This bill aims to enhance transparency and oversight regarding the Department of State's guidelines on relations with Taiwan by amending Section 315 of the existing Taiwan Assurance Act of 2020. It expands the scope of documents considered as guidance to include any successor or related documents that govern U.S. relations with Taiwan. The legislation mandates that the Secretary of State conduct a comprehensive review of all such guidance at least once every five years, reissuing it to executive branch departments and agencies. Within 90 days of completing each review, an updated report must be submitted to the Senate Committee on Foreign Relations and the House Committee on Foreign Affairs. These reports are required to include existing mandated information and a description of how the updated guidance fulfills its established goals and objectives.
