A Summit Called "Unforgettable" — But What Was Actually Agreed?
President Donald Trump departed Beijing on May 15, 2026, after two days of meetings with Chinese President Xi Jinping that the American leader described as "very successful, world renowned and unforgettable," and that Chinese state media characterised as "historic" and "a landmark moment in US-China relations." The superlatives on both sides were abundant. The substance, measured against the extraordinary anticipation that had surrounded the summit for weeks, was more incremental — consisting of a handful of concrete commercial agreements, a significant diplomatic alignment on the Strait of Hormuz, a stark Chinese warning about Taiwan, and a mutual commitment to continue talking that was formalised through Trump's invitation for Xi to visit the United States in September 2026. What the summit was not was a moment of transformative geopolitical resolution: it delivered no breakthrough on the Iran war, no formal new tariff agreement, and no softening of either side's fundamental position on the issues that most sharply divide them.
The bilateral meeting at Zhongnanhai — the compound adjacent to the Forbidden City that serves as the seat of China's leadership — lasted two hours and fifteen minutes on May 14. Xi walked down the steps of the Great Hall of the People to greet Trump personally, a gesture of protocol significance in Chinese diplomatic practice. The two leaders were accompanied by senior officials on both sides: China's top diplomat Wang Yi and economic planning head Zheng Shanjie for Beijing, and Secretary of State Marco Rubio and a delegation of sixteen prominent American business executives for Washington — including Nvidia CEO Jensen Huang, Tesla's Elon Musk, Apple CEO Tim Cook, and Boeing CEO Kelly Ortberg. The business delegation's presence in the room underlined the commercial character of Trump's approach to the visit. The following morning, the leaders signed a joint communiqué and Xi accepted Trump's invitation to a White House visit in the autumn, setting the next formal checkpoint for the relationship.
The Boeing Deal: 200 Jets, Not the 500 Many Had Expected
The most publicly highlighted commercial outcome of the summit was China's agreement to purchase 200 Boeing 737 aircraft. Trump announced the deal in a pre-recorded interview with Fox News's Sean Hannity that aired on Thursday evening, saying: "One thing he agreed to today — he's going to order 200 jets. That's a big thing. Boeings." Trump noted, with visible satisfaction, that this figure exceeded the 150 units that the Boeing Company had itself been expecting from the visit. However, the deal fell well short of earlier optimistic projections in financial markets and within the aviation industry: analysts at Jefferies had estimated a potential order of up to 500 aircraft, and pre-summit reporting by several major financial outlets had described the possibility of 600 jets being agreed. Boeing CEO Kelly Ortberg was part of the US delegation in Beijing and was present during the business leaders' meeting with Chinese Premier Li Qiang — yet despite that access, the order confirmed was considerably smaller than what investors had anticipated.
Boeing's share price responded accordingly: the stock fell 4.68 percent on the session in which the deal was announced, declining to $231.38, as markets absorbed the reality that the agreement, while commercially meaningful, was significantly below the level that had been priced in. For Boeing, which has been navigating a prolonged period of regulatory scrutiny, production challenges, and public safety concerns following earlier controversies with the 737 MAX programme, any large Chinese order represents a meaningful positive development. But the gap between expectation and delivery — 200 versus a widely anticipated 500 or 600 — was enough to produce a net negative market reaction on the day of the announcement itself.
Nvidia's H200 Chip Win: The Summit's Most Market-Moving Outcome
While the Boeing headline dominated media coverage, the commercial development that produced the most immediate and powerful market reaction was the US government's approval of Nvidia H200 chip exports to ten major Chinese companies. The decision, announced during the period of the Trump visit to Beijing, directly lifted a restriction that had been one of the most consequential elements of the US government's effort to limit China's access to the most advanced artificial intelligence hardware. Nvidia CEO Jensen Huang — who joined the Beijing delegation as a late addition after Trump personally called him to participate — was described by one commentator as "the walking, talking symbol of the AI race," and his presence alongside Xi and Trump in Beijing sent a clear signal about the direction of American policy on the chip export question even before the formal announcement was made.
