Ma Bufang
Chiang had uneasy relations with the Tibetans. He fought against them in the Sino-Tibetan War, and he supported the Muslim General Ma Bufang in his war against Tibetan rebels in Qinghai. Chiang ordered Ma Bufang to prepare his Islamic army to invade Tibet several times, to deter Tibetan independence, and threatened them with aerial bombardment. After the war, Chiang appointed Ma Bufang as ambassador to Saudi Arabia.
