Second Sino-Japanese War" is not commonly used in Japan as the war it fought with the Qing dynasty in 1894 is called the Qing-Japanese War (Japanese: 日清戦争, romanized: Nisshin–Sensō) rather than the First Sino-Japanese War.

Historical background

The origins of the Second Sino-Japanese War can be traced back to the First Sino-Japanese War of 1894–1895, in which China, then under the rule of the Qing dynasty, was defeated by Japan, forced to cede Taiwan to Japan, and recognize the full and complete independence of Korea in the Treaty of Shimonoseki; Japan also annexed the Diaoyudao/Senkaku Islands in early 1895 as a result of its victory at the end of the war (Japan claims the islands were uninhabited in 1895).^[42]^[43]^[44] The Qing dynasty was on the brink of collapse due to internal revolts and foreign imperialism, while Japan had emerged as a great power through its effective measures of modernization.^[45]

Republic of China

The Republic of China was founded in 1912, following the Xinhai Revolution which overthrew the last imperial dynasty of China, the Qing dynasty (1644–1911). However, central authority disintegrated and the Republic's authority succumbed to that of regional warlords, mostly from the former Beiyang Army. Unifying the nation and repelling imperialism seemed a very remote possibility.^[46] Some warlords even aligned themselves with various foreign powers in their battles with each other. For example, the warlord Zhang Zuolin of Manchuria from the Fengtian clique openly cooperated with the Japanese for military and economic assistance.^[47]

Twenty-One Demands

In 1915, Japan issued the Twenty-One Demands to extort further political and commercial privilege from China, which was accepted by Yuan Shikai.^[48] Following World War I, Japan acquired the German Empire's sphere of influence in Shandong province,^[49] leading to nationwide anti-Japanese protests and mass demonstrations in China. Under the Beiyang Government, China remained fragmented and was unable to resist foreign incursions.^[50] For the purpose of unifying China and defeating the regional warlords, the Kuomintang (KMT, alternatively known as the Chinese Nationalist Party) in Guangzhou launched the Northern Expedition from 1926 to 1928 with limited assistance from the Soviet Union.^[51]

Jinan incident

Main article: Jinan incident

The National Revolutionary Army (NRA) formed by the KMT swept through southern and central China until it was checked in Shandong, where confrontations with the Japanese garrison escalated into armed conflict. The conflicts were collectively known as the Jinan incident of 1928, during which time the Japanese military killed several Chinese officials and fired artillery shells into Jinan. Between 2,000 and 11,000 Chinese and Japanese civilians were believed to have been killed during these conflicts. Relations between the Chinese Nationalist government and Japan severely worsened as a result of the Jinan incident.^[52]^[53]

As the National Revolutionary Army approached Beijing, Zhang Zuolin decided to retreat back to Manchuria, before he was assassinated by the Kwantung Army in 1928.^[54] His son, Zhang Xueliang, took over as the leader of the Fengtian clique in Manchuria. Later in the same year, Zhang decided to declare his allegiance to the Nationalist government in Nanjing under Chiang Kai-shek, and consequently, China was nominally reunified under one government.^[55]

1929 Sino-Soviet war

Main article: Sino-Soviet conflict (1929)

The July–November 1929 conflict over the Chinese Eastern Railroad (CER) further increased the tensions in the Northeast that led to the Mukden Incident and eventually the Second Sino-Japanese War. The Soviet Red Army victory over Zhang Xueliang's forces not only reasserted Soviet control over the CER in Manchuria but revealed Chinese military weaknesses that Japanese Kwantung Army officers were quick to note.^[56]
The Soviet Red Army performance also stunned the Japanese. Manchuria was central to Japan's East Asia policy. Both the 1921 and 1927 Imperial Eastern Region Conferences reconfirmed Japan's commitment to be the dominant power in the Northeast. The 1929 Red Army victory shook that policy to the core and reopened the Manchurian problem. By 1930, the Kwantung Army realized they faced a Red Army that was only growing stronger. The time to act was drawing near and Japanese plans to conquer the Northeast were accelerated.^{Japanese: 日中戦爭, romanized: Nitchū Sensō) is most commonly used because of its perceived objectivity.

In 1930, the Central Plains War broke out across China, involving regional commanders who had fought in alliance with the Kuomintang during the Northern Expedition, and the Nanjing government under Chiang. The Communist Party of China (CPC) previously fought openly against the Nanjing government after the Shanghai massacre of 1927, and they continued to expand during this civil war. The Kuomintang government in Nanjing decided to focus their efforts on suppressing the Chinese Communists through the Encirclement Campaigns, following the policy of "first internal pacification, then external resistance" (Chinese: 攘外必先安內).

Prelude: invasion of Manchuria and Northern China

Main article: Battle of Shanghai

Japanese landing near Shanghai, November 1937

The Imperial General Headquarters (GHQ) in Tokyo, content with the gains acquired in northern China following the Marco Polo Bridge Incident, initially showed reluctance to escalate the conflict into full-scale war. The KMT, however, determined that the "breaking point" of Japanese aggression had been reached. Chiang Kai-shek quickly mobilized the central government's army and Imperial General Headquarters (GHQ) in Tokyo, content with the gains acquired in northern China following the Marco Polo Bridge Incident, initially showed reluctance to escalate the conflict into full-scale war. The KMT, however, determined that the "breaking point" of Japanese aggression had been reached. Chiang Kai-shek quickly mobilized the central government's army and air force, placed them under his direct command, and laid siege to the Japanese area of Shanghai International Settlement, where 30,000 Japanese civilians lived with 30,000 troops on 12 August 1937.

On 13 August 1937, Kuomintang soldiers and warplanes attacked Japanese Marine positions in Shanghai, leading to the Battle of Shanghai. On 14 August, Kuomintang planes accidentally bombed the Kuomintang soldiers and warplanes attacked Japanese Marine positions in Shanghai, leading to the Battle of Shanghai. On 14 August, Kuomintang planes accidentally bombed the Shanghai International Settlement, which led to more than 3,000 civilian deaths.^[59] In the three days from 14 August through 16, 1937, the Imperial Japanese Navy (IJN) sent many sorties of the then-advanced long-ranged G3M medium-heavy land-based bombers and assorted carrier-based aircraft with the expectation of destroying the Chinese Air Force. However, the Imperial Japanese Navy encountered unexpected resistance from the defending Chinese Curtiss Hawk II/Hawk III and P-26/281 Peashooter fighter squadrons; suffering heavy (50%) losses from the defending Chinese pilots (14 August was subsequently commemorated by the KMT as China's Air Force Day).^[60]^[61]

