U.S.-Taiwan relations are characterized by a strong unofficial partnership, primarily driven by shared democratic values and economic interests. The United States supports Taiwan's self-governance and provides military assistance under the Taiwan Relations Act, which allows for defensive arms sales to Taiwan. Economically, the U.S. and Taiwan engage in significant trade, with Taiwan being a key player in the global technology supply chain. The two sides collaborate on various issues, including trade agreements and regional security, while the U.S. maintains a policy of strategic ambiguity regarding Taiwan's status in relation to China.
