Trump Says He Made No Commitment on Taiwan During Xi Summit, Describes Talks as Successful

Aboard Air Force One on May 15, 2026, President Donald Trump offered a single sentence that sent analysts, allied governments, and Taiwanese officials scrambling for interpretation: "On Taiwan he feels very strongly. I made no commitment either way" [1]. Asked directly whether the United States would defend Taiwan if China attacked, Trump said he told Xi Jinping, "I don't talk about that" [2].

The remark capped a two-day state visit to Beijing — the first by a sitting U.S. president since Trump's own 2017 trip — that was heavy on ceremony and thin on concrete results. Secretary of State Marco Rubio, standing in Beijing, insisted that "U.S. policy on the issue of Taiwan is unchanged" [3]. But the gap between Rubio's reassurance and Trump's studied noncommitment has become the central puzzle of the summit's aftermath.

What the Summit Produced — and What It Did Not

The Beijing meeting was built on the foundation of the October 30, 2025, Busan summit, where the two leaders struck a partial trade truce: Trump cut fentanyl-related tariffs on China from 20% to 10%, bringing the effective overall tariff rate from 57% to 47%; Beijing paused rare-earth export controls for one year and resumed agricultural purchases [4][5]. That truce remains intact. No new tariff reductions were announced in Beijing.

The effective U.S. tariff rate on Chinese imports, which peaked at 145% in April 2025 before a rapid de-escalation, has held steady at 47% since the Busan deal. The Beijing summit did not alter these rates.

On other agenda items, progress was uneven. Trump and Xi discussed the Iran conflict, with both sides agreeing the Strait of Hormuz must remain open to shipping — a point of alignment driven by China's dependence on Middle Eastern oil and Japan's dependence on the same shipping lanes [6]. They exchanged views on the Ukraine crisis and the Korean Peninsula but announced no joint initiatives. Trump raised the case of imprisoned Hong Kong publisher Jimmy Lai before the visit but has not publicly confirmed any Chinese concessions [7]. TikTok's status in the United States, subject to a divestiture order that has been repeatedly extended, did not feature prominently in public readouts.

The White House described the talks as "very successful" [8]. Trump told Fox News the summit was "amazing" and that a comprehensive trade deal could come "pretty soon" — a phrase he also used after the Busan meeting seven months earlier [5].

The Taiwan Divergence: Two Summits, Two Stories

The starkest outcome of the Beijing summit is the gap between the American and Chinese accounts of what happened regarding Taiwan.

The White House readout made no mention of Taiwan [3]. China's readout placed it front and center. According to Beijing's official statement, Xi told Trump that Taiwan "is the most important issue in China-U.S. relations. If it is handled properly, the bilateral relationship will enjoy overall stability. Otherwise the two countries will have clashes and even conflicts, putting the entire relationship in great jeopardy" [9].

Chinese Foreign Minister Wang Yi went further, telling state media: "We sensed during the meeting that the U.S. side understands China's position and attaches importance to China's concerns, and, like the international community, does not support or accept Taiwan moving toward independence" [10]. This characterization — suggesting Trump signaled sympathy for Beijing's position — stands in direct tension with Rubio's claim that U.S. policy is "unchanged."

The pattern of divergent readouts is not new. After the November 2023 Biden-Xi meeting in San Francisco, Chinese state media similarly emphasized areas of convergence that U.S. officials downplayed. But the current gap is wider, because Trump's own words — "no commitment either way" — are more amenable to Beijing's interpretation than any recent presidential statement on Taiwan.

The $14 Billion Arms Package in Limbo

Taiwan's most immediate concern is not rhetorical ambiguity but hardware. A $14 billion weapons package — the largest ever proposed for Taiwan — has been stalled in the State Department for months [11]. A bipartisan group of senators, including members of the Foreign Relations Committee, pressed Trump to approve it before the Beijing trip, but the package was not finalized [12].

The arms sale backlog tells a broader story. According to the Taiwan Security Monitor at George Mason University's Schar School, the total value of approved but undelivered arms sales to Taiwan stood at $32 billion as of January 2026 — up from $20.5 billion in 2023 and just $8.2 billion in 2019 [13].

Some deliveries are proceeding: 80 of 108 M1A2T Abrams tanks have arrived in Taiwan, with 28 more in transit, and ALTIUS loitering munitions have been delivered [13]. But newer systems remain in bureaucratic limbo. Taiwan's legislature authorized the signing of $9 billion in stalled deals earlier in 2026, a step meant to clear a procedural obstacle on Taipei's end [14].

China sanctioned 20 U.S. defense companies and 10 executives in December 2025 over the pending sales — a move that, while largely symbolic (most of these companies have no significant China operations), signaled Beijing's increasing willingness to use economic tools against the defense relationship [15].

Trump, asked about the $14 billion package, said he would "make a determination over the next fairly short period" after speaking to "the person that's running Taiwan" [1].

Taiwan's Response: Measured Words, Deep Anxiety

Taipei's official response was carefully calibrated. A spokesperson for Taiwan's premier said the government "views all actions that contribute to regional stability and the management of potential risks from authoritarian expansion positively," adding that the U.S. "has repeatedly reiterated its firm and clear position of support for Taiwan" [16].

Before the summit, Taiwan's National Security Bureau Director-General Tsai Ming-yen told reporters that the U.S. had "repeatedly reiterated, through both public and private channels, that its policy toward Taiwan remains unchanged" [16]. Taiwanese officials have emphasized back-channel stability, pointing to continuous contact with U.S. military commanders at INDOPACOM — a relationship that has operated largely independent of the White House's diplomatic messaging [7].

