China–Iran Relations

Chinese–Iranian relations (, ) refer to the economic, political, and social relations between the People's Republic of China and the Islamic Republic of Iran. In modern times, official diplomatic relations were first established in 1937 between the Republic of China and Pahlavi Iran. The two civilizations had a history of cultural, political and economic exchanges along the Silk Road since at least 200 BCE and possibly earlier.

In March 2021, Iran and China signed a 25-year cooperation agreement that will strengthen the relations between the two countries and include "political, strategic, and economic" components.

History

China–Iran relations refer to the historic diplomatic, cultural, and economic relations between the cultures of China proper and Greater Iran, dating back to ancient times, since at least 200 B.C. The Parthians and Sassanid empires (occupying much of present Iran and Central Asia) had various contacts with the Han, Tang, Song, Yuan, and Ming dynasties.

Han-Parthian era

The Han dynasty diplomat and explorer Zhang Qian, who visited neighboring Bactria and Sogdiana in 126 BCE, made the first known Chinese report on Parthia. In his accounts, Parthia is named "Ānxí" (), a transliteration of " Arsacid", the name of the Parthian dynasty. Zhang Qian clearly identifies Parthia as an advanced urban civilization, whose development he equates to those of Dayuan (in Ferghana) and Daxia (in Bactria).

: "Anxi is situated several thousand '' li'' west of the region of the Great Yuezhi (in Transoxonia). The people are settled on the land, cultivating the fields and growing rice and wheat. They also make wine out of grapes. They have walled cities like the people of Dayuan ( Ferghana), the region contains several hundred cities of various sizes. The coins of the country are made of silver and bear the face of the King. When the King dies, the currency is immediately changed and new coins issued with the face of his successor. The people keep records by writing on horizontal strips of leather. To the west lies Tiaozi (Mesopotamia) and to the north Yancai and Lixuan (Hyrcania)." (Shiji, 123, Zhang Qian quote, trans. Burton Watson).

Following Zhang Qian's embassy and report, the Han conquered Dayuan in the Han-Dayuan war and established the Protectorate of the Western Regions, thereby opening the Silk Road and clashing with Persia sphere of influence (as some satraps were part of the conflict). Commercial relations between China, Central Asia, and Parthia flourished, as many Chinese missions were sent throughout the 1st century BCE:

"The largest of these embassies to foreign states numbered several hundred persons, while even the smaller parties included over 100 members… In the course of one year, anywhere from five to six to over ten parties would be sent out." (Shiji, trans. Burton Watson).

The Parthians were, apparently, very intent on maintaining good relations with China and also sent their own embassies, starting around 110 BC: "When the Han envoy first visited the Kingdom of Anxi (Parthia), the King of Anxi dispatched a party of 20,000 horsemen to meet them on the eastern border of the Kingdom. When the Han envoys set out again to return to China, the King of Anxi dispatched envoys of his own to accompany them. The Emperor was delighted at this." (Shiji, 123, trans. Burton Watson).

Parthians also played a role in the Silk Road transmission of Buddhism from Central Asia to China. An Shih Kao, a Parthian nobleman and Buddhist missionary, went to the Chinese capital Luoyang in 148 CE, where he established temples and became the first man to translate Buddhist scriptures into Chinese. The Persianized kingdom of Kushan became the crossroads for Sino-Indian Buddhist transmissions, with many Iranians translating Sanskrit sutras into Chinese.

Sassanian era

Like their predecessors the Parthians, the Sassanian Empire maintained active foreign relations with China. Ambassadors from Iran frequently traveled to China, with Chinese documents recording the reception of thirteen Sassanian embassies. Commercially, land and sea trade with China was important to both the Sassanian and Chinese Empires. Large numbers of Sassanian coins have been found in southern China, confirming the existence of bilateral maritime trade.

On various occasions, Sassanian kings sent their most talented Persian musicians and dancers to the Chinese imperial court. Both empires benefited from trade along the Silk Road, and shared a common interest in preserving and protecting that trade. They cooperated in guarding the trade routes through central Asia, and both built outposts in border areas to keep caravans safe from nomadic tribes and bandits.

In 547, during the Liang dynasty in China, a Persian embassy paid tribute to the Liang. Amber was recorded as originating from Iran by the Liang Shu (Book of Liang).

There are records of several joint Sassanian and Chinese efforts against their common Hephtalite enemy. Following encroachments by the nomadic Turkic tribes on states in Central Asia, an apparent collaboration between Chinese and Sassanian forces repelled the Turkic advances. Documents from Mount Mogh also note the presence of a Chinese general in the service of the king of Sogdiana at the time of the Arab incursion.

The last members of the Sassanian Empire's royal family fled to Tang China. Following the conquest of Iran by Muslim Arabs, Peroz III, the son of Yazdegerd III, escaped, along with a few Persian nobles, and took refuge in the Chinese imperial court.A History of Chinese civilization, Jacques Gernet. Both Peroz and his son Narsieh (Chinese ''neh-shie'') were given high titles at the Tang court. At least on two occasions, the last possibly in 670, Chinese troops were sent with Peroz to help him against the Arabs to restore him to the Sassanian throne, with mixed results. One possibly ended up in a short rule of Peroz in Sakastan (modern Sistan), from which a little numismatic evidence remains. Narsieh later attained the position of commander of the Chinese imperial guards and his descendants lived in China as respected princes.