The skies of China had become a testing zone for advanced biplane and new-generation monoplane combat-aircraft designs. The introduction of the advanced A5M "Claude" fighters into the Shanghai-Nanjing theater of operations, beginning on 18 September 1937, helped the Japanese achieve a certain level of air superiority.^[62]^[63] However the few experienced Chinese veteran pilots, as well as several Chinese-American volunteer fighter pilots, including Maj. Art Chin, Maj. John Wong Pan-yang, and Capt. Chan Kee-Wong, even in their older and slower biplanes,^[64]^[65] proved more than able to hold their own against the sleek A5Ms in dogfights, and it also proved to be a battle of attrition against the Chinese Air Force.^[66]^[67] At the start of the battle, the local strength of the NRA was around five divisions, or about 70,000 troops, while local Japanese forces comprised about 6,300 marines.^[68] On 23 August, the Chinese Air Force attacked Japanese troop landings at Wusongkou in northern Shanghai with Hawk III fighter-attack planes and P-26/281 fighter escorts, and the Japanese intercepted most of the attack with A2N and A4N fighters from the aircraft carriers Hosho and Ryujo, shooting down several of the Chinese planes while losing a single A4N in the dogfight with Lt. Huang Xinrui in his P-26/281; the Japanese Army reinforcements succeeded in landing in northern Shanghai.^[69]^[70] The Imperial Japanese Army (IJA) ultimately committed over 200,000 troops, along with numerous naval vessels and aircraft, to capture the city. After more than three months of intense fighting, their casualties far exceeded initial expectations.^[71] On 26 October, the Japanese Army captured Dachang, an important strong-point within Shanghai, and on 5 November, additional reinforcements of Japan landed from Hangzhou Bay. Finally, on 9 November, the NRA began a general retreat.

Battle of Nanjing and Nanjing Massacre

Main articles: Battle of Nanjing and Nanjing Massacre
Building on the hard-won victory in Shanghai, the IJA captured the KMT capital city of Nanjing (December 1937) and Northern Shanxi (September–November 1937). These campaigns involved approximately 350,000 Japanese soldiers, and considerably more Chinese.
Historians estimate that between 13 December 1937, and late January 1938, Japanese forces killed or wounded an estimated 40,000 to 300,000 Chinese (mostly civilians) in the "Nanjing Massacre" (also known as the "Rape of Nanjing"), after its fall. However, historian David Askew of Japan's Ritsumeikan University argued that less than 32,000 civilians and soldiers died and no more than 250,000 civilians could have remained in Nanjing, the vast majority of whom had took refuge in the Nanjing Safety Zone, a foreign-established safety zone led by John Rabe who was a Nazi party official.^[72] More than 75% of Nanjing's civilian population had already fled Nanjing before the battle commenced while most of the remainder took refuge in Nanking Safety Zone, leaving only destitute pariah classes like Tanka people and Duo people behind.^{[citation needed]}
In 2005, a history textbook prepared by the Japanese Society for History Textbook Reform which had been approved by the government in 2001, sparked huge outcry and protests in China and Korea. It referred to the Nanjing Massacre and other atrocities such as the Manila massacre as an "incident", glossed over the issue of comfort women, and made only brief references to the death of Chinese soldiers and civilians in Nanjing.^[73] A copy of the 2005 version of a junior high school textbook titled New History Textbook found that there is no mention of the "Nanjing Massacre" or the "Nanjing Incident".

Indeed, the only one sentence that referred to this event was: "they [the Japanese troops] occupied that city in December".^[74] As of 2015^[update], some right-wing Japanese negationists deny that the massacre occurred, and have successfully lobbied for revision and exclusion of information in Japanese schoolbooks.^[75]
At the start of 1938, the leadership in Tokyo still hoped to limit the scope of the conflict to occupy areas around Shanghai, Nanjing and most of northern China. They thought this would preserve strength for an anticipated showdown with the Soviet Union, but by now the Japanese government and GHQ had effectively lost control of the Japanese army in China. With many victories achieved, Japanese field generals escalated the war in Jiangsu in an attempt to wipe out Chinese resistance, but were defeated at the Battle of Taierzhuang (March–April 1938). Afterwards the IJA changed its strategy and deployed almost all of its existing armies in China to attack the city of Wuhan, which had become the political, economic and military center of rump China, in hopes of destroying the fighting strength of the NRA and of forcing the KMT government to negotiate for peace.^[76] On 6 June, they captured Kaifeng, the capital of Henan, and threatened to take Zhengzhou, the junction of the Pinghan and Longhai railways. To prevent Japanese advances in western and southern China, Chiang Kai-shek, at the suggestion of Chen Guofu, ordered the opening of the dikes on the Yellow River near Zhengzhou. The original plan was to destroy the dike in Zhaokou, but due to difficulties in that place, the Huayuankou dike on the south bank was destroyed on 5 June and 7 June by excavation, with flood waters over eastern Henan, central Anhui, and north central Jiangsu. The floods covered and destroyed thousands of square kilometers of agricultural land and displaced the mouth of the Yellow River hundreds of miles to the south. Thousands of villages were flooded or destroyed and several million villagers were forced to evacuate from their homes. 400,000 people including Japanese soldiers drowned and an additional 10 million became refugees. Rivers were filled with corpses as Tanka boat dwellers drowned from boat capsize. Damage to plantations also affected the population which generated later hunger. Despite this, the Japanese captured Wuhan on 27 October 1938, forcing the KMT to retreat to Chongqing (Chungking), but Chiang Kai-shek still refused to negotiate, saying he would only consider talks if Japan agreed to withdraw to the pre-1937 borders. In 1937, the Japanese Imperial Army quickly marched into the heart of Chinese territory.
With Japanese casualties and costs mounting, the Imperial General Headquarters attempted to break Chinese resistance by ordering the air branches of their navy and air branches of their navy and army to launch the war's first massive air raids on civilian targets. Japanese raiders hit the Kuomintang's newly established provisional capital of Chongqing and most other major cities in unoccupied China, leaving many people either dead, injured, or homeless.
From the beginning of 1939, the war entered a new phase with the unprecedented defeat of the Japanese at Battle of Suixian–Zaoyang, 1st Battle of Changsha, Battle of South Guangxi and Battle of Zaoyi. These outcomes encouraged the Chinese to launch their first large-scale counter-offensive against the IJA in early 1940; however, due to its low military-industrial capacity and limited experience in modern warfare, this offensive was defeated. Afterwards Chiang could not risk any more all-out offensive campaigns given the poorly trained, under-equipped, and disorganized state of his armies and opposition to his leadership both within the Kuomintang and in China in general. He had lost a substantial portion of his best trained and equipped troops in the Battle of Shanghai and was at times at the mercy of his generals, who maintained a high degree of autonomy from the central KMT government.
During the offensive, Hui forces in Suiyuan under generals Ma Hongbin and Ma Buqing routed the Imperial Japanese Army and their puppet Inner Mongol forces and prevented the planned Japanese advance into northwest China. Ma Hongbin's father Ma Fulu had fought against Japanese in the Boxer Rebellion. General Ma Biao led Hui, Salar and Dongxiang cavalry to defeat the Japanese at the Battle of Huaiyang.^[77]^[78]^[79]^[80]^[81]^[82]^[83]^[84]^[85] Ma Biao fought against the Japanese in the Boxer Rebellion.

