The Battle of Chamdo (or Qamdo; ) occurred from 6 to 24 October 1950. It was a military campaign by the People's Republic of China (PRC) to take the Chamdo Region from a de facto independent Tibetan state. The campaign resulted in the capture of Chamdo and the annexation of Tibet by the People's Republic of China. Background Kham was a border region of Tibet. Prior to the establishment of the PRC, it roughly coincided with the Sikang Province under Kuomintang-led Republic of China. Its western half is known as Chamdo. The Khampa Tibetans and Lhasa Tibetans held each other in mutual contempt and dislike, with the Khampas in some cases hating Lhasa rule even more than Chinese rule, which was why the Khampas did little to resist Chinese forces as they entered eastern Kham and subsequently took over the whole of Tibet.

Ngabo refused the offer. Negotiations with Lhasa On 7 March 1950, a Tibetan government delegation arrived in Kalimpong to open a dialogue with the newly declared People's Republic of China and aimed to secure assurances that it would respect Tibet's "territorial integrity", among other things. The dialogue was delayed by a debate between the Tibetan, Indian, British and the PRC delegation over the location of the talks. The Tibetan delegation eventually met with the PRC’s ambassador General Yuan Zhongxian in Delhi on 16 September 1950. Yuan communicated a three-point claimed proposal that Tibet be regarded as part of China, that China be responsible for Tibet’s defense, and that China was