Tang and Islamic golden age

After the Islamic conquest, Iran continued to flourish during the Islamic Golden Age, and its relations with China continued. In 751, the Abbasid Caliphate, which ruled Iran, was in dispute with the Tang dynasty of China over the control of the Syr Darya region during the Battle of Talas. The commander of the Abbasid army was Zayid ibn Salih, a Persian, and the commanders of the Tang army were Gao Xianzhi, a Goguryo Korean, alongside Li Siye and Duan Xiushi, both Chinese. After the Abbasids won the battle, relations improved, and there were no more conflicts between China and the Persians.

Zoroastrianism, Manichaeism, and polo were exported to the Tang.

Mongol Yuan

A large number of Central Asian and Persian soldiers, experts, and artisans were recruited by the Mongol empire Yuan dynasty of China. Some of them, known as ''semu'' ("assorted officials"), occupied important official posts in the Yuan state administration. One of the most famous settlers from Bukhara was Sayyid Ajjal Shams al-Din Omar, who is identified as an ancestor of many Chinese Hui lineages and that of Yunnan's Panthay Hui population. His most famous descendant was Zheng He, who became the Ming dynasty's most famous explorer.

Han Chinese general Guo Baoyu campaigned with Genghis in Central Asia against the Khwarezmian Empire, and his grandson Guo Kan campaigned under Hulagu at the Nizari fortresess of Maymundiz and Alamut, as well as at Baghdad in 1258 in Iraq. They were direct descendants of Guo Ziyi.

In the 1220s, the Mongols sent Khitan and Han Chinese administrators to Bukhara and Samarqand to govern, and this was witnessed by Qiu Chuji on his way to meet Genghis Khan in Afghanistan. Chinese siege engineers were deployed in Iran and Iraq by the Ilkhanate. The Khitan Yelü Chucai was sent by the Mongols to Central Asia

The war between Qaidu and Kublai wrecked the economy of Qocho and stopped trade between China and West Asia and Europe. During the war between Kublai Khan and Kaidu, the Uyghurs of Qocho (Gaochang) fled Qaidu's assaults into Gansu, under Yuan control from Turfan, in 1283, placing Yongchang as their capital and between 1270 and 1275, making Gansu's city of Qamil their capital. Uyghur subjects fled along with the royal court. The Mongols sent new people to repopulate the Jaxartes river (lower Syr Darya) and the city of Yangikent (Iamkint or Sakint) after deporting and killing the natives. The upper Yenisei region of Qianqianzhou received many Han Chinese artisans and the western Mongolia-based military base and granary city of Chinqai received many Han Chinese artisans put there by Mongols, as heard in 1221–1222 by Li Zhichang, who was going to Central Asia. Kublai khan sent southern Han Chinese farmers from the Southern Song repeatedly to the Siberian Kyrgyz region of Yenisei in 1272, and before that year as well. He also sent them farming equipment and oxen. Tanguts, Khitans, and Han Chinese were sent to take care of gardens and fields in the depopulated and sacked city of Samarkand, where only 25% of the original 100,000 households survived the Mongol sacking, and Han Chinese artisans were "everywhere" in the ruined city, as witnessed on 3 December 1221. They managed to rehabilitate and reconstruct the city, since Samarqand was praised as a productive flourishing area before at least 1225, when the Khitan Yelu Chucai came there. Mongke sent Chang De to Hulagu in 1259. He went across Central Asia. He said, "numerous Chinese growing wheat, barley, millet, and thergrains" lived around Lake Qizilbash and the Ulungur river in north Dzungaria and the cities of Almaliq and Tiermuer Chancha had many Han Chinese from Shaanxi in the Ili river valley. He said, "the Muslim populace herehas become mixed with the Chinese and over time, their customs have gradually come to resemble those of the Middle Kingdom." During Mongke's rule in the 1250s in Iran in the 13th century, Iran received thousands of Han Chinese farmers. Han Chinese were the plurality in the Iranian Azerbaijan city of Khoy as of 1340, as testified by Mustawfi. Han Chinese in Khoy and Tabriz in Iranian Azerbaijan were originally sent to Marv by the Mongols before being sent to the Iranian Azerbaijani cities, as recorded by Rashid al-Din.

