Ma Bufang
Under orders from the Kuomintang government of Chiang Kai-shek, Ma Bufang repaired the Yushu airport in 1942 to deter Tibetan independence. Chiang also ordered Ma Bufang to put his Muslim soldiers on alert for an invasion of Tibet in 1942. Ma Bufang complied, and moved several thousand troops to the border with Tibet. Chiang also threatened the Tibetans with bombing if they did not comply.
