Because of doubts concerning the legal status of the accord, the British did not put the McMahon Line on their maps until 1937, nor did they publish the Simla Convention in the treaty record until 1938. Rejecting Tibet's 1913 declaration of independence, China argued that the Simla Convention and McMahon Line were illegal and that Tibetan government was merely a local government without treaty-making powers. The British records show that the Tibetan government's acceptance of the new border in 1914 was conditional on China accepting the Simla Convention. Since the British were not able to get an acceptance from China, Tibetans considered the McMahon line invalid. Tibetan officials continued to administer

, but which were heavily influenced by Indian culture, further complicates the issue. India's claim line in the eastern sector follows its interpretation of the McMahon Line. The line drawn by McMahon on the detailed 24–25 March 1914 Simla Treaty maps clearly starts at 27°45’40"N, a trijunction between Bhutan, China, and India, and from there, extends eastwards. Most of the fighting in the eastern sector before the start of the war would take place immediately north of this line. However, India claimed that the ''intent'' of the treaty was to follow the main watershed ridge divide of the Himalayas based on memos from McMahon and the fact that over 90% of the McMahon Line does in fact follow the main watershed ridge divide of the Himalayas. They claimed that territory south of the high ridges here near Bhutan (as elsewhere along most of the McMahon Line) should be Indian territory and north of the high ridges should be Chinese territory. In the Indian claim, the two armies would be separated from each other by the highest mountains in the world. During and after the 1950s, when India began patrolling this area and mapping in greater detail, they confirmed what the 1914 Simla agreement map depicted: six river crossings that interrupted the main Himalayan watershed ridge. At the westernmost location near Bhutan north of Tawang, they modified their maps to extend their claim line northwards to include features such as Thag La ridge, Longju, and Khinzemane as Indian territory. Thus, the Indian version of the McMahon Line moves the Bhutan-China-India trijunction north to 27°51’30"N from 27°45’40"N. India would claim that the treaty map ran along features such as Thag La ridge, though the actual treaty map itself is topographically vague (as the treaty was not accompanied with demarcation) in places, shows a straight line (not a watershed ridge) near Bhutan and near Thag La, and the treaty includes no verbal description of geographic features nor description of the highest ridges.

In October 1967, another military duel took place at Cho La and ended on the same day. According to independent sources, the Indian forces achieved "decisive tactical advantage" and defeated the Chinese forces in these clashes. Many PLA fortifications at Nathu La were said to be destroyed, where the Indian troops drove back the attacking Chinese forces.

According to Indian media, the incursion included Chinese military helicopters entering Indian airspace to drop supplies to the troops. However, Chinese officials denied any trespassing having taken place. Soldiers from both countries briefly set up camps on the ill-defined frontier facing each other, but the tension was defused when both sides pulled back soldiers in early May.

Doklam: To Start at the Very Beginning
Previously, China had built a dirt road terminating at Doka La where Indian troops were stationed. They would conduct foot patrol from this point up till the Royal Bhutanese Army (RBA) post at Jampheri Ridge. The dispute that ensued post 16 June stemmed from the fact that the Chinese had begun building a road below Doka La, in what India and Bhutan claim to be disputed territory. This resulted in Indian intervention of China's road construction on 18 June, two days after construction began. Bhutan claims that the Chinese have violated the written agreements between the two countries that were drawn up in 1988 and 1998 after extensive rounds of talks.Manoj Joshi
Doklam, Gipmochi, Gyemochen: It's Hard Making Cartographic Sense of a Geopolitical Quagmire
The agreements drawn state that status quo must be maintained in the Doklam area as of before March 1959. It is these agreements that China has violated by constructing a road below Doka La. A series of statements from each countries' respective External Affairs ministries were issued defending each countries' actions. Due to the ambiguity of earlier rounds of border talks beginning from the 1890 Anglo-Chinese Convention that was signed in Kolkata on 17 March 1890, each country refers to different agreements drawn when trying to defend its position on the border dispute. Following the incursion, on 28 June, the Chinese military claimed that India had blocked the construction of a road that was taking place in China's sovereign territory.HT Corresponden

On 30 June, India's Foreign Ministry claimed that China's road construction in violation of the status quo had security implications for India. Following this, on 5 July, Bhutan issued a demarche asking China to restore the status quo as of before 16 June. Throughout July and August, the Doklam issue remained unresolved. On 28 August, India issued a statement saying that both countries have agreed to "expeditious disengagement" in the Doklam region. In 2019, India and China decided to coordinate border patrolling at one disputed point along the LAC.