Rashid al-din said that the Chinese millet grain known as tuki was brought by Han Chinese first to Marv in Turkmenistan and then to Iranian Azerbaijan in Khoy and Tabriz. Later, Han Chinese were reported to be the most significant ethnicity generations later, in Khoi around 1340, when Mustawfi wrote about them. Rashid al-din wrote it in 1310. And local Muslims in Almalik lived with Han Chinese and Han Chinese were employed as guards and millet, barley, and wheat farmers around Beshbalik and worked in Samarkand as seen in 1259 by Liu Yu. Wheat and hemp were grown next to mud huts near the Kerulun river by Han Chinese farmers in 1247 near Karakorum, as seen by Zhang Dehui. Han Chinese made up 70% of herders in Mongolia, as seen by Xuting and Peng Daya. Siberia's Upper Yeniesei area, Samarkand, and western Mongolia all had Han Chinese craftsmen, as seen by Li Zhichang in 1221–1222. He visited Balkh, Samarkand, and Tashkent when he went to Central Asia and Mongolia from Shandong.

The Tabriz-based Rob'-e Rashidi and the Maraghe observatory in Ilkhanid Iran had scientists and scholars of Chinese origin. The "Book of Precious Presents or the Medicine of the Chinese People" (Tansuq-name ya tebb-e ahl-e Kheta) was translated by people working under Rashid-al-Din Fazl-Allah to Persian from Chinese and it was about Chinese medicine.

Rashid al-Din wrote about Chinese culture and history. Oljeitu's birth was witnessed by Rashid al-Din. The Sunni convert Jew Rashid al-Din was executed after the Ilkhanate became Shia.

Han Chinese were sent to the Upper Yenisei valley as weavers, into Samarkand and Outer Mongolia as craftsmen, as noticed by Ch'ang-ch'un in 1221-22 when he travelled to Kabul from Beijing and they moved to Russia and Iran. The Euphrates and Tigris basins were irrigated by Chinese hydraulic engineers and in 1258, at the siege of Baghdad, one of Hulagu Khan's generals was Han Chinese. Because of the Mongols, Chinese influenced architecture, music, ceramics, and Persian miniatures in the Golden Horde and Il-khan. Han Chinese, Mongols, Uighurs, Venetians, and Geonese all lived in Tabriz, where paper money was introduced and movable type printing and wood engraving as well as paper money, printed fabrics, and playing cards spread from China to Europe due to the Mongols. Wood engraving which was Chinese was mentioned in the 1313 book "Treasure of the Il-khan on the Sciences of Cathay", which was about Chinese medicine and translated by Rashid al-Din. The Mongols brought the Chinese idea of paper currency to Iran in 1294 where the name of the currency, chaw, was taken from the Chinese word Chao.

During the Mongol-Yuan period, some historians claim Persian was the ''lingua franca'' of Central Asia, and many Persians and Central Asians migrated to China. There was a large Persian community in China, especially among Chinese Muslims, and claim that Persian was one of the official languages of the Yuan dynasty, alongside Chinese and Mongolian. However, other historians challenge that claim and say Turkic languages, primarily Old Uyghur, were the auxiliary secondary language of the Yuan dynasty after the Mongol language and Chinese language and that Turkic languages were also the lingua franca of Mongol-ruled Central Asia, saying that Persian was not an official language of the Yuan.

The Chinese Yuan and Persian Ilkhanate enjoyed close relations, with nearly annual diplomatic exchanges between the two.

In 1289, Kublai Khan established a Muslim university in Beijing. Persian works were translated en masse into Chinese, some of which are preserved today by the Peking University Library. Many tombstones and archaeological tablets found in China are also probably written in the Perso-Arabic script.

China exported astronomical tools and discoveries, printing, paper money, sancai, and porcelain to Iran. Porcelain particularly grew popular among Persians.

Ming dynasty

The famous Maragheh observatory in Maragheh, Iran, is also known to have had some Chinese astronomers working there alongside Iranian astronomers, and some Iranian astronomical instruments were also being used by astronomers in China. Safavid Iranian art was also partly influenced by Chinese art to an extent. Shah Abbas had hundreds of Chinese artisans in his capital Esfahan. Also, 300 Chinese potters produced glazed tile buildings, and hundreds of others produced metalwork, miniature paintings, calligraphy, glasswork, tile work, and pottery. From E. Sykes's "Iran and Its People": "Early in the seventeenth century, Shah Abbas imported Chinese workmen into his country to teach his subjects the art of making porcelain, and the Chinese influence is very strong in the designs on this ware. Chinese marks are also copied, so that to scratch an article is sometimes the only means of proving it to be of Persian manufacture, for the Chinese glaze, hard as iron, will take no mark."

Of the Chinese Lin family in Quanzhou, Lin Nu, the son of Lin Lu, visited Hormuz in Persia in 1376, married a Persian or an Arab girl, and brought her back to Quanzhou. Lin Nu was the ancestor of the Ming dynasty reformer Li Zhi.

Notable Chinese Muslims who undertook the task of translation of Persian into Chinese include Chang Zhimei (medicine) and Liu Zhi. Although Persian was still spoken among some Muslim communities, due to decreased contact with the Middle East, language use declined.

Ming navy general Zheng He came from a Muslim family and sailed through much of the Old World, including India, Persia, Arabia, and Africa. In his wake, he left many relics, including the Chinese-Persian-Tamil Galle Trilingual Inscription, praising the Buddha, Allah, and Vishnu, respectively, in the three languages.

