佤邦
In 1989 the Wa authorities expelled the Burma Communist Party and negotiated a cease-fire with the then leader of Burma's military junta Khin Nyunt. They founded the United Wa State Army and United Wa State Party with a centralized command. In return for agreeing to the ban of poppy cultivation and opium production the region experienced a massive influx of international development aid. The Wa Special Region 2 was created within the northeastern Shan State, with its de facto capital in Pangkham.
