U.S. President Jimmy Carter announces that the United States will recognize the People's Republic of China and sever diplomatic relations with the Republic of China (Taiwan).

James Earl Carter Jr. was an American politician and humanitarian who served as the 39th president of the United States from 1977 to 1981. A member of the Democratic Party, Carter served from 1971 to 1975 as the 76th governor of Georgia and from 1963 to 1967 in the Georgia State Senate. He was the longest-lived president in U.S. history and the first to reach the age of 100.

The relationship between the People's Republic of China (PRC) and the United States of America (USA) is the most important bilateral relationship in the world. It has been complex and at times tense since the establishment of the PRC and the retreat of the government of the Republic of China to Taiwan in 1949. Since the normalization of relations in the 1970s, the US–China relationship has been marked by persistent disputes including China's economic policies, the political status of Taiwan and territorial disputes in the South China Sea. Despite these tensions, the two nations have significant economic ties and are deeply interconnected, while also engaging in strategic competition on the global stage. As of 2025, China and the United States are the world's second-largest and largest economies by nominal GDP, as well as the largest and second-largest economies by GDP (PPP) respectively. Collectively, they account for 44.2% of the global nominal GDP, and 34.7% of global PPP-adjusted GDP.

After the United States established diplomatic relations with the People's Republic of China (PRC) in 1979 and recognized Beijing as the only legal government of China, Taiwan–United States relations became unofficial and informal following terms of the Taiwan Relations Act (TRA), which allows the United States to have relations with the Taiwanese people and their government, whose name is not specified. U.S.–Taiwan relations were further informally grounded in the Six Assurances in response to the third communiqué on the establishment of US–PRC relations. The Taiwan Travel Act, passed by the U.S. Congress on March 16, 2018, allows high-level U.S. officials to visit Taiwan and vice versa. Both sides have since signed a consular agreement formalizing their existent consular relations on September 13, 2019. The US government removed self-imposed restrictions on executive branch contacts with Taiwan on January 9, 2021.