The Timurid empire wrote its letters to the Ming dynasty in Persian.

Qing dynasty

By the Qing, although hardly anyone in the court was fluent in Persian, in madrasas, Persian was still studied. In particular, the works of Sadi, Abd-Allāh Abū Bāker, Ḥosayn b. ʿĀlem Ḥosaynī, etc. were taught in said madrasas.

Modern China

Diplomatic links between China and Iran have been maintained into the 20th and 21st centuries with the formation of both the People's Republic of China and the Islamic Republic of Iran, in 1949 and 1979, respectively.

In the 1950s, Iran's alignment with anti-communism, its relationship with the Western countries, and its recognition of the Republic of China put it at odds with the PRC. After the Iranian Revolution, the hostile relationship between the Western countries and Iran contributed to increased ties with the PRC. The two countries grew closer during the Iran-Iraq War because China was an important source of arms for Iran.

In July 2019, Iran approved visa-free travel for all Chinese citizens, including those in Hong Kong and Macau, with China being one of twelve countries to have direct visa-free access to Iran.

In June 2020, Iran was one of 53 countries that backed the Hong Kong national security law at the United Nations Human Rights Council. The relationship between both countries includes also soft-power and digital diplomacy.

In March 2021, the two countries signed a 25-year cooperation agreement.

In February 2023, Iranian President Ebrahim Raisi visited China in the first such visit by an Iranian leader to China in more than twenty years. On March 10, 2023, Iran and Saudi Arabia announced that they would normalize their relations, in a deal brokered by China.

Economy

After the JCPOA was signed in July 2015, China and Iran agreed to expand trade relations to $600 billion in ten years from January 2016, on the occasion when Chinese leader Xi Jinping paid Hassan Rouhani a state visit. This constitutes an increase of over 1,000%. The agreement was concordant with the One Belt, One Road framework. A total of 17 agreements were signed, including one which relates to the Iranian nuclear program. The Chinese will help connect Tehran with Mashhad via their high-speed rail technology.

Oil and gas

One of the main pillars of the relationship is oil and gas. China switched to petroleum primarily to move its energy supply from coal. There was a rapid increase in oil importation from 1974 into the 1990s.Dorraj, Manochehr and Currier, Carrie L (2008). "Lubricated with Oil: Iran-China Relations in a Changing World" '' Middle East Policy'' In 2011, approximately 10% of China's oil imports were from Iran. Approximately 80% of China's total imports from Iran are oil and the rest are mineral and chemical products. Because of this reliance on Iranian oil and gas, China is now investing in the modernization of Iran's oil and gas sector to secure access to the resource. The China National Petroleum Corporation (CNPC) was granted an $85 million contract to drill 19 wells in the natural gas fields in Southern Iran and signed another similar $13 million contract. Then, again in 2004, an agreement was reached where China would import 270 million tons of natural gas over 30 years from South Par fields, which are the richest natural gas fields in the world, for $70 billion. Another Chinese company, Sinopec Group, gets half-share in Yardarvaran oil fields, worth about 100 billion for the purpose of exploration.Vivienne Walt (2005). "Iran Looks East" ''Fortune'' Later in 2007, CNPC signed a $3.6 billion deal to develop offshore gas fields in Iran and then signed another $2 billion contract to develop the northern Iranian oil field near Ahvaz. Not only is China helping to develop the oil and gas sector, but China supports Iran's ambitions to bring Caspian Sea oil and gas to Southern Iranian ports through pipelines so the resources can be exported to Europe and Asia. Iran relies upon its oil sales to China to ensure its fiscal well-being. China also sells gasoline to Iran despite international pressures that have halted Iran's ability to get gasoline from other suppliers.Erica Downs & Suzanne Moloney (2011). "Getting China to Sanction Iran" ''Foreign Affairs''

China considers Iran a permanent partner for its exports and a source of its growing energy demand. In March 2004, Zhuhai Zhenrong Corporation, a Chinese state-run company, signed a 25-year contract to import 110 million metric tons of Liquefied Natural Gas (LNG) from Iran. This was followed by another contract between Sinopec and Iran LNG, signed in October of the same year. The deal, worth $100 billion, adds an extra 250 million tons of LNG to China's energy supply, to be extracted from Iran's Yadavaran field over a 25-year period. In January 2009, Iran and China signed a $1.76bn contract for the initial development of the North Azadegan oil field in western Iran. In March, the two countries struck a three-year $3.39 billion deal to produce liquefied natural gas in Iran's mammoth South Pars natural gas field. Because of its limited refining capacity, Iran imports one-third of its refined products, such as petrol, from China.

In 2011, the group Green Experts of Iran reported that Beijing and Tehran had signed a deal that would give China exclusive rights to several Iranian oil and natural gas fields through 2024, including rights to build necessary infrastructure there. In return, China promised to treat any foreign attack against these regions as attacks against its own sovereign territory, and will defend them as such. China would need no prior permission from Iran's government to maintain and increase its military presence in the country, and would control the movement of Iranians in and out of these territories. This agreement was the basis for PLA General Zhang Zhaozhong stating, “China will not hesitate to protect Iran even with a Third World War.”