After 1940, the Japanese encountered tremendous difficulties in administering and garrisoning the seized territories, and tried to solve its occupation problems by implementing a strategy of creating friendly puppet governments favorable to Japanese interests in the territories conquered, most prominently the Nanjing Nationalist Government headed by former KMT premier Wang Jingwei. However, atrocities committed by the Imperial Japanese Army, as well as Japanese refusal to delegate any real power, left the puppets very unpopular and largely ineffective. The only success the Japanese had was to recruit a large Collaborationist Chinese Army to maintain public security in the occupied areas.

By 1941, Japan held most of the eastern coastal areas of China and Vietnam, but guerilla fighting continued in these occupied areas. Japan had suffered high casualties from unexpectedly stubborn Chinese resistance, and neither side could make any swift progress in the manner of Nazi Germany in Western Europe.
By 1943, Guangdong had experienced famine. As the situation worsened, New York Chinese compatriots received a letter stating that 600,000 people were killed in Siyi by starvation.^[86]

Chinese resistance strategy

The basis of Chinese strategy before the entrance of the Western Allies can be divided into two periods as follows:

First Period: 7 July 1937 (Battle of Lugou Bridge) – 25 October 1938 (end of the Battle of Wuhan with the fall of the city).

Second Period: 25 October 1938 (following the Fall of Wuhan) – December 1941 (before the Allies' New York Chinese compatriots received a letter stating that 600,000 people were killed in Siyi by starvation.^[86]

Unlike Japan, China was unprepared for total war and had little military-industrial strength, no mechanized divisions, and few armoured forces.^[87] Up until the mid-1930s, China had hoped that the League of Nations would provide countermeasures to Japan's aggression. In addition, the Kuomintang (KMT) government was mired in a civil war against the Communist Party of China (CPC), as Chiang Kai-shek was quoted: "the Japanese are a disease of the skin, the Communists are a disease of the heart". The Second United Front between the KMT and CPC was never truly unified, as each side was preparing for a showdown with the other once the Japanese were driven out.

Even under these extremely unfavorable circumstances, Chiang realized that to win support from the United States and other foreign nations, China had to prove it was capable of fighting. Knowing a hasty retreat would discourage foreign aid, Chiang resolved to make a stand at Shanghai, using the best of his German-trained divisions to defend China's largest and most industrialized city from the Japanese. The battle lasted over three months, saw heavy casualties on both sides, and ended with a Chinese retreat towards Nanjing, but proved that China would not be easily defeated and showed its determination to the world. The battle became an enormous morale booster for the Chinese people, as it decisively refuted the Japanese boast that Japan could conquer Shanghai in three days and China in three months.
Afterwards, China began to adopt the Fabian strategy of "trading space for time" (simplified Chinese: 以空间换取时间; traditional Chinese: 以空間換取時間). The Chinese army would put up fights to delay the Japanese advance to northern and eastern cities, allowing the home front, with its professionals and key industries, to retreat west into Chongqing.

Afterwards, China began to adopt the Fabian strategy of "trading space for time" (simplified Chinese: 以空间换取时间; traditional Chinese: 以空間換取時間). The Chinese army would put up fights to delay the Japanese advance to northern and eastern cities, allowing the home front, with its professionals and key industries, to retreat west into Chongqing. As a result of Chinese troops' scorched earth strategies, dams and levees were intentionally sabotaged to create massive flooding, which caused thousands of deaths and many more to seek refuge.
During this period, the main Chinese objective was to drag out the war for as long as possible in a war of attrition, thereby exhausting Japanese resources while building up Chinese military capacity. American general Joseph Stilwell called this strategy "winning by outlasting". The NRA adopted the concept of "magnetic warfare" to attract advancing Japanese troops to definite points where they were subjected to ambush, flanking attacks, and encirclements in major engagements. The most prominent example of this tactic was the successful defense of Changsha in 1939 (and again in 1941), in which heavy casualties were inflicted on the IJA.
Local Chinese resistance forces, organized separately by both the communists and KMT, continued their resistance in occupied areas to pester the enemy and make their administration over the vast land area of China difficult. In 1940, the Chinese Red Army launched a major offensive in north China, destroying railways and a major coal mine. These constant harassment and sabotage operations deeply frustrated the Imperial Japanese Army and led them to employ the "Three Alls Policy" (kill all, loot all, burn all) (三光政策, Hanyu Pinyin: Sānguāng Zhèngcè, Japanese On: Sankō Seisaku). It was during this period that the bulk of Japanese war crimes were committed.