Taiwan's TAIEX stock index rose 0.9% during the summit, buoyed by broader market optimism about U.S.-China trade stability [17]. The index had crossed 40,000 points for the first time on May 4, before the summit began [18]. The modest rally suggests investors are, for now, pricing in continuity rather than disruption — though market sentiment could shift quickly if the arms package is formally delayed or canceled.

The Strategic Ambiguity Debate

Trump's "no commitment either way" formulation is, in one reading, simply the latest iteration of the United States' long-standing policy of strategic ambiguity — the deliberate refusal to say whether America would or would not defend Taiwan in the event of a Chinese attack.

Scholars who favor maintaining ambiguity argue it creates dual deterrence. Beijing is deterred from attacking because it cannot be certain the U.S. would stay out; Taipei is deterred from provoking Beijing because it cannot be certain the U.S. would intervene [19]. The Quincy Institute's Michael Swaine has argued that a formal defense commitment would risk "moral hazard" — emboldening Taiwan to take provocative steps toward formal independence while locking the U.S. into a potential great-power war [20].

On the other side, scholars at Brookings and the U.S. Naval Institute have argued that ambiguity has become dangerous as China's military capabilities have grown. Richard Haass and David Sacks wrote in a widely cited 2020 Foreign Affairs piece that the policy "no longer works" because China's leaders may now calculate that they could present the U.S. with a fait accompli before Washington could decide to respond [21]. The Heritage Foundation has argued that clarity — an explicit commitment to defend Taiwan — would strengthen deterrence by removing any doubt in Beijing's calculations [22].

Trump's formulation differs from both camps. Traditional strategic ambiguity involves not answering the question. Trump answered it — "no commitment either way" — which is arguably a third position: explicit noncommitment. Whether this strengthens or weakens deterrence depends on Beijing's reading. If China interprets it as a signal that Trump might stay out, it could embolden military planners. If China interprets it as Trump keeping his options open — including devastating economic retaliation or military intervention — it preserves some deterrent effect.

Legal Guardrails: What Congress Can and Cannot Do

Regardless of what Trump said or did not say privately, the president does not have unchecked authority over Taiwan policy. The Taiwan Relations Act (TRA) of 1979 establishes several legal constraints [23].

The TRA requires the United States to "provide Taiwan with arms of a defensive character" and to "maintain the capacity of the United States to resist any resort to force or other forms of coercion that would jeopardize the security, or the social or economic system, of the people on Taiwan" [23]. This language does not mandate a military defense of Taiwan, but it does create a statutory obligation to supply defensive weapons — meaning a president who froze arms sales entirely could face legal challenges and congressional pushback.

The TRA also requires the president to "inform the Congress promptly of threats to the security or the social or economic system of the people on Taiwan" [23]. Congress and the president jointly determine the "appropriate action" in response to such threats.

Recent congressional action has reinforced these obligations. The Taiwan Policy Act, versions of which have been introduced in multiple sessions, sought to designate Taiwan as a "major non-NATO ally" and mandate specific weapons systems. While the act has not passed in its strongest form, its provisions signal congressional intent to constrain executive discretion. The bipartisan pressure on Trump to approve the $14 billion arms package before the Beijing trip reflects this dynamic [12].

Regional Allies Watch With Concern

U.S. treaty allies in the Indo-Pacific responded to the summit with a mix of public restraint and private unease. Japan, the most directly affected ally given its proximity to Taiwan and its dependence on Middle Eastern oil transiting the Strait of Hormuz, dispatched Prime Minister Takaichi and senior cabinet members on a pre-summit diplomatic offensive to Vietnam and Australia, promoting the Free and Open Indo-Pacific strategy as an alternative framework to a U.S.-China bilateral deal that might sideline Japanese interests [24].

The Philippines, which has been engaged in an escalating confrontation with China over South China Sea territorial claims, signed a reciprocal access agreement with Japan in 2024 and has expanded military exercises with Australia — hedging moves that predate the summit but reflect a broader pattern of Indo-Pacific states seeking defense relationships beyond Washington [24].

South Korea, which conducts nearly 40% of its total goods trade with the U.S. and China combined, has adopted a cautious wait-and-see approach, seeking to extract short-term gains on trade and supply chain issues from any reduction in U.S.-China tension [24].

The Lowy Institute's assessment captured the regional mood: governments across Southeast Asia hope for a "Goldilocks" U.S.-China relationship — stable enough to prevent conflict but not so cooperative that decisions affecting their security are made exclusively in Washington and Beijing [24].

What Comes Next

The summit's most consequential loose end is the $14 billion arms package. Trump's promise to "make a determination" soon puts a clock on the issue. If he approves the package, it would represent the largest single weapons sale to Taiwan in history and undercut Beijing's claim that Trump "understands" China's position. If he delays or scales it back, it would validate the concerns of those who see his noncommitment as a signal of weakening resolve.

The divergent readouts present a second challenge. Wang Yi's assertion that Trump "understands" Beijing's concerns on Taiwan will be taken at face value in many capitals unless the White House explicitly pushes back. Rubio's "unchanged" formulation offers some rebuttal, but it lacks the force of a presidential statement.

For Taiwan, the immediate calculus is clear: accelerate self-defense investments, maintain back-channel military ties with INDOPACOM, and avoid giving either Washington or Beijing a reason to treat the island as a liability. For Beijing, the summit reinforced a negotiating position in which Taiwan is the central lever in the bilateral relationship — a framing Xi made explicit and Trump did not publicly reject.

The Taiwan Strait has been managed for 47 years under the framework established by the TRA and the three U.S.-China joint communiqués. Whether Trump's "no commitment either way" represents a continuation of that framework, a departure from it, or something else entirely may depend less on what was said in Beijing than on what happens in the weeks that follow.
