In June 1930, the Nyarong Lama and monks from Targye monastery seized possession of Nyarong monastery. The Beri chief then sought assistance from General Liu, whose troops took control of the area. The Targye monks responded by asking Lhasa to deploy the Tibetan border troops in Kham in their aid. The Tibetan governor-general sent a Tibetan force from Derge that engaged the Chinese and drove them out of Beri and large parts of Kanze District.
Between 1930 and 1932 a second Sino-Tibetan War was fought between the Tibetan Army and the provincial Chinese troops of Szechwan and Chinghai provinces. A Tibetan army invaded Szechwan and a low-level but brutal conflict lasted for almost two years. (...) After the establishment of a regular Tibetan Army in 1913 they received limited British military aid which continued on a small scale into the 1930s.
