The American Institute in Taiwan is the de facto Embassy of the United States of America in Taiwan. The AIT institution is a wholly owned subsidiary of the federal government of the United States in Taiwan with Congressional oversight. The AIT was officially created as a U.S. government-sponsored non-profit, private corporation established under the auspices of the U.S. government to serve its interests in Taiwan. Primarily staffed by employees of the United States Department of State and local workers, the AIT provides consular services normally offered by normal United States diplomatic missions, with the Great Seal of the State Department hung at AIT's main office in Taipei. The establishment of diplomatic relations with the People's Republic of China (PRC) in 1979 required acknowledgment of the "one-China policy" and subsequent termination of diplomatic relations with the Republic of China (Taiwan). The AIT now serves to assist and protect U.S. interests in Taiwan in a quasi-official manner, and also processes US visas and provides consular services to U.S. expatriates. Following the swift passage of the 2018 Taiwan Travel Act by the United States, it now serves as a high-level representative bureau on behalf of United States in Taiwan. It receives full protection from the United States Marine Corps as do all US Embassies.
The Taipei Economic and Cultural Representative Office (TECRO), also known as Taipei Economic and Cultural Office (TECO), Taipei Representative Office (TRO) or Taipei Mission, is an alternative diplomatic institution serving as a de facto embassy or a consulate of the Republic of China which exercises the foreign affairs and citizen services in specific countries having diplomatic relations with the People's Republic of China. As the PRC denies the legitimacy of the ROC as a sovereign state and claims the ROC-controlled territories as an integral part of its China. An exclusive mandate namely One-China policy, mandates any country that wishes to establish a diplomatic relationship with the PRC must first sever any formal relationship with the ROC. According to The Fletcher Forum of World Affairs, "non-recognition of the Taiwanese government is a prerequisite for conducting formal diplomatic relations with the PRC—in effect forcing other governments to choose between Beijing and Taipei." As a result, these countries only allow the ROC to establish representative offices instead of an "official" embassy or consulate for the purpose of conducting practical bilateral relations without granting full diplomatic recognition.
