In Burma, the Wa live mostly in small villages near Kengtung and north and northeastwards close to the Chinese border, as well as a small area east of Tachileik. The Wa Special Region 2 of the Northern Shan State or Wa State was formed by the United Wa State Army (UWSA) and the remains of the former Burmese Communist Party rebel group that collapsed in 1989. The Wa State and the UWSA are in a fragile cease-fire agreement with the Burmese military government. They have been accused by Western governments of involvement in drug trafficking but have banned opium production since 2005 and have received United Nations aid in improving legitimate agriculture.
