Ever since the US ended diplomatic relations with the Republic of China (ROC) and recognized the People’s Republic of China (PRC) in 1979, a move followed by the passage of the US’ Taiwan Relations Act (TRA) in April that year, Washington’s policy on Taiwan has consistently been that its future cannot be determined through the use of force by China.
The diplomatic relationship with Beijing, the TRA reads, “rests upon the expectation that the future of Taiwan will be determined by peaceful means [and that] any effort to determine the future of Taiwan by other than peaceful means, including by boycotts or embargoes” would be “of grave concern” to the US.
