United Nations and was recognized by many U.N. nations.

The claims eventually prompted the U.N. to change its diplomatic recognition from the RoC in Taiwan to the People's Republic of China (PRC) on mainland China. As a result, the U.N. expelled Taiwan in 1971 and recognized the CCP/PRC as the official Chinese government.
