Liu Wenhui
In 1930, the Tibetan army invaded Garzê, capturing it without much resistance. However, in 1932, the Tibetan army withdrew after suffering defeats elsewhere at the hands of the warlord of Qinghai, Ma Bufang. Chinese warlord Liu Wenhui reoccupied Garzê, and signed an agreement with the Tibetans formalizing his control of the area east of the upper Yangtze, which corresponds roughly with eastern Kham.
