TAIPEI, Taiwan — A newly enacted United States law requiring a review of American policy toward Taiwan underscores the island’s value as a democratic ally for Washington and comes amid fierce criticism from China. The bill, which gained overwhelming bipartisan support in Congress and was signed into law Dec. 2, 2025, has been hailed as a milestone and denounced as an infringement on Chinese sovereignty.
What the Taiwan Assurance Implementation Act does
The Taiwan Assurance Implementation Act modifies the 2020 Taiwan Assurance Act to include a provision requiring that as long as the United States maintains internal guidance for its approach to working with Taiwan, the secretary of state must review such guidance no fewer than once every five years, reissue it across the executive branch and submit an updated report on it to appropriate Congressional committees within 90 days. The legislative text of H.R. 1512 indicates that such a report shall include an explanation of how the updated guidelines are consistent with existing policy goals, as well as the removal of any self-imposed restrictions lifted from documents such as the long-standing “Guidelines on Relations with Taiwan.”
The measure moved through the House and Senate earlier this year in companion versions sponsored by lawmakers such as Sens. John Cornyn, Michael Bennet, and Chris Coons, who said it was a response to escalating Chinese coercion and an effort to ensure support for Taiwan transcended any single administration. For their part, supporters say that because the new legislation would make regular reviews the law, it should prevent future administrations from quietly resurrecting older, more restrictive guidance without alerting Congress or U.S. partners in Asia.
Taipei applauds, Beijing protests.
In Taipei, officials there cast the Taiwan Assurance Implementation Act as a bulwark against backsliding. Karen Kuo, spokesperson for the Presidential Office In a statement, said that the law confirms the importance of U.S. engagement with Taiwan and reflects shared democratic values, and pledged to use the new framework to further cooperation in security, trade and global health. “His remarks were uploaded on the Presidential Office website, where Kuo thanked Trump and Congress and promised to keep cooperating with ‘like-minded partners’ to maintain regional stability.
In Beijing, the Foreign Ministry accused Washington of “seriously violating” the principle and of interfering in China’s internal affairs, saying it would respond with unspecified countermeasures. A Reuters dispatch said China called on the United States to put a stop to all official interaction with Taiwan and halt what it referred to as “wrong signals” sent to pro-independence forces in Taiwan.
One piece in a broader arc of U.S.-Taiwan legislation
The new law is part of a broader timeline of American efforts to relax long-standing restrictions on contacts with Taipei. In 2018, Congress overwhelmingly approved the Taiwan Travel Act, which allows for high-level visits between U.S. and Taiwanese officials, and then-President Donald Trump signed it into law, building on the 1979 Taiwan Relations Act, which provides an extensive framework for unofficial ties. An article in the Diplomat at the time contended that, because the travel law effectively contravened decades of self-imposed restraints by advocating greater exchange among people, it was a direct response to such calls for openness.
Those restrictions were loosened again in January 2021, when then-Secretary of State Mike Pompeo declared all internal rules on contacts with Taiwanese officials “null and void,” a move welcomed by Taiwan and decried by China. As Reuters noted at the time, leaving it to the next administration to determine some form of guidance on U.S.–Taiwan relations effectively ensured that Trump had cemented his disruption of decades-old diplomatic principles.
And by enacting the Taiwan Assurance Implementation Act into law, Congress is now charting a middle course: maintaining formal guidance while requiring it to be periodically refreshed and making transparent which self-imposed capital suffocation is removed. Supporters say this will institutionalise a more open U.S.-Taiwan relationship while still leaving room for manoeuvre as regional dynamics change and China ramps up military and diplomatic pressure around the island.
In the next few months, the State Department under Secretary of State Marco Rubio is to conduct its first review under the Taiwan Assurance Implementation Act and be required to submit an updated report to Congress, a process that will reveal whether Washington plans in effect to megalize contacts that already have become routine, from senior congressional delegations to regular transit stops by Taiwanese presidents through U.S. cities. Trump will also likely face more questions about the Taiwan Assurance Act during a planned visit to China in April for discussions with President Xi Jinping, highlighting how the island has become a central sticking point amid tense U.S.–China relations.
