Simla Convention

The Simla Convention, officially the Convention Between Great Britain, China, and Tibet, was an ambiguous treaty on the status of Tibet, negotiated by representatives of the Republic of China, Tibet and Great Britain at Simla and Delhi during 1913 and 1914. It proposed dividing Tibet into Outer Tibet, which would stay under the Tibetan government at Lhasa with China holding suzerainty, and Inner Tibet, which would fall under Chinese jurisdiction. Its annexes also defined the boundary between Tibet and China proper and the one between Tibet and British India, the latter later known as the McMahon Line. All three parties initialled a draft on 27 April 1914, but China at once repudiated it, and a revised text signed on 3 July 1914 bore only the signatures of Britain and Tibet. The Government of India regarded it in 1915 as for the present invalid.