Timeline

Boundary discussions

One of the first set of formal talks between China and India on the border were following Zhou Enlai's visit to India in 19–25 April 1960. Following this there were a further three sessions of talks, the "Official's" talks, between— 15 June-6 July 1960; 15 August-24 September 1960; and 7 November-12 December 1960. These discussions produced the ' Report of the Officials on the boundary question'. Boundary discussions have covered micro and macro issues of the dispute. At a local level, localised disputes and related events such as de-engagement and de-escalation are tackled. Wider overarching issues include discussion related to a package settlement versus sector-wise, clarification of the LAC and border and accordingly the exchange of maps, and delinking or linking the boundary dispute to other bilateral ties.

Package proposal

China made the so-called "package" offer in 1960, which again came to the table in 1980–85. As explained by former foreign secretary

Shyam Saran Shyam Saran (born 4 September 1946) is an Indian career diplomat. He joined the Indian Foreign Service in 1970 and rose to become the Foreign Secretary to the Government of India. Prior to his appointment as the Foreign Secretary he served as ...

, China "would be prepared to accept an alignment in the Eastern Sector, in general conforming to the McMahon Line, but India would have to concede Aksai Chin to China in the Western Sector ..For the Central Sector, the differences were regarded as relatively minor and manageable." In other words, China "offered to hold 26% of the disputed land". In 1985 China made modifications to the package— "the Indian side would have to make significant and meaningful concessions in the Eastern Sector... for which China would make corresponding but undefined concessions in the Western Sector". Additionally,

was brought up "as indispensable to any boundary settlement". These changes in the package proposal by China remained till at least 2015.

Linking border and other bilateral relations

During the first round of renewed talks between China and India in December 1981, China suggested maintaining the status quo on the border question, and in the meantime other relations could be normalized. By the fourth round in October 1983 the Indian negotiators agreed to normalization in other areas. This aspect of linking or de-linking border relations resurfaced in the

.

Legal positions

In the 1980s, during the beginning of talks between the two countries, India made it clear that it would not discuss the legal position of either side as it had already been documented in the 1960 Official's report.

Political initiatives

During the eighth round of talks in November, 1987, in the background of the Sumdorong Chu standoff, the negotiators on both sides came to a conclusion that apart from these bureaucratic level talks, a political move was needed.

Dispute management and resolution mechanism

Indian spokesperson for the Ministry of External Affairs stated in May 2020 that there were enough bilateral mechanisms to solve border disputes diplomatically. However, some critics say that these agreements are "deeply flawed".

Bilateral mechanisms

Bodies/mechanisms have been formed as per bilateral agreements to consult on the boundary question: Following the 1962 boundary war, official border talks started in December 1981. There were eight rounds of these talks, with the eight round being in 1987. In 1988, through a joint press communique, the border talks were formalized as the 'India-China Joint Working Group on the Boundary Question' (JWG). The JWG met 15 times, the final meeting being in 2005. In 2003 the Special Representatives Mechanism (SRM) was set up as per the 'Declaration on Principles for Relations and Comprehensive Cooperation'. In April 2005 another agreement mentioned that the JWG, the "India-China Diplomatic and Military Expert Group", and the "Special Representatives on the boundary question" would carry on with their work and consultations. Other than agreements directly related to the border, there have been numerous agreements that worked on other aspects of the bilateral relations such as a memorandum of understanding on military relations that was signed in 2006, that in turn affected the border situation.