China has been Iran's crude oil sink since the JCPOA was signed. In 2017, 64% of an export total of $16.9 billion with China was crude oil.

Trade

During the Cold War, there were unofficial trade relations between Iran and China that have steadily increased over time. Trade reached $1.627 billion in the 1980s and $15 billion in 2007. In 2001, the volume of trade between Iran and China stood at roughly $3.3 billion, and in 2005, the volume of China-Iranian trade hit $9.2 billion. Iran's Deputy Minister of Commerce Mehdi Ghazanfari speculated that trade exchanges between Iran and China would exceed $25 billion in 2008.

In 2005, exports from China represented 8.3% of the total import market in Iran, giving China the second largest share of the market after Germany. China's exports to Iran have experienced particularly rapid growth in the past five years, with China replacing Japan as the world's second largest exporter to Iran. Iran's imports from China rose by 360% between 2000 and 2005. China is now responsible for about 9.5% of all Iranian imports. In 1988, the Iranian market opened up to Chinese industry when the PRC began economic restructuring.

Once profitable trade relations were established, the PRC invested in Tehran's subway systems, dams, fishery, and cement factories while Iran helped supply China with the highly desired minerals of coal, zinc, lead, and copper. Trade between the two states also included power generation, mining, and transportation equipment, along with arms and consumer goods such as electronics, auto parts, and toys. Iran is full of Chinese products and cars.

Iran–China trade value reached $45 billion in 2011 and was expected to increase to $50 billion by 2012.

Ali Akbar Salehi, Iran's former representative to the International Atomic Energy Agency, said that the two countries "mutually complement each other. They have industry and we have energy resources".

In January 2023, the Overseeing Chief of the Chabahar Free Zone Organization Amir Moghaddam reported that the primary holder dispatch leaving from China docked at Iran's key harbor of Chabahar, marking the foundation of the direct coordinate shipping line between China and Iran's southeastern seaport. He said that Chinese ships already emptied in Bandar Abbas, the capital city of the southern area of Hormuzgan, with their cargo, at that point, being exchanged to Chabahar in Sistan-Baluchistan Territory by means of little ships. With the foundation of the coordinated shipping line between China and Chabahar, cargoes are conveyed ten days prior, whereas fetched of stacking and emptying is decreased by 400 dollars per holder, the official clarified.

In 2023 the volume of Iran's export to China was $4.59B. Iran mainly exported to China ore, slag and ash (29.5%), plastic and articles of steel or iron (27.5%) and organic chemical (15.9%).

The volume of Chinees export to Iran in 2023 was $10B. China mainly exported to Iran machinery, mechanical appliances and parts (22.4%), electrical machinery and electronics (15.5%), cars, tractors, and trucks (24.9%).

As of 2025, Iran's largest trading partner is China.

Infrastructure

Line 5 of the Tehran metro began operating in 1999 and was Iran's first metro system. The line was constructed by the Chinese company NORINCO.

New Silk Road

As of 2019, Iran had signed onto Chinese leader Xi Jinping's signature One Belt One Road plan, and Iran is considered to be a key part of China's geopolitical ambitions in central Asia and the Middle East, sometimes described in terms of a new Great Game.

While cargoes are usually shipped between China and Iran by ship, it is also possible to travel between the two countries by train, via Kazakhstan and Turkmenistan (see Eurasian Land Bridge). In 2016, the first direct container train between Yiwu (Zhejiang Province) and Tehran made its way across Asia in 14 days. This is supposed to be the beginning of regular container train service along this route.

Iranians and Chinese are currently renovating rails to connect Ürümqi to Tehran as well as connect Kazakhstan, Kyrgyzstan, Uzbekistan, and Turkmenistan (also see Five-nations railway, Afghanistan–China relations). In another 2016 test run, it took 12 days to deliver freight from Shanghai to Tehran, whereas it would have taken 30 days by sea.

In May 2018, China planned to build a new freight train line with Iran. In 2020, a leaked document showed that a 25-year strategic partnership would be implemented between the two countries, in which China would invest in Iranian infrastructure, transport, and seaports. In exchange, Iran would provide a heavily discounted regular supply of its oil. Above all, the reasons for the timing of this agreement is the rivalry between the US, the main opponent of Iran, and China, the main supporter of Iran, played a major role in taking the step of signing the agreement.

Politics

Open mutual support is seen in Iran's support of the action at Tiananmen Square and Chinese condemnation of the United States' attack on an Iranian passenger plane, among other things.

Even Chinese state-run news agencies upheld the validity of the internationally controversial election and ultimately attributed any problems that day to terrorists and vandals. They deliberately left out images of Iranian security forces brutalizing the protesters.

Military

China is believed to have helped Iran militarily in the following areas: conducting training of high-level officials on advanced systems, providing technical support, supplying specialty steel for missile construction, providing control technology for missile development, and building a missile factory and test range. It is rumored that China is responsible for aiding in the development of advanced conventional weapons, including surface-to-air missiles, combat aircraft, radar systems, and fast-attack missile vessels.