It was during this period that the bulk of Japanese war crimes were committed.
By 1941, Japan had occupied much of north and coastal China, but the KMT central government and military had retreated to the western interior to continue their resistance, while the Chinese communists remained in control of base areas in Shaanxi. In the occupied areas, Japanese control was mainly limited to railroads and major cities ("points and lines"). They did not have a major military or administrative presence in the vast Chinese countryside, where Chinese guerrillas roamed freely.
The United States strongly supported China starting in 1937 and warned Japan to get out.^[88] American financial and military aid began to flow.^[89] Claire Lee Chennault commanded the 1st American Volunteer Group (nicknamed Flying Tigers), with American pilots flying American warplanes painted with the Chinese flag to attack the Japanese. He headed both the volunteer group and the uniformed U.S. Army Air Forces units that replaced it in 1942.^[90] However, it was the Soviets that provided the greatest material help for China's war of resistance against the imperial Japanese invasion with fighter aircraft for the Nationalist Chinese Air Force and artillery and armour for the Chinese Army through the Sino-Soviet Treaty; Operation Zet also provided for a group of Soviet volunteer combat aviators to join the Chinese Air Force in the fight against the Japanese occupation from late 1937 through 1939. The United States cut off Japan's main oil supplies in 1941 to pressure Japan to compromise regarding China, but Japan instead attacked American, British and Dutch possessions in the western Pacific.^[91]
After the Mukden Incident in 1931, Chinese public opinion was strongly critical of Manchuria's leader, the "young marshal" Zhang Xueliang, for his nonresistance to the Japanese invasion, even though the Kuomintang central government was also responsible for this policy, giving Zhang an order to "improvise" while not offering support. After losing Manchuria to the Japanese, Zhang and his Northeast Army were given the duty of suppressing the Red Army of the Chinese Communist Party (CPC) in Shaanxi after their Long March. This resulted in great casualties for his Northeast Army, which received no support in manpower or weaponry from Chiang Kai-shek.
On 12 December 1936, a deeply disgruntled Zhang Xueliang kidnapped Chiang Kai-shek in Xi'an, hoping to force an end to the conflict between KMT and CPC. To secure the release of Chiang, the KMT agreed to a temporary end to the Chinese Civil War and, on 24 December, the creation of a United Front between the CPC and KMT against Japan. The alliance having salutary effects for the beleaguered CPC, they agreed to form the New Fourth Army and the 8th Route Army and place them under the nominal control of the NRA. In agreement with KMT Shaan-Gan-Ning Border Region and Shanxi-Chahar-Hebei Border Region were created. They were controlled by CCP. The CPC's Red Army fought alongside KMT forces during the kidnapped Chiang Kai-shek in Xi'an, hoping to force an end to the conflict between KMT and CPC. To secure the release of Chiang, the KMT agreed to a temporary end to the Chinese Civil War and, on 24 December, the creation of a United Front between the CPC and KMT against Japan. The alliance having salutary effects for the beleaguered CPC, they agreed to form the New Fourth Army and the 8th Route Army and place them under the nominal control of the NRA. In agreement with KMT Shaan-Gan-Ning Border Region and Shanxi-Chahar-Hebei Border Region were created. They were controlled by CCP. The CPC's Red Army fought alongside KMT forces during the Battle of Taiyuan, and the high point of their cooperation came in 1938 during the Battle of Wuhan.
Despite Japan's steady territorial gains in northern China, the coastal regions, and the rich Yangtze River Valley in central China, the distrust between the two antagonists was scarcely veiled. The uneasy alliance began to break down by late 1938, partially due to the Communists' aggressive efforts to expand their military strength by absorbing Chinese guerrilla forces behind Japanese lines. Chinese militia who refused to switch their allegiance were often labelled "collaborators" and attacked by CPC forces. For example, the Red Army led by He Long attacked and wiped out a brigade of Chinese militia led by Zhang Yin-wu in Hebei in June 1939.^[92] Starting in 1940, open conflict between Nationalists and Communists became more frequent in the occupied areas outside of Japanese control, culminating in the New Fourth Army Incident in January 1941.
Afterwards, the Second United Front completely broke down and Chinese Communists leader Mao Zedong outlined the preliminary plan for the CPC's eventual seizure of power from Chiang Kai-shek. Mao began his final push for consolidation of CPC power under his authority, and his teachings became the central tenets of the CPC doctrine that came to be formalized as "Mao Zedong Thought". The communists also began to focus most of their energy on building up their sphere of influence wherever opportunities were presented, mainly through rural mass organizations, administrative, land and tax reform measures favoring poor peasants; while the Nationali

The communists also began to focus most of their energy on building up their sphere of influence wherever opportunities were presented, mainly through rural mass organizations, administrative, land and tax reform measures favoring poor peasants; while the Nationalists attempted to neutralize the spread of Communist influence by military blockade of areas controlled by CPC and fighting the Japanese at the same time.^[93]
Following the attack on Pearl Harbor, the United States declared war against Japan, and within days China joined the Allies in formal declaration of war against Japan, Germany and Italy.^[94] As the Western Allies entered the war against Japan, the Sino-Japanese War would become part of a greater conflict, the Pacific theatre of World War II. Almost immediately, Chinese troops achieved another decisive victory in the Battle of Changsha, which earned the Chinese government much prestige from the Western Allies. President Franklin D. Roosevelt referred to the United States, United Kingdom, Soviet Union and China as the world's "Four Policemen", elevating the international status of China to an unprecedented height after the century of humiliation at the hands of various imperialist powers.
Knowledge of Japanese naval movements in the Pacific was provided to the American Navy by the Sino-American Cooperative Organization (SACO) which was run by the Chinese intelligence head Dai Li.^[95] Philippine and Japanese ocean weather was affected by weather originating near northern China.^[96] The base of SACO was located in Yangjiashan.^[97]
Chiang Kai-shek continued to receive supplies from the United States. However, in contrast to the Arctic supply route to the Soviet Union which stayed open through most of the war, sea routes to China and the Yunnan–Vietnam Railway had been closed since 1940. Therefore, between the closing of the Burma Road in 1942 and its re-opening as the Ledo Road in 1945, foreign aid was largely limited to what could be flown in over "The Hump". In Burma, on 16 April 1942, 7,000 British soldiers were encircled by the Japanese 33rd Division during the Battle of Yenangyaung and rescued by the Chinese 38th Division.^[98] After the Doolittle Raid, the Imperial Japanese Army conducted a massive sweep through Zhejiang and Jiangxi of China, now known as the Zhejiang-Jiangxi Campaign, with the goal of finding the surviving American airmen, applying retribution on the Chinese who aided them and destroying air bases. The operation started 15 May 1942, with 40 infantry battalions and 15–16 artillery battalions but was repelled by Chinese forces in September.^[99] During this campaign, the Imperial Japanese Army left behind a trail of devastation and also spread cholera, typhoid, plague and dysentery pathogens. Chinese estimates allege that as many as 250,000 civilians, the vast majority of whom were destitute Tanka boat people and other pariah ethnicities unable to flee, may have died of disease.^[100]^[101]^[102] It caused more than 16 million civilians to evacuate far away deep inward China. 90% of Ningbo's population had already fled before battle started.^[103]
Most of China's industry had already been captured or destroyed by Japan, and the Soviet Union refused to allow the United States to supply China through Kazakhstan into Xinjiang as the Xinjiang warlord Sheng Shicai had turned anti-Soviet in 1942 with Chiang's approval. For these reasons, the Chinese government never had the supplies and equipment needed to mount major counter-offensives. Despite the severe shortage of matériel, in 1943, the Chinese were successful in repelling major Japanese offensives in Hubei and Changde.
Chiang was named Allied commander-in-chief in the China theater in 1942. American general Joseph Stilwell served for a time as Chiang's chief of staff, while simultaneously commanding American forces in the China-Burma-India Theater. For many reasons, relations between Stilwell and Chiang soon broke down. Many historians (such as Barbara W. Tuchman) have suggested it was largely due to the corruption and inefficiency of the Kuomintang (KMT) government, while others (such as Ray Huang and Hans van de Ven) have depicted it as a more complicated situation. Stilwell had a strong desire to assume total control of Chinese troops and pursue an aggressive strategy, while Chiang preferred a patient and less expensive strategy of out-waiting the Japanese. Chiang continued to maintain a defensive posture despite Allied pleas to actively break the Japanese blockade, because China had already suffered tens of millions of war casualties and believed that Japan would eventually capit

