Data notes
The final version of the law, as each chamber passed it. A chamber that passed it by voice vote or unanimous consent has no count. “Method not stated” means the record does not say how the chamber voted. Where the record has a member-by-member vote, the “Who voted for it” section shows who voted yea.
Summary
The Congressional Research Service’s plain-language summary of what the law does.
This bill modifies an existing requirement for the Department of State to review and report on its guidance to federal agencies on the U.S.-Taiwan relationship. (The U.S.-Taiwan relationship has been unofficial since 1979, when the United States established diplomatic relations with China and broke them with Taiwan.)
Current law requires the State Department to conduct a one-time review of its guidance governing relations with Taiwan and report to Congress on this review. Under this bill, the State Department must review that guidance and report to Congress every two years while the guidance is in effect.
The reports to Congress must (1) describe how the guidance takes into account certain considerations, such as the sense of Congress that Taiwan is governed by a representative government peacefully constituted through free and fair elections; and (2) identify opportunities and plans to lift self-imposed restrictions on relations with Taiwan.
