Simla Accord (1914)

Simla Accord (1914)

The Simla Accord, or the Convention Between Great Britain, China, and Tibet, [in] Simla,[1] is a treaty concerning the status of Tibet negotiated by representatives of the Republic of China, Tibet and Britain in Simla in 1913 and 1914.
The Accord provided that Tibet would be divided into "Outer Tibet" and "Inner Tibet". Outer Tibet, which roughly corresponded to Ü-Tsang and western Kham would "remain in the hands of the Tibetan Government at Lhasa under Chinese suzerainty, but China would not interfere in its administration. "Inner Tibet", roughly, equivalent to Amdo and eastern Kham, would be under the jurisdiction of the Chinese government. The Accord with its annexes also defines the boundary between Tibet and China proper and between Tibet and British India (the latter became known as the McMahon Line).[1][2][nb 1] The latter boundary was later referred to as the McMahon Line.
China rejected the Accord and their plenipotentiary, Ivan Chen, withdrew on 3 July 1914. The British and Tibetan plenipotentiaries then attached a note denying China any privileges under the Accord and sealed it as a bilateral agreement the same day.[3][nb 2][4]
McMahon's work was initially rejected by the British government as incompatible with the 1907 Anglo-Russian Convention. This convention was renounced in 1921. The British began using the McMahon Line on Survey of India maps in 1937, and the Simla Accord was published officially in 1938.
