In 1971, the government of the Republic of China (ROC) exited the United Nations just before the organization acknowledged the People's Republic of China (PRC) as the lawful representative of China's seat at the UN. While a dual representation proposal was on the table, Chiang Kai-shek, the leader of the ROC, insisted on keeping a seat on the UN Security Council, a condition the PRC would not agree to. Chiang articulated his stance in a notable speech, declaring "the sky is not big enough for two suns." Consequently, the UN General Assembly passed Resolution 2758 in October 1971, ousting "the representatives of Chiang Kai-shek" and thus the ROC, and designating the PRC as the official "China" within the UN. In 1979, the United States also shifted its diplomatic recognition from Taipei to Beijing.
