The Taiwan Relations Act is a U.S. law enacted in 1979 that governs the relationship between the United States and Taiwan. It was established after the U.S. shifted diplomatic recognition from Taiwan to the People's Republic of China. The Act allows for unofficial relations and provides a framework for arms sales to Taiwan, ensuring that the U.S. can support Taiwan's self-defense. The Act emphasizes the importance of peace and stability in the Taiwan Strait and encourages dialogue between Taiwan and China. It reflects the U.S. commitment to Taiwan's security while maintaining a policy of strategic ambiguity regarding military intervention in the event of a conflict.