It was not until the 1990s that the relationship between China and Iran came under close scrutiny by the United States. From this scrutiny, it became known that China was using North Korea to traffic arms during the Iran-Iraq war to avoid antagonizing the West, but later cut out the middle man. In the years of 1984–1986, about $1–2 billion worth of arms sales occurred.Dennis Van Vranken Hickley (1990). "New Directions in China's Arms for Export Policy: Of China's Military Ties with Iran" '' Asian Affairs'' And then in 1986, Iran obtained Chinese-made anti-ship surface-to-surface missiles that posed a threat to Persian Gulf shipping. In possessing these missiles, Iran is able to control the Strait of Hormuz and all of the naval trade to and from the Gulf countries.

In later inquiries, it was discovered that China sold Iran precursor and dual-use chemicals and the technology and equipment needed to use them. In 1996, the Washington Post reported that China was supplying chemical weapons plants in Iran that were destined for the Army. Arms exports began to steadily decline in the 1990s yet China engaged in $400 million worth of arms transfer agreements with Iran. Sales increased to $600 million from 1997 to 2000. On average, it is estimated that China has made $171 million per year in arms exports to Iran since 1982.Therese Delpech (2006). ''Iran and the Bomb: The Abdication of International Responsibility''. Columbia University Press

China and Iran held their first joint naval drill in 2017. These exercises focused on anti-piracy and search-and-rescue operations.

After coming to office in 2021, Iranian President Ebrahim Raisi pursued a "look east" policy to deepen ties with China and Russia. Tehran joined the Shanghai Cooperation Organisation in September 2021. In January 2022, Iran, China, and Russia held their third joint naval drills in the northern Indian Ocean. The three countries started joint naval drills in 2019 in the Indian Ocean and the Sea of Oman area. The purpose of this drill is to strengthen security and its foundations in the region, and to expand multilateral cooperation between the three countries to jointly support world peace, maritime security, and create a maritime community with a common future.

Nuclear technology

Nuclear cooperation began in the 1980s when China helped build a research reactor and supplied four other research reactors. Continued aid came in the form of helping Iran construct a uranium hexafluoride enrichment plant near Isfahan and the resumption of construction on a nuclear power plant at Bushehr that was left uncompleted by the French and Germans. In 1991, nuclear exports to Iran were discovered by the International Atomic Energy Association, which contained three types of uranium. A 1990 covert nuclear agreement was also discovered. This discovery was followed by an unprecedented nuclear cooperation agreement in 1992. The agreement was signed despite U.S. protests to have China limit its nuclear cooperation with Iran.

Direct nuclear cooperation has ended, but there is speculation over whether there remains indirect nuclear cooperation. In 2005, seven Chinese firms were suspected of selling nuclear weapons technology and all 7 had sanctions placed upon them. Those firms were banned from trading with the United States for two years. There also continues to be Chinese nuclear experts, scientists, and technicians present in Iran.

In 2015, China was part of the Iran nuclear deal framework. China opposes Iran's possible production and possession of nuclear weapons but does not see the urgency to stop it.

After the US withdrew from the Joint Comprehensive Plan of Action (JCPOA), China sought to preserve the JCPOA. China emphasized that all parties should return to the JCPOA. It worked with the remaining signatories (Russia, France, Germany, and the United Kingdom) in an effort to develop avenues such as Instrument in Support of Trade Exchanges which might result in Iran's continued compliance and facilitate legitimate trade with Iran amid the US-imposed sanctions on Iran.

On 16 Nov. 2021, United States President Joe Biden and Chinese President Xi Jinping talked about their positions in the resumption of negotiations with Iran on reviving the 2015 nuclear deal.

The Ministry of Foreign Affairs of the PRC characterizes the US actions in withdrawing from the JCPOA and imposing sanctions on Iran as "unilateral bullying" and states that the US should "immediately correct its wrongdoings and lift these illegal sanctions."

China's government has raised concern about Iran's increase in stockpiling and uranium enrichment following the US withdrawal from the JCPOA.

In June 2025, China's ambassador to the UN, Fu Cong, condemned Israeli strikes on Iran.

UN sanctions

At first Iran did not originally support China's bid for United Nations membership but did not veto. It wasn't until 1969 that Iran displayed open support for China's membership. Now, Iran relies on China's membership, and especially Chinese veto power on the Security Council, to protect it from US-led sanctions.

China is known for its preference of diplomacy over sanctions. This tradition includes China's (along with Russia's) opposition to UN sanctions against Iran. In 1980, China refused to support the UN arms embargo against Iran and further abstained from voting on US sanctions against Iran.

Only in 2010, under US pressure, did China join Russia to support the UN sanctions on Iran.

In 2018, the US ordered Canada to arrest and detain Meng Wanzhou, CFO of Huawei, for 'illegally dealing with' and allegedly violating sanctions against Iran.

