The "Six Assurances to Taiwan Act" aims to formally codify the United States' long-standing Six Assurances to Taiwan, which have guided U.S.-Taiwan relations since 1982. These assurances clarify that the U.S. has not agreed to set a date for ending arms sales to Taiwan, consult with the People's Republic of China (PRC) on such sales, or play a mediation role between Taiwan and the PRC. Furthermore, they affirm that the U.S. has not sought to revise the Taiwan Relations Act, altered its position on Taiwan's sovereignty, or exerted pressure on Taiwan to negotiate with the PRC.

A central provision of the bill establishes a robust congressional review process for any presidential actions that could impact these assurances. The President would be required to notify Congress before taking specific actions, including pausing or terminating defensive arms sales to Taiwan, negotiating with the PRC about such sales, mediating on sovereignty issues, changing the U.S. position on Taiwan's sovereignty, or pressuring Taiwan into negotiations with the PRC.

Upon notification, Congress would have a 30-day (or 60-day during summer) period to review the proposed action. During this time, the President would be prohibited from taking the action or expending funds for it unless Congress enacts a joint resolution of approval. Conversely, if Congress passes a joint resolution of disapproval, the President would face further restrictions on implementing the action, including during potential veto and override processes.

This legislative framework underscores Congress's view that maintaining peace and stability across the Taiwan Strait is vital for U.S. political, security, and economic interests. It emphasizes that any unilateral change to the status quo or a negotiated settlement without the consent of both sides is unacceptable, and that the Six Assurances are a necessary component of U.S. policy toward Taiwan.
