Xikang

Xikang (formerly romanized as Sikang or Hsikang, or 'Kham to the west [of Sichuan]') was a nominal province formed by the Republic of China in 1939 on the initiative of prominent Sichuan warlord Liu Wenhui and retained by the early People's Republic of China. The former territory of Xikang is now divided between the Tibet Autonomous Region (TAR) and Sichuan province.

The idea behind Xikang province was to form a single unified province for the entire Kham region under direct Chinese administration, in effect annexing the western Kham region that was then under Tibetan control. Kham was entirely populated by Tibetan people called Khampas. The then-independent Tibet controlled the portion of Kham west of the Upper Yangtze River. The nominal Xikang province also included in the south the Assam Himalayan region (Arunachal Pradesh) that Tibet had recognised as a part of British India by the 1914 McMahon Line agreement. The eastern part of the province was inhabited by a number of different ethnic groups, such as Han Chinese, Yi, Qiang people and Tibetan, then known as Chuanbian (), a special administrative region of the Republic of China. In 1939, it became the new Xikang province with the additional territories belonging to Tibetan and British control added in. It was taken over by Chinese communist forces in 1949.
