Xi-Trump Summit Tests U.S. Reset as Taiwan Concerns Grow in Tokyo and Taipei

China’s top diplomat and the U.S. secretary of state have moved into final-stage summit preparations, placing the expected September 24 meeting between Xi Jinping and Donald Trump at the center of a broader test: whether Washington can seek a reset with Beijing without alarming the partners most exposed to Chinese pressure over Taiwan.

In Beijing’s public account, Foreign Minister Wang Yi told Secretary of State Marco Rubio that the two sides should prepare for the next phase of high-level contacts on the basis of equality, respect and reciprocity, while expanding cooperation, managing differences and respecting each other’s core interests.¹ Reuters reported that the call was tied to preparations for the expected Xi-Trump meeting, though China’s official readout did not explicitly confirm the summit.²

That ambiguity is part of the diplomacy. Beijing is signaling that summitry should restore strategic stability and status parity between the world’s two largest economies, while leaving room to press Washington on what China defines as core interests, foremost Taiwan. In Tokyo and Taipei, the same language is being read differently: any perceived softening of U.S. wording on Taiwan could unsettle regional partners that rely on Washington’s deterrent posture.³

Beijing’s message: reset, but on Chinese terms

China’s public line after the Wang-Rubio call emphasized process as much as substance. Wang framed the next stage of engagement around mutual respect, equality, reciprocity and cooperation, alongside the need to manage disputes and avoid undermining core interests.¹

In Chinese diplomatic usage, “core interests” is not a generic phrase. It often signals issues Beijing treats as non-negotiable, including Taiwan, sovereignty claims and the political legitimacy of the Communist Party.

The message suggests Beijing wants the summit to do more than reduce tactical friction. It wants Washington to show that renewed engagement will not be accompanied by what China sees as containment, coercive technology restrictions or support for Taiwan that crosses Beijing’s red lines. Regional reporting has framed the call as likely among the final preparatory steps before Xi’s planned U.S. visit, with Beijing emphasizing strategic stability and controlled competition.⁴

The optics also matter. Reports that Trump plans to greet Xi at Joint Base Andrews before the White House meeting point to a highly choreographed effort to present the visit as a major-power encounter with unusual protocol and symbolic parity.⁸ For Beijing, such gestures can be used domestically and diplomatically to show that Washington is treating China as an equal counterpart rather than a problem to be managed.

Taiwan language becomes the stress point

The most sensitive question is not whether the United States and China can find areas to discuss, but what Washington might say — or avoid saying — about Taiwan to preserve summit momentum.

Reuters reported concern among U.S. allies and partners that Trump could adjust language on Taiwan in ways Beijing would welcome and Tokyo or Taipei would interpret as a weakening of U.S. support.³ Even subtle wording changes can matter. For decades, U.S. policy has rested on a deliberately calibrated framework: recognition of the People’s Republic of China as China’s government, acknowledgment of Beijing’s position on Taiwan, continued unofficial ties with Taipei, and opposition to unilateral changes to the status quo.

For Taiwan, the fear is that summit diplomacy could blur that balance. A senior U.S. senator who chairs the Asia-Pacific subcommittee urged Trump to keep Taiwan policy unchanged and said Washington would not tolerate a forced change in Taiwan’s status.⁶ That message reflects a wider concern in Taipei: that transactional summit bargaining could create uncertainty even if formal U.S. policy remains intact.

Japan’s concerns are strategic as well as political. Taiwan sits close to Japan’s southwestern islands and sea lanes, and Tokyo has increasingly treated a Taiwan contingency as inseparable from Japanese security planning. If Beijing leaves the summit believing Washington has softened its posture, Japanese officials would likely worry not only about Taiwan, but also about the credibility of U.S. commitments across the Western Pacific.³

A broader reset agenda, with alliance costs

The summit is expected to cover more than Taiwan. Artificial intelligence governance has emerged as another likely agenda item, as both governments face pressure to address safety risks and strategic competition in advanced technologies.⁷ That gives Washington and Beijing an opportunity to present the meeting as a pragmatic reset focused on global risks, economic stability and guardrails.

But the alliance-management problem remains. The more Washington emphasizes cooperation with Beijing, the more it must reassure Tokyo, Taipei and other regional partners that cooperation does not mean concession. Conversely, the more Washington repeats hard-edged deterrence language, the harder it may be to produce the stable atmosphere Beijing says it wants.

Hong Kong public broadcaster RTHK, citing Xinhua, reported that Wang and Rubio discussed high-level exchanges one week before the planned leaders’ summit.⁵ That timing underscores how carefully both sides are managing the runway into September 24. China’s readout portrays the call as part of a disciplined process to prepare leader-level diplomacy; Reuters’ reporting places that process within the political reality of a highly anticipated Xi-Trump meeting.²

The test for Washington

The immediate question is whether the summit produces language each side can claim as success without alarming U.S. partners. Beijing is likely to look for signs that Trump accepts a more respectful, less confrontational framework and is willing to treat Taiwan as a stabilizing issue rather than a tool of pressure.

Taiwan and Japan will look for the opposite reassurance: that any reset does not dilute Washington’s opposition to coercion or unilateral changes to the status quo.

That makes the summit less a simple thaw than a three-level diplomatic exercise. Washington must speak to Beijing about stability, to Taipei about continuity, and to Tokyo about deterrence. The words chosen on Taiwan may be only a small part of the formal agenda, but they could determine how the region judges the meeting.