Stilwell had a strong desire to assume total control of Chinese troops and pursue an aggressive strategy, while Chiang preferred a patient and less expensive strategy of out-waiting the Japanese. Chiang continued to maintain a defensive posture despite Allied pleas to actively break the Japanese blockade, because China had already suffered tens of millions of war casualties and believed that Japan would eventually capitulate in the face of America's overwhelming industrial output. For these reasons the other Allies gradually began to lose confidence in the Chinese ability to conduct offensive operations from the Asian mainland, and instead concentrated their efforts against the Japanese in the Pacific Ocean Areas and South West Pacific Area, employing an island hopping strategy.^[104]
Long-standing differences in national interest and political stance among China, the United States, and the United Kingdom remained in place. British Prime Minister Winston Churchill was reluctant to devote British troops, many of whom had been routed by the Japanese in earlier campaigns, to the reopening of the Burma Road; Stilwell, on the other hand, believed that reopening the road was vital, as all China's mainland ports were under Japanese control. The Allies' "Europe First" policy did not sit well with Chiang, while the later British insistence that China send more and more troops to Indochina for use in the Burma Campaign was seen by Chiang as an attempt to use Chinese manpower to defend British colonial possessions. Chiang also believed that China should divert its crack army divisions from Burma to eastern China to defend the airbases of the American bombers that he hoped would defeat Japan through bombing, a strategy that American general Claire Lee Chennault supported but which Stilwell strongly opposed. In addition, Chiang voiced his support of Indian independence in a 1942 meeting with Mahatma Gandhi, which further soured the relationship between China and the United Kingdom.^[105]
American and Canadian-born Chinese were recruited to act as covert operatives in Japanese-occupied China (Canadian-born Chinese who had not been granted citizenship were trained by the British army). Employing their racial background as a disguise, their mandate was to blend in with local citizens and wage a campaign of sabotage. Activities focused on destruction of Japanese transportation of supplies (signaling bomber destruction of railroads, bridges).^[106] Chinese forces invaded northern Burma in late 1943 besieged Japanese troops in Myitkyina and captured Mount Song.^[107] The British and Commonwealth forces had their operation in Mis

The United States saw the Chinese theater as a means to tie up a large number of Japanese troops, as well as being a location for American airbases from which to strike the Japanese home islands. In 1944, with the Japanese position in the Pacific deteriorating rapidly, the IJA mobilized over 500,000 men and launched Operation Ichi-Go, their largest offensive of World War II, to attack the American airbases in China and link up the railway between Manchuria and Vietnam. This brought major cities in Hunan, Henan and Guangxi under Japanese occupation. The failure of Chinese forces to defend these areas encouraged Stilwell to attempt to gain overall command of the Chinese army, and his subsequent showdown with Chiang led to his replacement by Major General Albert Coady Wedemeyer. In 1944, China came off of several victories against Japan in Burma leading to overconfidence. Nationalist China also diverted soldiers to Xinjiang since 1942 to retake the province from the Soviet client Sheng Shicai whose puppet army was backed by the Soviet Red Army 8th Regiment in Hami, Xinjiang since the Soviet invasion of Xinjiang in 1934 when the Soviets occupied northern Xinjiang and the Islamic rebellion in Xinjiang in 1937 when the Soviets occupied southern Xinjiang as well placing all of Xinjiang under Sheng Shicai and Soviet Communist control. The fighting then escalated in early 1944 with the Ili Rebellion with Soviet backed Uyghur Communist rebels, causing China to fight enemies on two fronts with 120,000 Chinese soldiers fighting against the Ili rebellion. The aim of the Japanese Operation Ichigo was to destroy American airfields in southern China that threatened the Japanese home islands with bombing and to link railways in Beijing, Hankou and Canton cities from northern China in Beijing to southern China's coast on Canton. Japan was alarmed by American air raids against Japanese forces in Taiwan's Hsinchu airfield by American bombers based in southern China, correctly deducing that southern China could become the base of a major American bombing campaign against the Japanese home islands so Japan resolved to destroy and capture all airbases where American bombers operated from in Operation Ichigo. Chiang Kai-shek and the Republic of China authorities deliberately ignored and dismissed a tip passed on to the Chinese government in Chongqing by the French military that the French picked up in colonial French Indochina on the impending Japanese offensive to link the three cities. The Chinese military believed it to be a fake tip planted by Japan to mislead them since only 30,000 Japanese soldiers started the first maneuver of Operation Ichigo in northern China crossing the Yellow river so the Chinese assumed it would be a local operation in northern China only. Another major factor was that the battlefront between China and Japan was static and stabilized since 1940 and continued for four years that way until Operation Ichigo in 1944 so Chiang assumed that Japan would continue the same posture and remain behind the lines in pre-1940 occupied territories of North China only bolstering the puppet Chinese government of Wang Jingwei and exploiting resources there. The Japanese had indeed acted this way from 1940 to 1944, with the Japanese only making a few failed weak attempts to capture China's provisional capital in Chongqing on the Yangtze river which they quickly abandoned and gave up on before 1944. Japan also exhibited no intention before of linking the transcontinental Beijing Hankow Canton railways. China also was made confident by its three victories in a row defending Changsha against Japan at the Battle of Changsha (1939), Battle of Changsha (1941), and Battle of Changsha (1942). China had also defeated Japan in the India-Burma theater in Southeast Asia with X Force and Y Force and the Chinese could not believe Japan had carelessly let information slip into French hands, believing Japan deliberately fed misinformation to the French to divert Chinese troops from India and Burma towards China. China believed the Burma theater to be far more important for Japan than southern China and that Japanese forces in southern China would continue to assume a defensive posture only. China believed the initial Japanese attack in Ichigo to be a localized feint and distraction in northern China so Chinese troops numbering 400,000 in North China deliberately withdrew without a fight when Japan attacked, assuming it was just another localized operation after which the Japanese would withdraw. This mistake led to the collapse of Chinese defensive lines as the Japanese soldiers which eventually numbered in the hundreds of thousands kept pressing the attack from northern China to central China to southern China's provinces as Chinese soldiers deliberately withdrew leading to confusion and collapse, except at the Defense of Hengyang where 17,000 outnumbered Chinese soldiers held out against over 110,000 Japanese soldiers for months in the longest siege of the war inflicting 19,000–60,000 deaths on the Japanese. At Tushan in Guizhou province, the Nationalist government of China was forced to deploy five armies of the 8th war zone that they were using for the entire war up to Ichigo to contain the Communist Chinese to instead fight Japan. But at that point, dietary deficiencies of Japanese soldiers and increasing casualties suffered by Japan forced Japan to end Operation Ichigo in Guizhou causing the operation to cease. After Operation Ichigo, Chiang Kai-shek started a plan to withdraw Chinese troops from the Burma theatre against Japan in Southeast Asia for a counter offensive called "White Tower" and "Iceman" against Japanese soldiers in China in 1945.^[110]
By the end of 1944 Chinese troops under the command of Sun Li-jen attacking from India, and those under Wei Lihuang attacking from Yunnan, joined forces in Mong-Yu, successfully driving the Japanese out of North Burma and securing the Ledo Road, China's vital supply artery.^[111] In Spring 1945 the Chinese launched offensives that retook Hunan and Guangxi. With the Chinese army progressing well in training and equipment, Wedemeyer planned to launch Operation Carbonado in summer 1945 to retake Guangdong, thus obtaining a coastal port, and from there drive northwards toward Shanghai. However, the atomic bombings of Hiroshima and Nagasaki and Soviet invasion of Manchuria hastened Japanese surrender and these plans were not put into action.^[112]
Germany and the Soviet Union provided aid to China at the start of the Second Sino-Japanese War. By 1940 the United States had become China's main diplomatic, financial and military supporter.^[113]

