United States. Embassy (Taiwan) 1949 - 1979
From December 19, 1949, until February 28, 1979, the United States Embassy in China was located in Taipei, Taiwan, as the US government continued to recognize the Republic of China (ROC) as the legitimate government of China, even after the ROC government had fled the mainland and and controlled only the island of Taiwan and other offshore islands.
Following the establishment of diplomatic relations between the United States and the People's Republic of China (PRC) in January 1979, the US government ceased its recognition of the Republic of China. The US Embassy in Taiwan was closed. On March 1, 1979, the United States opened an embassy in Beijing, China.
Although still officially known as the US Embassy in China during its operation in Taiwan, the Wilson Center Digital Archive refers to it simply as "United States. Embassy (Taiwan)" to avoid confusion with US representation in the PRC. "United States. Embassy (China)" instead refers to the US Embassy in the People's Republic of China.
After the closure of the American embassy in Taipei, the American Institute in Taiwan (AIT) opened in 1979. AIT is a wholly owned subsidiary of the federal government of the United States in Taiwan with Congressional oversight.
