Trump's Taiwan policy sparks controversy: Former officials warn about the risks of strategic ambiguity, and tariff policies damage the trust of Indo-Pacific allies.

In May 2025, during his second term, former President of the United States, Donald Trump, re-adopted the "strategic ambiguity" stance on Taiwan policy, which drew international attention. Trump did not make an explicit commitment to defend Taiwan, as some former officials believe this strategy helps maintain regional stability. At the same time, the Trump administration imposed high tariffs on Taiwan and its Indo-Pacific allies, which increased doubts among regional countries about U.S. commitments, impacting both economic and diplomatic relations. This article examines the policy background and the warnings issued by former officials, highlighting the tense relationship between U.S. policy towards Taiwan and its Indo-Pacific strategy.

This article examines the policy background and the warnings issued by former officials, highlighting the tense relationship between U.S. policy towards Taiwan and its Indo-Pacific strategy.
Trump Reverts to "Strategic Ambiguity," Taiwan Faces Uncertainty
On May 12, 2025, during a White House press conference discussing US-China trade negotiations, President Trump mentioned the possibility of "reunification and peace." Although he did not explicitly mention Taiwan, it immediately raised high alert in Taipei. The office of Taiwan President Lai Ching-te quickly issued a statement emphasizing that they had not received any information about negotiations involving Taiwan and demanded clarification from the US.
Trump's remarks were interpreted by observers as possibly hinting at some form of deal between the US and China on the Taiwan issue, echoing his past praise for Chinese President Xi Jinping. Thomas J. Shattuck, a senior project manager at the University of Pennsylvania's Perry World House, noted that Trump's return to a "strategic ambiguity" stance contrasts sharply with former President Biden's repeated public commitments to defend Taiwan with "strategic clarity."
Former Officials Warn: Strategic Clarity May Backfire
Regarding the debate over strategic ambiguity and clarity, former US Assistant Secretary of Defense for Indo-Pacific Affairs Ely Ratner publicly stated that adopting strategic clarity on Taiwan provides "almost no benefits and only drawbacks." He pointed out that China has long anticipated possible US intervention in a Taiwan Strait conflict and has been preparing militarily. If the US clearly states it will defend Taiwan, it may instead provoke Beijing's actions and cause political turmoil within the US.
Ratner emphasized that strategic clarity not only fails to deter China but may also make Taiwan the focal point of international conflict. He believes that maintaining a policy of ambiguity, though imperfect, remains the best option to balance deterrence and stability.
Tariff Policy Impacts Ally Trust, Indo-Pacific Strategy Faces Challenges
In addition to the controversy over Taiwan policy, the Trump administration's recent implementation of "reciprocal tariffs" has drawn widespread attention in the Indo-Pacific region. On April 2, 2025, the US announced a minimum 10% across-the-board tariff on most trade partners, including Taiwan, Japan, South Korea, Australia, and ASEAN countries, with some countries like Taiwan facing tariffs as high as 32%. Although the US announced on April 9 a 90-day suspension of further tariff increases for non-China countries, the uncertainty has already impacted regional economic and diplomatic relations.
Former US Deputy Assistant Secretary of Defense Richard Lawless warned that if the US continues to prioritize economic interests over security commitments, it may drive away newly established alliances in the Indo-Pacific region. He noted that these countries might question the US's strategic sincerity, thereby weakening regional cooperation and security frameworks.
Taiwan's Difficult Situation: Dual Pressure from Economy and Security
Under the dual pressure of the Trump administration's strategic ambiguity and tariff policy, Taiwan faces unprecedented challenges. According to a report by Taiwan Insight, Taiwan's exports to the US have been significantly impacted by the new tariff policy, especially the semiconductor industry facing potential tariff increases. Although Taiwan's economic performance was strong in the first quarter of 2025, future growth forecasts are overshadowed by US policy uncertainty.
Additionally, Taiwan's inability to join the Regional Comprehensive Economic Partnership (RCEP) and the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) places it at a disadvantage in regional economic integration. This leaves Taiwan lacking sufficient alternative markets and bargaining chips when facing US tariff pressure.
Indo-Pacific Allies in a Wait-and-See Position, US Credibility Tested
The Trump administration's trade policy has also left other Indo-Pacific allies in a wait-and-see position. According to a PECC report, ASEAN economic ministers decided at their February 2025 meeting not to take retaliatory measures against US tariffs, instead emphasizing resolving disputes through dialogue. However, regional countries are increasingly doubting whether the US remains a reliable partner.
CSIS analysis pointed out that if the US continues to adopt high-pressure economic measures against allies, it will accelerate regional countries' pursuit of other economic cooperation mechanisms, further weakening US influence in the Indo-Pacific. This policy uncertainty and unilateralism have become a significant risk to the US Indo-Pacific strategy.
