The United States approach to Taiwan has remained consistent across decades and administrations. The United States has a longstanding one China policy, which is guided by the Taiwan Relations Act, the three U.S.-China Joint Communiques, and the Six Assurances. We oppose any unilateral changes to the status quo from either side; we do not support Taiwan independence; and we expect cross-Strait differences to be resolved by peaceful means.
