History

Drawing the line

Early British efforts to create a boundary in this sector were triggered by their discovery in the mid-19th century that Tawang, an important trading town, was Tibetan territory. In 1873, the British-run Government of India drew an "Outer Line," intended as an international boundary. This line follows the alignment of the Himalayan foothills, now roughly the southern boundary of Arunachal Pradesh. Britain concluded treaties with Beijing concerning Tibet's boundaries with Burma and Sikkim. However, Tibet refused to recognize the boundaries drawn by these treaties.

British interest in the borderlands was renewed when the Qing government sent military forces to establish Chinese administration in Tibet (1910–12). A British military expedition was sent into what is now Arunachal Pradesh

 and the North East Frontier Tract was created to administer the area (1912). In 1912-13, this agency reached agreements with the tribal leaders who ruled the bulk of the region. The Outer Line was moved north, but Tawang was left as Tibetan territory. After the fall of the Qing dynasty in China, Tibet expelled all Chinese officials and troops, and declared itself independent (1913).

This map lacked any initials or signatures from the Chinese plenipotentiary Ivan Chen; however Chen had signed an earlier, similar draft of it from 27 April 1914.
Both drafts of this small scale map extend the identical red line symbol between "Inner Tibet" and China further to the southwest, approximating the entire route of the McMahon Line, and thus dead ending near Tawang at the Bhutan tripoint.

.

The far more detailed eight miles to the inch McMahon Line map of 24–25 March 1914 is signed only by the Tibetan and British representatives. This map and McMahon Line negotiations were both done without Chinese participation. After Beijing repudiated Simla, the British and Tibetan delegates attached a note denying China any privileges under the agreement and signed it as a bilateral accord.

Britain attempts to enforce line

Simla was initially rejected by the Government of India as incompatible with the 1907 Anglo-Russian Convention. C.U. Aitchison's A Collection of Treaties, was published with a note stating that no binding agreement had been reached at Simla. The Anglo-Russian Convention was renounced by Russia and Britain jointly in 1921, but the McMahon Line was forgotten until 1935, when interest was revived by civil service officer Olaf Caroe

A volume published earlier was recalled from libraries and replaced with a volume that includes the Simla Accord together with an editor's note stating that Tibet and Britain, but not China, accepted the agreement as binding. The replacement volume has a false 1929 publication date.

, Tibet protested. However, Lhasa raised no objection to British activity in other sectors of the McMahon Line. In 1944, NEFT established direct administrative control for the entire area it was assigned, although Tibet soon regained authority in Tawang. In 1947, the Tibetan government wrote a note presented to the Indian Ministry of External Affairs laying claim to Tibetan districts south of the McMahon Line. In Beijing, the Communist Party came to power in 1949 and declared its intention to "liberate" Tibet. India, which had become independent in 1947, responded by declaring the McMahon Line to be its boundary and by decisively asserting control of the Tawang area (1950–51).

 offered to accept the McMahon Line in 1956 , but only in the context of border negotiations as equals, because simply accepting the British boundary would leave the stigma of the unequal treaty and hurt Chinese pride. But Nehru maintained his 1950 statement that he would not accept negotiations if China brought the boundary dispute up, hoping that "China would accept the fait accompli. In 1954, India renamed the disputed area the North East Frontier Agency.

 started openly advocating Tibetan independence. Nehru, seeking to quickly assert sovereignty in response, established "as many military posts along the frontier as possible", unannounced and against the advice of his staff. On discovering the posts, and already suspicious from the ruminations of the Indian press, Chinese leaders began to suspect that Nehru had designs on the region. In August 1959, Chinese troops captured an Indian outpost at Longju, three miles south of the McMahon Line according to the Geonames database (National Geospatial-Intelligence Agency

In 1984, India Intelligence Bureau personnel in the Tawang region set up an observation post in the Sumdorong Chu Valley just south of the highest hill crest, but a few kilometers north of the McMahon Line (the straight line portion extending east from Bhutan for 30 miles). The IB left the area before winter. In 1986, China deployed troops in the valley before an Indian team arrived. This information created a national uproar when it was revealed to the Indian public. In October 1986, Deng threatened to "teach India a lesson". The Indian Army

 visited China in 1988 and agreed to a joint working group on boundary issues which has made little apparent positive progress. A 1993 Sino-Indian agreement set up a group to define the LAC; this group has likewise made no progress. A 1996 Sino-Indian agreement set up "confidence-building measures" to avoid border clashes. Although there have been frequent incidents where one state has charged the other with incursions, causing tense encounters along the McMahon Line following India's nuclear test in 1998 and continuing to the present, both sides generally attribute these to disagreements of less than a kilometer as to the exact location of the LAC.
