 According to Yu Shiyu, during China's resistance war against Japanese invasion, Chiang Kai-shek ordered the Chinese Muslim General Ma Bufang, Governor of Qinghai (1937–1949), to repair the Yushu airport in Qinghai Province to deter Tibetan independence.In May 1943, Chiang warned that Tibet must accept and follow the instructions and orders of the Central Government, that they must agree and help to build the Chinese-India [war-supply] road, and that they must maintain direct communications with the Office of the Mongolian and Tibetan Affairs Commission (MTAC) in Lhasa and not through the newly established "Foreign Office" of Tibet.He sternly warned that he would "send an air force to bomb Tibet immediately" should Tibet be found to be collaborating with Japan.