Overseas Chinese

Over 3,200 overseas Chinese drivers and motor vehicle mechanics embarked to wartime China to support military and logistics supply lines, especially through Indo-China, which became of absolute tantamount importance when the Japanese cut-off all ocean-access to China's interior with the capture of Nanning after the Battle of South Guangxi.^[114] Overseas Chinese communities in the U.S. raised money and nurtured talent in response to Imperial Japan's aggressions in China, which helped to fund an entire squadron of Boeing P-26 Model 281 fighter planes purchased for the looming war situation between China and the Empire of Japan; over a dozen Chinese-American aviators, including John "Buffalo" Huang, Arthur Chin, Hazel Ying Lee, Chan Kee-Wong et al., formed the original contingent of foreign volunteer aviators to join the Chinese Air Force (some provincial or warlord air forces, but ultimately all integrating into the centralized Chinese Air Force) in the "patriotic call to duty for the motherland" to fight against the Imperial Japanese invasion.^[115]^[116]^[117]^[118] Several of the original Chinese-American volunteer pilots were sent to Lagerlechfeld Air Base in Germany for aerial-gunnery training by the Chinese Air Force in 1936.^[119]

After Germany and Japan sign
After Germany and Japan signed the anti-communist Anti-Comintern Pact, the Soviet Union hoped to keep China fighting, in order to deter a Japanese invasion of Siberia and save itself from a two-front war. In September 1937, they signed the Sino-Soviet Non-Aggression Pact and approved Operation Zet, the formation of a secret Soviet volunteer air force, in which Soviet technicians upgraded and ran some of China's transportation systems. Bombers, fighters, supplies and advisors arrived, including Soviet general Vasily Chuikov, future victor in the Battle of Stalingrad. Prior to the Western Allies, the Soviets provided the most foreign aid to China: some $250 million in credits for munitions and other supplies. The Soviet Union defeated Japan in the Battles of Khalkhin Gol in May – September 1939, leaving the Japanese reluctant to fight the Soviets again.^[123] In April 1941, Soviet aid to China ended with the Soviet–Japanese Neutrality Pact and the beginning of the Great Patriotic War. This pact enabled the Soviet Union to avoid fighting against Germany and Japan at the same time. In August 1945, the Soviet Union annulled the neutrality pact with Japan and invaded Manchuria, Inner Mongolia, the Kuril Islands, and northern Korea. The Soviets also continued to support the Chinese Communist Party. In total, 3,665 Soviet advisors and pilots served in China,^[124] and 227 of them died fighting there.^[125]

The United States generally avoided taking sides between Japan and China until 1940, providing virtually no aid to China in this period. For instance, the 1934 Silver Purchase Act signed by President Roosevelt caused chaos in China's economy which helped the Japanese war effort. The 1933 Wheat and Cotton Loan mainly benefited American producers, while aiding to a smaller extent both Chinese and Japanese alike. This policy was due to US fear of breaking off profitable trade ties with Japan, in addition to US officials and businesses perception of China as a potential source of massive profit for the US by absorbing surplus American products, as William Appleman Williams states.^[126]
From December 1937, events such as the Japanese attack on USS Panay and the Nanjing Massacre swung public opinion in the West sharply against Japan and increased their fear of Japanese expansion, which prompted the United States, the United Kingdom, and France to provide loan assistance for war supply contracts to China. Australia also prevented a Japanese government-owned company from taking over an iron mine in Australia, and banned iron ore exports in 1938.^[127] However, in July 1939, negotiations between Japanese Foreign Minister Arita Khatira and the British Ambassador in Tokyo, Robert Craigie, led to an agreement by which Great Britain recognized Japanese conquests in China.

