The Grand Unification of China began when the Pacific Empire started to lose against North Korea in the Invasion of South Korea. The People's Republic of China then decided that it is time to get back their rightful territories and provinces. Namely, these Imperial colonies that China wanted were Hong Kong, Macau, Hainan, Guangxi, Guangdong, Fujian, Zhejiang, Yunnan, Shanghai, and Taiwan. China also used the Rebellion of Vietnam as a distraction for the Imperial Military.