Ideology

On 1 June 1920, a friendship agreement was signed between the Beiyang government and Qajar Persia. Ratifications were exchanged on 6 February 1922, with effect on the same day. Official diplomatic relations were established in 1937, with Li Tieh-tseng serving as ambassador representing the Republic of China. Prior to 1971, an unofficial relationship existed out of necessity. From this emerged the current relationship. The first Iranian embassy was formed in December 1973 and Abbas Aram was appointed to the post, becoming the first Iranian diplomat to serve in China, though the first embassy opened in 1942. The Shah visited Taiwan to meet the President of China Chiang Kai-shek in 1958. In 1971, Imperial Iran supported Red China's bid for a permanent seat in the United Nations General Assembly Resolution 2758 and it voted in favour to admit Beijing and replace Taipei. China was invited to the 2,500-year celebration of the Persian Empire. Iran recognized the People's Republic of China in 1971 with Chinese Communist Party chairman and Chinese Premier Hua Guofeng was one of the last foreign leaders to visit the Shah of Iran, before he was overthrown in 1979. In the 1980s, the shared ideological themes of anti-imperialism and third world solidarity helped solidify the relationship, but they became allies as a way to counterbalance the Soviet Union and the United States during the Cold War. When the USSR signed the Soviet-Indian friendship treaty, the relationship became a way to counter increasing Russian influence in the Persian Gulf. But there remained some distance between Mao's regime and that of the Shah because of ideology. The Shah was friendly towards the United States and Mao was a communist. The Shah also feared that the relationship could rally his communist opposition. Once the Shah was overthrown during the Islamic Revolution, China quickly recognized the new government on 14 February 1979. China was put into a difficult situation during the Iran–Iraq War in 1980 since China was allied with both nations. China was able to remain outside of the conflict and push for a peaceful resolution to the conflict.

Since Iran no longer recognizes the ROC, now residing in Taiwan, its representation is held by the Commercial Office of Taipei in Dubai, UAE.

China has been at times careful in its deals with Iran to avoid antagonizing its own relationship with the U.S. and Israel. China's approach toward the Israel-Iran conflict is to put economics ahead of political, ideological, or humanitarian interests and sympathies, and it seems China has found a balance on how to work well with the 2 enemies.

The cooperation emerges partly from Chinese and Iranian recognition as fellow heirs to great civilizations and because Iran has emerged as the regional leader in the Middle East. While there is also a shared distrust of the United States' government and its interests, many young Chinese and Iranians at the same time admire certain aspects of American society and culture. There is also Iranian admiration for China's rapid economic growth, and for the most part, their economic contributions to Iran are appreciated and respected.

Some analysts argue that Iran can use its links with China to build more links across Asia while remaining insulated from potential U.S. attack.

Beijing has generally supported the Iran-backed government of Bashar al-Assad in Syria, joining Russia in vetoing several U.N. resolutions condemning Assad's actions in the Syrian civil war, and strongly opposing Western interference in the conflict, arguing that outside intervention would further worsen and complicate the situation. It has also allegedly been increasing military links with Syria in recent years, albeit in a more limited sense than Moscow, partly because of the presence of Uighur militant rebels on the side of the Syrian rebels.

In April 2015, China stated that Iran had been officially accepted as a founding member of its newly founded Asian Infrastructure Investment Bank, with the latter owning 15,808 shares. There has also been recent discussion for Iran to eventually join the Shanghai Cooperation Organisation, of which it is currently an observer state, as a full member.

In 2016, Chinese leader Xi Jinping announced his support for Iran's full membership in SCO during a state visit to Iran.

In July 2019, UN ambassadors from 50 countries, including Iran, have signed a joint letter to the UNHRC defending China's treatment of Uyghurs and other Muslim minorities in the Xinjiang region.

In January 2020, China condemned the assassination of Qasem Soleimani, with the Chinese Foreign Minister Wang Yi alleging that the targeted killing of an Iranian general in Iraqi territory by the United States was in violation of international law.

In June 2020, Iran was one of 53 countries that backed the Hong Kong national security law at the United Nations.

Former lawmaker Ali Motahari tweeted in August 2020 how it was a failure for the Islamic republic that the US protested against "China’s treatment and torture of Muslims from Xinjiang to eradicate the Islamic culture from that region" while Iran remained silent due to of its economic needs; he added that " Chinese Muslims are no different from Yemeni or Palestinian Muslims". Conservative lawmakers and news editors defended China by saying the country just had problems with Wahabi Takfiri ideology, not Islam in general. In a 2021 meeting with a group of university students, former President Mahmoud Ahmadinejad wondered why Iran was silent on China's " Uyghur genocide".

In 2021, the Iranian embassy in China published a series "An Iranian Diplomat's Xinjiang Diary" which related observations of religious respect in Xinjiang and contended that allegations of forced labor in Xinjiang were false.

In late 2022, Iranian Foreign Minister Hossein Amir-Abdollahian was reacting to a joint statement issued by China and states of the Gulf Cooperation Council, which called for peaceful resolution of the islands dispute with the United Arab Emirates. Iran conveyed its "strong discontent" with the GCC-China statement, and China later expressed respect for Iran's territorial integrity.

