Soon after gaining independence in January 1948, the central government led by U Nu faced several armed rebellions. The most serious was the Chinese Nationalist KMT invasion of Shan State in 1950. Driven out by the Chinese Communist forces, Nationalist KMT armies planned to use the region east of the Salween River as a base from which to regain their homeland. In March 1953, the KMT forces, with US assistance, were on the verge of taking the entire Shan State and within a day's march of the state capital Taunggyi. The Burmese army drove the invaders east across the Salween, but much of the KMT army and their progeny have remained in the eastern Shan State under various guises to the present day. The Burmese army's heavy-handedness fueled resentment.
