Wei Hsueh-kang, also known by various other names, is a Chinese-born business tycoon and drug trafficker wanted by the United States and Thailand for illegally trafficking drugs in New York and Southeast Asia's Golden Triangle. He is also a regional commander of the United Wa State Army, the armed forces of the de facto independent Wa State in Myanmar.

The United Wa State Army, abbreviated as the UWSA or the UWS Army, is the military wing of the United Wa State Party (UWSP), the de facto ruling party of Wa State in Myanmar. It is a well-equipped ethnic minority army of an estimated 20,000–30,000 Wa soldiers, led by Bao Youxiang. The UWSA was formed after the collapse of the armed wing of the Communist Party of Burma (CPB) in 1989.
