People's Republic of China (1983: Doomsday)

The New People's Republic of China in Guanxi (Simplified Chinese:新兴中华人民共和国于广西), or the Guangxi Zhuang Autonomous Region, is one of the few regions in China that didn't face nuclear destruction.

Background
The whole government of China, including President Li Xiannian, was killed in Bejing. The secratary of the CPC, Qiao Xiaoguang, took over the province by offically declaring independence from the no longer existing People's Republic of China.
