The People's Republic of China (PRC) regards itself as the "successor state" of the Republic of China (ROC), which the PRC claims no longer legitimately exists, following establishment of the PRC in mainland China. The PRC asserts itself to be the sole legitimate government of China, and claims Taiwan as its 23rd province, even though the PRC itself has never had control of Taiwan or other ROC-held territories. The ROC disputes this position, maintaining that it still legitimately exists and that the PRC has not succeeded it to sovereignty.
