The 1954 Sino-Indian Agreement, also called the Panchsheel Agreement,[1] officially the Agreement on Trade and Intercourse Between Tibet Region and India, was signed by China and India in Peking on 29 April 1954. The preamble of the agreement stated the panchsheel, or the five principles of peaceful coexistence, that China proposed and India favoured. The agreement reflected the adjustment of the previously existing trade relations between Tibet and India to the changed context of India's decolonisation and China's assertion of suzerainty over Tibet. Bertil Lintner writes that in the agreement, "Tibet was referred to, for the first time in history, as 'the Tibet Region of China'".[2]
The agreement expired on 6 June 1962, as per the original term limit, in the midst of the Sino-Indian border tensions. It was not renewed. By October of that year, war broke out between the two sides.[3]
