evidence: Is Tawang, Home of Tibetan Buddhism’s 2nd Largest Monastery, China’s Next Territorial Target in India? [...] Tawang, historically, was part of Tibet as the most important frontier administrative unit of the government of Tibet before signing the Simla Convention in 1914. This convention demarcated the boundary between Tibet and the eastern Himalayan region of British India, finally drawing the McMahon Line as the border between Tibet and British India. It was here at the Simla Convention that the independent and sovereign state of Tibet legally ceded the Tawang region to British India. The region was later incorporated into what was formerly known as the North East Frontier Agency, including present-day Arunachal Pradesh and some parts of Assam.
