US Secretary of State Rex Tillerson, in response to a question from US Senator Ben Cardin, said in a written statement on Feb. 1 that the Three Joint Communiques, the Taiwan Relations Act (TRA) and the “six assurances” provide the foundation for US policy toward Taiwan and China.
As required by the TRA, the US will continue to provide Taiwan with arms of a defensive character and help maintain its capacity to resist any resort to military force or other forms of coercion that would jeopardize the security or the social or economic systems of Taiwan, he said.
“The US commitment to Taiwan is both a legal commitment and a moral imperative,” Tillerson said.
This is the first time the US Department of State has clearly described its legal commitment to Taiwan based on the TRA.
However, if the US intervenes in a cross-strait conflict and helps Taiwan resist Chinese military forces as required by the TRA, would that contravene the “one China” policy established in the three communiques? This is a question that needs further clarification.
First, the TRA does not deny that there is “one China.” Since the US, through the Three Communiques, “recognizes the Government of the People’s Republic of China as the sole legal government of China,” it will not use the TRA to extend dual recognition to the Republic of China (ROC).
A US court ruling in a lawsuit between the State Bank of Pakistan and the International Commercial Bank of China (now Mega International Commercial Bank) also established that the TRA does not recognize the ROC.
How can the US recognize that there is “one China” and still intervene in a cross-strait conflict without contravening the principle of non-intervention and international law such as UN General Assembly Resolutions 2131 and 2625 — the Declaration on the Inadmissibility of Intervention in the Domestic Affairs of States and the Protection of Their Independence and Sovereignty, and the Declaration on Principles of International Law concerning Friendly Relations and Co-operation among States?
This means that for the US, recognizing “one China” does not mean that Taiwan is a part of China, but rather remains a temporary entity that enjoys special international rights. It can therefore rely on the TRA to help Taiwanese maintain the assets, natural resources and basic human rights that they have had since Taiwan was occupied by the ROC.
As history has taught us, an entity with special rights such as Taiwan must be protected by international law, or it would easily be destroyed by external powers.
However, Taiwan has never been placed under UN trusteeship, nor has the UN Security Council issued any resolutions protecting Taiwanese.
As leader of the allied nations since 1945, the US had to unilaterally create the TRA to have a legal basis for acting as the world’s police and protecting Taiwan’s special status.
This can be verified by looking at the similarities between the defensive actions the TRA demands from the US, and the collective self-defense rights stipulated in the Sino-US Mutual Defense Treaty that expired on Dec. 31, 1979.
An example of this was when the US sent an aircraft carrier group to the vicinity of the Taiwan Strait during the 1996 Taiwan Strait crisis.
The TRA is against any military force to change Taiwan’s status for very specific reasons, one of them being “the human rights of all the approximately 18 million inhabitants of Taiwan.”
According to the TRA, “the preservation and enhancement of the human rights of all the people on Taiwan” are among the US’ objectives.
The human rights that the TRA protects include the right of Taiwanese to self-determination, and the right to build a new, independent nation based on Articles 2 and 5 of the UN Charter and other jus cogens — peremptory norms — of international law.

In the US’ National Security Strategy (NSS) report released last month, US President Donald Trump offered his interpretation of the Monroe Doctrine. The “Trump Corollary,” presented on page 15, is a distinctly aggressive rebranding of the more than 200-year-old foreign policy position. Beyond reasserting the sovereignty of the western hemisphere against foreign intervention, the document centers on energy and strategic assets, and attempts to redraw the map of the geopolitical landscape more broadly. It is clear that Trump no longer sees the western hemisphere as a peaceful backyard, but rather as the frontier of a new Cold War. In particular,
When it became clear that the world was entering a new era with a radical change in the US’ global stance in US President Donald Trump’s second term, many in Taiwan were concerned about what this meant for the nation’s defense against China. Instability and disruption are dangerous. Chaos introduces unknowns. There was a sense that the Chinese Nationalist Party (KMT) might have a point with its tendency not to trust the US. The world order is certainly changing, but concerns about the implications for Taiwan of this disruption left many blind to how the same forces might also weaken
As the Chinese People’s Liberation Army (PLA) races toward its 2027 modernization goals, most analysts fixate on ship counts, missile ranges and artificial intelligence. Those metrics matter — but they obscure a deeper vulnerability. The true future of the PLA, and by extension Taiwan’s security, might hinge less on hardware than on whether the Chinese Communist Party (CCP) can preserve ideological loyalty inside its own armed forces. Iran’s 1979 revolution demonstrated how even a technologically advanced military can collapse when the social environment surrounding it shifts. That lesson has renewed relevance as fresh unrest shakes Iran today — and it should
As the new year dawns, Taiwan faces a range of external uncertainties that could impact the safety and prosperity of its people and reverberate in its politics. Here are a few key questions that could spill over into Taiwan in the year ahead. WILL THE AI BUBBLE POP? The global AI boom supported Taiwan’s significant economic expansion in 2025. Taiwan’s economy grew over 7 percent and set records for exports, imports, and trade surplus. There is a brewing debate among investors about whether the AI boom will carry forward into 2026. Skeptics warn that AI-led global equity markets are overvalued and overleveraged
