In August 1990, government officials began drafting a plan to end drug production and trafficking in Wa State. According to an interview with Wa officials in 1994, Bao Youyi (Tax Kuad Rang; also known as Bao Youyu) became wanted by the Chinese police for his involvement in drug trafficking. As a result, Bao Youxiang and Zhao Nyi-Lai went to Cangyuan Va Autonomous County of China and signed the Cangyuan Agreement with local officials, which stated that, "No drugs will go into the international society (from Wa State); no drugs will go into China (from Wa State); no drugs will go into Burmese government-controlled areas (from Wa State)." However, the agreement did not mention whether or not Wa State could sell drugs to insurgent groups.
