Simla Convention(redirected from McMahon Line)
Also found in: Wikipedia.
an agreement concluded between McMahon, representing Great Britain, and Lonchen Shatra, representing local Tibetan authorities, on July 3, 1914, in the city of Simla, India. A British draft of the convention was discussed at an Anglo-Chinese-Tibetan conference in Simla in 1913 and 1914. In March 1914, during the conference, McMahon and Shatra exchanged secret letters and maps concerning a line demarcating the eastern part of the frontier between Tibet and British India. The line, which came to be known as the McMahon Line, was later entered on the maps appended to the British draft convention.
The Simla Convention obligated the Chinese government not to annex Tibet and not to send Chinese troops or civilians into Tibet. The Chinese representative, under pressure from the British, at first initialed the British draft convention but later never signed it. The Chinese government refused to recognize the Simla Convention.