At the same time, the US government extended a trade agreement with Japan for six months, then fully restored it. Under the agreement, Japan purchased trucks for the Kwantung Army,^[128] machine tools for aircraft factories, strategic materials (steel and scrap iron up to 16 October 1940, petrol and petroleum products up to 26 June 1941),^[129] and various other much-needed supplies.
In a hearing before the United States Congress House of Representatives Committee on Foreign Affairs on Wednesday, 19 April 1939, the acting chairman Sol Bloom and other Congressmen interviewed Maxwell S. Stewart, a former Foreign Policy Association research staff and economist who charged that America's Neutrality Act and its "neutrality policy" was a massive farce which only benefited Japan and that Japan did not have the capability nor could ever have invaded China without the massive amount of raw material America exported to Japan. America exported far more raw material to Japan than to China in the years 1937–1940.^[130]^[131]^[132]^[133] According to the United States Congress, the U.S.'s third largest export destination was Japan until 1940 when France overtook it due to France being at war too. Japan's military machine acquired all the war materials, automotive equipment, steel, scrap iron, copper, oil, that it wanted from the United States in 1937–1940 and was allowed to purchase aerial bombs, aircraft equipment, and aircraft from America up to the summer of 1938. War essentials exports from the United States to Japan increased by 124% along with a general increase of 41% of all exports from 1936 to 1937 when Japan invaded China. Japan's war economy was fueled by exports to the United States at over twice the rate immediately preceding the war.^[134] 41.6 percent of pig iron, 59.7 percent of scrap iron and 91.2 percent of automobiles and automobile parts of Japan were imported from the United States, as Japan needed to supply huge armies some aggregating 800,000 soldiers, in China.^[135] According to the 1939 Reports to the Annual National Convention of the American Legion, in 1936 1,467,639 tons of scrap metal from all foreign nations were exported to Japan while since 1937 Japan's dependence on the United States of America grew massively for war materials and supplies against China.^[136]^[137] The US contributed massively to the Japanese war economy in 1937 with 20.4% of zinc, 48.5% of engines and machinery, 59.7% of iron, 41.6% of pig iron, 60.5% of oil, 91.2% of automobiles and parts, 92.9% of copper of Japan were imported from the U.S. in 1937 according to a hearing by the United States Congress Senate Committee on Foreign Relations.^[138]^[139]^[140]^[141] From 1937 to 1940, the US exported a total of $986.7 million to Japan. The total value of military supplies was $703.9 million. During the Japanese war against China, 54.4% of Japan's weapons and supplies were provided by Americans. 76% of Japanese planes came from the US in 1938, and all lubricating oil, machine tools, special steel, high-test aircraft petrol came from the US, as did 59.7% of Japan's scrap iron and 60.5% of Japan's petrol in 1937. Japan freely bought weapons from U.S. companies, even as the U.S. Government barred the sale of weapons to Republican Spain. From 1937 to 1940, Japanese bombers were fueled with American oil and Japanese weapons were made out of American scrap iron. America supplied Japan with 54.4% of its war materials in 1937 when Japan invaded China, increasing to 56% in 1938. Japan by itself had scant and meager resources and could not have prosecuted war against China or dreamed of empire without massive imports.^[142] The Dutch East Indies, the British Empire and United States of America were the top exporters of war supplies for Japan's military against China in 1937, with 7.4% from the Dutch, 17.5% from the British and 54.4% from the United States of America. Oil, scrap iron and rubber were all sold by France, the Netherlands, Britain and the U.S. to Japan after the invasion of China in 1937.^[143]^[144] In 15 Sep 1939 American oil companies unveiled contracts to deliver three million barrels of petroleum to the Japanese Navy.
Japan invaded and occupied the northern part of French Indochina (present-day Vietnam, Laos, Cambodia) in September 1940 to prevent China from receiving the 10,000 tons of materials delivered monthly by the Allies via the Haiphong–Yunnan Fou Railway line.
On 22 June 1941, Germany attacked the Soviet Union. In spite of non-aggression pacts or trade connections, Hitler's assault threw the world into a frenzy of re-aligning political outlooks and strategic prospects.
On 21 July, Japan occupied the southern part of French Indochina (southern Vietnam and Cambodia), contravening a 1940 "gentlemen's agreement" not to move into southern French Indochina. From bases in Cambodia and southern Vietnam, Japanese planes could attack Malaya, Singapore, and the Dutch East Indies. As the Japanese occupation of northern French Indochina in 1940 had already cut off supplies from the West to China, the move into southern French Indochina was viewed as a direct threat to British and Dutch colonies. Many principal figures in the Japanese government and military (particularly the navy) were against the move, as they foresaw that it would invite retaliation from the West.

On 24 July 1941, Roosevelt requested Japan withdraw all its forces from Indochina. Two days later the US and the UK began an oil embargo; two days after that the Netherlands joined them. This was a decisive moment in the Second Sino-Japanese War. The loss of oil imports made it impossible for Japan to continue operations in China on a long-term basis. It set the stage for Japan to launch a series of military attacks against the Allies, including the attack on Pearl Harbor on 7 December 1941.

American Volunteer Group (AVG), or Flying Tigers, to replace the withdrawn Soviet volunteers and aircraft. Contrary to popular perception, the Flying Tigers did not enter actual combat until after the United States had declared war on Japan. Led by Claire Lee Chennault, their early combat success of 300 kills against a loss of 12 of their newly introduced shark painted P-40 fighters heavily armed with 6X50 caliber machine guns and very fast diving speeds earned them wide recognition at a time when the Chinese Air Force and Allies in the Pacific and SE Asia were suffering heavy losses, and soon afterwards their "boom and zoom" high-speed hit-and-run dissimilar air combat tactics would be adopted by the United States Army Air Forces.^[145]

The India–China airlift delivered approximately 650,000 tons of materiel to China at a cost of 1,659 men and 594 aircraft.

The Sino-American Cooperative Organization^[146]^[147]^[148] was an organization created by the SACO Treaty signed by the Republic of China and the United States of America in 1942 that established a mutual intelligence gathering entity in China between the respective nations against Japan. It operated in China jointly along with the Office of Strategic Services (OSS), America's first intelligence agency and forerunner of the CIA while also serving as joint training program between the two nations. Among all the wartime missions that Americans set up in China, SACO was the only one that adopted a policy of "total immersion" with the Chinese. The "Rice Paddy Navy" or "What-the-Hell Gang" operated in the China-Burma-India theater, advising and training, forecasting weather and scouting landing areas for USN fleet and Gen Claire Chennault's 14th AF, rescuing downed American flyers, and intercepting Japanese radio traffic. An underlying mission objective during the last year of war was the development and preparation of the China coast for Allied penetration and occupation. The Foochow (Fujian Province) was scouted as a potential staging area and springboard for the future military landing of the Allies of World War II in Japan.
In February 1941 a Sino-British agreement was forged whereby British troops would assist the Chinese "Surprise Troops" units of guerrillas already operating in China, and China would assist Britain in Burma.^[149]
A British-Australian commando operation, Mission 204, was initialized in February 1942 to provide training to Chinese guerilla troops. The mission conducted two operations, mostly in the provinces of Yunnan and Jiangxi. The first phase achieved very little but a second more successful phase was conducted before withdrawal.^[150]
Commandos working with the Free Thai Movement also operated in China, mostly while on their way into Thailand.^[151]

After the Japanese blocked the Burma Road in April 1942, and before the Ledo Road was finished in early 1945, the majority of US and British supplies to the Chinese had to be delivered via airlift over the eastern end of the Himalayan Mountains known as the Hump. Flying over the Himalayas was extremely dangerous, but the airlift continued daily to August 1945, at great cost in men and aircraft.
The Chinese Kuomintang also supported the Vietnamese Việt Nam Quốc Dân Đảng (VNQDD) in its battle against French and Japanese imperialism.
In Guangxi, Chinese military leaders were organizing Vietnamese nationalists against the Japanese. The VNQDD had been active in Guangxi and some of their members had joined the KMT army.^[152] Under the umbrella of KMT activities, a broad alliance of nationalists emerged. With Ho at the forefront, the Viet Nam Doc Lap Dong Minh Hoi (Vietnamese Independence League, usually known as the Viet Minh) was formed and based in the town of Jingxi.^[152] The pro-VNQDD nationalist Ho Ngoc Lam, a KMT army officer and former disciple of Phan Bội Châu,^[153] was named as the deputy of Phạm Văn Đồng, later to be Ho's Prime Minister. The front was later broadened and renamed the Viet Nam Giai Phong Dong Minh (Vietnam Liberation League).^[152]

