Cheng (Chairman)

Chairman Cheng was the leader of the Communist Party of China and the head of state of the People's Republic. Under his rule, China clashed with the United States in the Sino-American War, invading Alaska in 2066. Despite initial successes, the Chinese military was forced into a stalemate by the American defenders and eventually beaten back all the way to the Chinese mainland. Despite that, even as late as 2077, Chinese troops continued to fight in Chairman Cheng's name, indicating he held onto power despite the looming defeat.

The senile Irving Cheng at Tenpenny Tower claims to be descended from Chairman Cheng in 2277, though it is unknown whether this is his imagination or something more substantial.

Behind the scenes

 * The GNN News Transcript references a President Xin as the head of state, however, Fallout 3 has explicitly retconned this. The translation of the Chinese term for the President of the People's Republic of China is 中华人民共和国主席: Chairman of the People's Republic of China (technically, Chairperson).
 * One of the available mustaches is called Chairman Cheng and resembles the iconic facial hair of the dreaded Fu Manchu.
 * His name is a reference to Ashley Cheng, production director at Bethesda Softworks.

Appearances
Chairman Cheng is mentioned in Fallout 3, the add-on Operation: Anchorage, and Fallout 4.