Following the April 2024 Iranian strikes against Israel, PRC Foreign Minister Wang Yi had a call with Iranian counterpart Hossein Amir-Abdollahian where Wang reiterated Iran's assertion that its attack was a "limited" action taken in self-defense, adding he believed Iran could "handle the situation well and spare the region further turmoil". In contrast, ROC Taiwanese President Tsai Ing-wen and Foreign Minister Joseph Wu condemned Iran's attack.

Society

There are several historic social connections between the two states. Although the two societies psychologically identify with one another because they both share the national pride and historical identity that comes along with being the descendants of two great empires and modern successor-states to ancient civilizations, there was limited interaction after the Chinese Communist Revolution in 1949. Social interactions improved after the 1960s.

According to '' The Diplomat'' in January 2021, anti-Chinese sentiment in Iran was increasing in due to China's economic activity and social differences between the two countries. A September 2021 poll done by the Center for International and Security Studies at Maryland had 42% of Iranian respondents holding an unfavorable view of China compared to 58% holding a favorable view. Gallup polling for 2023 had 51% of Iranians approving of China's leadership which was higher than approval of their own (43%), Russia's (31%), and USA's leadership (10%); the results had been consistent with Gallup data from 2021 and 2022 on Iranian approval of Chinese and American leadership.

About 2,000 Chinese live in Tehran as of 2005, and 70 Chinese companies have relocated to Iran.

Intermarriage

Iran and China have a long history of intermarriages, since at least the Tang. Immigrant communities of Persian Muslims in China intermarried with local women, forming part of the modern Hui people. At the same time, Persian women also intermarried with Chinese men: see Lin Nu, Liu Chang (Southern Han), Wang Zongyan (married Li Shunxian), and the Zhengde Emperor. Mixed descendants include Li Zhi (philosopher) and Hu Dahai.

Aurel Stein discovered 5 letters written in Sogdian, known as the "Ancient Letters", in an abandoned watchtower near Dunhuang in 1907. One of them was written by a Sogdian woman named Miwnay who had a daughter named Shayn, and she wrote to her mother Chatis in Sogdia. Miwnay and her daughter were abandoned in China by Nanai-dhat, her husband who was also Sogdian like her. Nanai-dhat refused to help Miwnay and their daughter after forcing them to come with him to Dunhuang and then abandoning them, telling them they should serve the Han Chinese. Miwnay asked one of her husband's relatives, Artivan, and then asked another Sogdian man, Farnkhund, to help them, but they also abandoned them. Miwnay and her daughter Shayn were then forced to become servants of Han Chinese after living on charity from a priest. Miwnay cursed her Sogdian husband for leaving her, saying she would rather have been married to a pig or dog. Another letter in the collection was written by the Sogdian Nanai-vandak, addressed to Sogdians back home in Samarkand informing them about a mass rebellion by Xiongnu Hun rebels against their Han Chinese rulers of the Western Jin dynasty, informing his people that every single one of the diaspora Sogdians and Indians in the Chinese Western Jin capital Luoyang died of starvation due to the uprising by the rebellious Xiongnu, who were formerly subjects of the Han Chinese. The Han Chinese emperor abandoned Luoyang when it came under siege by the Xiongnu rebels and his palace was burned down. Nanai-vandak also said the city of Ye was no more as the Xiongnu rebellion resulted in disaster for the Sogdian diaspora in China.

Sogdians were called "Hu" (胡) by the Chinese during the Tang dynasty. Central Asian "Hu" women were stereotyped as barmaids or dancers by Han in China. Han Chinese men engaged in mostly extra-marital sexual relationships with them as the "Hu" women in China mostly occupied positions where sexual services were sold to patrons like singers, maids, slaves, and prostitutes. Southern Baiyue girls were exoticized in poems. Han men did not want to legally marry them unless they had no choice, such as if they were on the frontier or in exile, since the Han men would be socially disadvantaged and have to marry non-Han. The task of taking care of herd animals like sheep and cattle was given to "Hu" slaves in China.

Culture

Chinese culture has influenced Iran's literature, television, and cultural events. An example of this influence is the opening of Chinese restaurants in Tehran. China wants to create a positive image of itself, in order to uphold existing and future relations. Iran's similar attempts of cultural influence inside of China have been received with open arms. In addition, China opened the Confucius Institute at the University of Tehran and at the University of Mazandaran.

Literature

Li Shunxian is a Persian-Chinese woman who wrote celebrated Chinese poetry during the Tang dynasty.

Ha Dechen and Wang Jingzhai helped translate Persian literature into Chinese. Sadi's works are particularly well-known and have been broadcast on Chinese media.

Linguistics

Mainly through Silk Road trade, Chinese borrowed Middle Persian words for exotic commodities. Oddly, these loanwords are typically themselves loans from a pre-Iranian substrate, e.g. Elamite or BMAC:

''Huihuihua'' is a dialect of Chinese with more Persian and Arabic words.

The Galle Trilingual Inscription is associated with the voyages of Zheng He.