The Viet Nam Revolutionary League was a union of various Vietnamese nationalist groups, run by the pro Chinese VNQDD. Chinese KMT General Zhang Fakui created the league to further Chinese influence in Indochina, against the French and Japanese. Its stated goal was for unity with China under the Three Principles of the People, created by KMT founder Dr. Sun and opposition to Japanese and French Imperialists.^[154]^[155] The Revolutionary League was controlled by Nguyen Hai Than, who was born in China and could not speak Vietnamese. General Zhang shrewdly blocked the Communists of Vietnam, and Ho Chi Minh from entering the league, as Zhang's main goal was Chinese influence in Indochina.^[156] The KMT utilized these Vietnamese nationalists during World War II against Japanese forces.^[152] Franklin D. Roosevelt, through General Stilwell, privately made it clear that they preferred that the French not reacquire French Indochina (modern day Vietnam, Cambodia, and Laos) after the war was over. Roosevelt offered Chiang Kai-shek control of all of Indochina. It was said that Chiang Kai-shek replied: "Under no circumstances!"^[157]
After the war, 200,000 Chinese troops under General Lu Han were sent by Chiang Kai-shek to northern Indochina (north of the 16th parallel) to accept the surrender of Japanese occupying forces there, and remained in Indochina until 1946, when the French returned.^[158] The Chinese used the VNQDD, the Vietnamese branch of the Chinese Kuomintang, to increase their influence in French Indochina and to put pressure on their opponents.^[159] Chiang Kai-shek threatened the French with war in response to maneuvering by the French and Ho Chi Minh's forces against each other, forcing them to come to a peace agreement. In February 1946, he also forced the French to surrender all of their concessions in China and to renounce their extraterritorial privileges in exchange for the Chinese withdrawing from northern Indochina and allowing French troops to reoccupy the region. Following France's agreement to these demands, the withdrawal of Chinese troops began in March 1946.^[160]^[161]^[162]^[163]
Rebellion occurred in the Xinjiang province in 1937 when a pro-Soviet General Sheng Shicai invaded the province accompanied by Soviet troops. The invasion was resisted by General Ma Hushan of the KMT 36th Division.
General Ma Hushan was expecting help from Nanjing, as he exchanged messages with Chiang regarding the Soviet attack. But, both the Second Sino-Japanese War and the Xinjiang War erupted simultaneously leaving Chiang and Ma Hushan each on their own to confront the Japanese and Soviet forces.

General Ma Hushan was expecting help from Nanjing, as he exchanged messages with Chiang regarding the Soviet attack. But, both the Second Sino-Japanese War and the Xinjiang War erupted simultaneously leaving Chiang and Ma Hushan each on their own to confront the Japanese and Soviet forces.
The Republic of China government was fully aware of the Soviet invasion of Xinjiang province, and Soviet troops moving around Xinjiang and Gansu, but it was forced to mask these maneuvers to the public as "Japanese propaganda" to avoid an international incident and for continued military supplies from the Soviets.^[164]
Because the pro-Soviet governor Sheng Shicai controlled Xinjiang, which was garrisoned with Soviet troops in Turfan, the Chinese government had to keep troops stationed there as well.
General Ma Buqing was in virtual control of the Gansu corridor at that time.^[165] Ma Buqing had earlier fought against the Japanese, but because the Soviet threat was great, Chiang changed Ma's position, in July 1942, by instructing Ma to move 30,000 of his troops to the Tsaidam marsh in the Qaidam Basin of Qinghai.^[166]^[167] Chiang named Ma as Reclamation Commissioner, to threaten Sheng Shicai's southern flank in Xinjiang, which bordered Tsaidam.
After Ma evacuated his positions in Gansu, Kuomintang troops from central China flooded the area, and infiltrated Soviet occupied Xinjiang, gradually reclaiming it and forcing Sheng Shicai to break with the Soviets. The Kuomintang ordered Ma Bufang several times to march his troops into Xinjiang to intimidate the pro-Soviet Governor Sheng Shicai. This helped provide protection for Chinese settling in Xinjiang.^[168]
The Ili Rebellion broke out in Xinjiang when the Kuomintang Hui Officer Liu Bin-Di was killed while fighting Turkic Uyghur rebels in November 1944. The Soviet Union supported the Turkic rebels against the Kuomintang, and Kuomintang forces fought back.^[169]
Japan attempted to reach out to Chinese ethnic minorities in order to rally them to their side against the Han Chinese, but only succeeded with certain Manchu, Mongol, Uyghur and Tibetan elements.
The Japanese attempt to get the Muslim Hui people on their side failed, as many Chinese generals such as Bai Chongxi, Ma Hongbin, Ma Hongkui, and Ma Bufang were Hui. The Japanese attempted to approach Ma Bufang but were unsuccessful in making any agreement with him.^[170&

The Japanese attempted to approach Ma Bufang but were unsuccessful in making any agreement with him.^[170] Ma Bufang ended up supporting the anti-Japanese Imam Hu Songshan, who prayed for the destruction of the Japanese.^[171] Ma became chairman (governor) of Qinghai in 1938 and commanded a group army. He was appointed because of his anti-Japanese inclinations,^[172] and was such an obstruction to Japanese agents trying to contact the Tibetans that he was called an "adversary" by a Japanese agent.^[173]
Hui cemeteries were destroyed for military reasons.^[174] Many Hui fought in the war against the Japanese such as Bai Chongxi, Ma Hongbin, Ma Hongkui, Ma Bufang, Ma Zhanshan, Ma Biao, Ma Zhongying, Ma Buqing and Ma Hushan. Qinghai Tibetans served in the Qinghai army against the Japanese.^[175]^[176]^[177] The Qinghai Tibetans view the Tibetans of Central Tibet (Tibet proper, ruled by the Dalai Lamas from Lhasa) as distinct and different from themselves, and even take pride in the fact that they were not ruled by Lhasa ever since the collapse of the Tibetan Empire.^[178]
Xining was subjected to aerial bombardment by Japanese warplanes in 1941, causing all ethnicities in Qinghai to unite against the Japanese.^[179]^[180] General Han Youwen directed the defense of the city of Xining during air raids by Japanese planes. Han survived an aerial bombardment by Japanese planes in Xining while he was being directed via telephone by Ma Bufang, who hid in an air raid shelter in a military barrack. The bombing resulted in Han being buried in rubble, though he was later rescued.
