In October 1947, the Nationalist government in Nanking informed the Indian Embassy of its wish to modify such agreements as were entered into between Great Britain and Tibet, including the Simla Agreement, 1914, that defined India’s frontier with Tibet. In the same month, the Dalai Lama’s government in Lhasa had also addressed a letter to India’s Prime Minister seeking the return of ‘all our indisputable Tibetan territories gradually included into India’, which included parts of modern-day Arunachal Pradesh, Ladakh, Darjeeling, Sikkim and Bhutan.
