The Sino-Tibetan War (, lit. Kham–Tibet border dispute) was a war that began in 1930 when the Tibetan Army under the 13th Dalai Lama invaded Xikang and Yushu in Qinghai in a dispute over monasteries. Ma clique warlord Ma Bufang secretly sent a telegram to Sichuan warlord Liu Wenhui and the leader of the Republic of China, Chiang Kai-shek, suggesting a joint attack on the Tibetan forces. Their armies rapidly overwhelmed and defeated the Tibetan Army.
