boundary that ROC turned down. , 1950) Following the 1905
Batang uprising,
Qing China appointed
Zhao Erfeng as the Imperial Commissioner for the Sichuan-Yunnan Frontier. Zhao reduced all the autonomous native states in both the western and eastern Kham by 1910 and converted them into Chinese districts governed by magistrates. He signed an agreement with the Tibetan government setting the border between China and Tibet at
Gyamda. This paved the way for the formation of a Xikang province, proposed by Zhang's successor Fu Songmu. Following the
Wuchang Uprising in October 1911, which led to the downfall of the
Qing dynasty, the region subdued by Frontier Commissioners was established as the
Chuanbian Special Administrative District () by the newly founded Republic of China. In June 1930, eastern Kham (later Xikang) was invaded by the
army of Tibet, precipitating the
Sino-Tibetan War. With the district locked in internal struggles, no reinforcements were sent to support the
Sichuanese troops stationed here. As a result, the Tibetan army captured
Garzê and
Xinlong Counties without encountering much resistance. When a negotiated ceasefire failed, Tibetan forces expanded the war, attempting to capture parts of southern
Qinghai province. In March 1932, their force invaded Qinghai but was defeated by the local
Hui warlord
Ma Bufang in July, who routed the Tibetan army and drove it back to this district. The Hui army captured counties that had fallen into the hands of the Tibetan army since 1919. Their victories threatened the supply lines of the Tibetan forces in Garzê and Xinlong. As a result, part of the Tibetan army was forced to withdraw. In 1932
Liu Wenhui in cooperation with the Qinghai army, sent out a
brigade to attack the Tibetan troops in Garzê and Xinlong, eventually occupying them,
Dêgê and other counties east of the Jinshajiang River. The
1934 Khamba Rebellion led by the Pandatsang family broke out against the Tibetan government in Lhasa. The Khampa revolutionary leader
Pandatsang Rapga was involved. In January 1939, the
Chuanbian Special Administrative District officially became a province of the Republic, the
Hsikang Province. Kesang Tsering was sent by the Chinese to Batang to take control of Xikang, where he formed a local government. He was sent there for the purpose of propagating the
Three Principles of the People to the Khampa. In 1949, the
People's Liberation Army took control of Xikang. In 1955, eastern Xikang was merged into
Sichuan, and western Xikang came under the administration of the Preparatory Committee for the Tibet Autonomous Region. ==Administrative divisions==
