Taiwan, officially the Republic of China, is a state in East Asia neighboring Japan and the People’s Republic of China. When the People’s Republic of China established control over mainland China following the Chinese Civil War, the ROC relocated its government to Taiwan and has remained there ever since. The PRC claims Taiwan as their province and denies their existence as a sovereign state. Due to the PRC’s refusal to maintain diplomatic relations with countries that recognize Taiwan, only 22 nations formally recognize the nation; however, the US is one of the ROC’s main allies and has provided arms and training since 1979.
