Chairman Cheng

Communist Party of China chairman Cheng was the president of China from at least 2066 until the Great War in 2077. Under his rule, in 2066 China invaded the US state of Alaska.

Appearances
Chairman Cheng does not appear in any of the games and is mentioned only in Fallout 3.

Behind the scenes
Irving Cheng is possibly a nod to Ashley Cheng, production director at Bethesda Softworks.

Inconsistencies
In Fallout 2, the Sierra Depot GNN Transcript holodisk mentions a president of China named Xin, but this holodisk includes many inconsistencies with the established timeline, and was stated to be non-canon by Chris Avellone in the Fallout Bible. The explanation given by Avellone for the inconsistencies was that the transcript was tampered with by bored Sierra Army Depot soldiers.