Nvidia shares surged 4.4 percent on the day the H200 approval was announced, extending the company's monthly gain to 15 percent and continuing what was by then a six-session winning streak. The VanEck Semiconductor ETF climbed in sympathy. The H200 chip is one of Nvidia's most powerful data centre graphics processing units and is used extensively in the training and inference of large AI models — precisely the technology that China's cloud computing companies, research institutions, and AI development teams most urgently need. The ten Chinese companies cleared to receive the chips include major names in China's technology sector, though the specific recipients were not all publicly named in initial reporting. The approval represents a carefully calibrated concession: the H200, while extremely powerful, is one generation behind Nvidia's most advanced current hardware, giving US policymakers room to argue that national security red lines have not been crossed while still providing a commercially and diplomatically valuable gesture to Beijing.
Xi's Taiwan Warning: The Thucydides Trap at the Great Hall of the People
The most geopolitically significant moment of the summit came in Xi Jinping's opening public remarks, delivered in the formal setting of the Great Hall of the People on Thursday. Xi warned Trump that the United States and China "will have clashes and even conflicts" if the question of Taiwan's status is mishandled — a stark and direct statement of Chinese resolve on what Beijing considers the most sensitive issue in the bilateral relationship. "The Taiwan question is the most important issue in China-US relations," Xi said, according to official Chinese state media. Xi also asked whether the US and China could "transcend the so-called Thucydides Trap" — the concept, popular in foreign policy scholarship, describing how tensions between a rising and an established power have historically tended toward military conflict — and forge a new paradigm for relations between major powers. The use of the Thucydides Trap framing, deployed at precisely the moment when Trump was offering optimism about the bilateral relationship, was widely interpreted as a calibrated reminder of the structural risks embedded in the competition between the two countries.
Secretary of State Marco Rubio, speaking to reporters after the meeting, said US policy toward Taiwan remained "unchanged" and characterised China's raising of the Taiwan issue as routine. "They always raise it on their side. We always make clear our position, and we move on to the other topics," Rubio said. Taiwan's government responded to Xi's remarks by calling China "the sole risk" to regional peace in the Taiwan Strait and reaffirming that the US had repeatedly confirmed its support for Taiwan's security. Trump himself did not directly address Xi's Taiwan comments in his public statements after the summit, focusing instead on the commercial outcomes and the general positivity of the meeting's atmosphere. The White House said US policy on Taiwan was unchanged.
Iran, Hormuz, and the Limits of Chinese Influence
The war in Iran and the blockade of the Strait of Hormuz were central topics of the bilateral meeting, and on this issue the summit produced what both sides were able to frame as a meaningful alignment of positions. A White House official confirmed that "the two sides agreed that the Strait of Hormuz must remain open to support the free flow of energy." Xi reportedly also made clear China's opposition to Iran's attempt to charge tolls on vessels transiting the strait and expressed interest in increased purchases of American energy — a commercial incentive that creates a parallel economic alignment between the US and Chinese positions on the Hormuz question. Trump told Fox News that Xi committed to helping the United States with Iran, though he simultaneously told reporters he did not think the US needed Chinese help with Iran — a characteristic contradiction that left analysts uncertain about exactly what had been agreed behind closed doors.
Yue Su, principal economist for China at the Economist Intelligence Unit, offered a measured assessment: "There are limits to what China can realistically do, as the Iranian regime is operating in survival mode and will prioritize its own interests and agenda above all else." She noted that both sides had described the meeting as a win — a signal of goodwill — but that the fundamental gap in their approaches to the Iran crisis remained wide. China has continued to import Iranian oil throughout the conflict, giving it economic exposure to any disruption of that trade but also giving Tehran reason to value the relationship. Whether that leverage translates into effective Chinese diplomatic pressure on Iran to accept a peace deal remains to be seen in the weeks following the summit's conclusion.
Markets React: Dow Above 50,000, S&P Above 7,500 on Summit Day
Financial markets delivered their verdict on the Trump-Xi summit in real time. On May 14, the day of the bilateral meeting, the S&P 500 climbed 0.77 percent to close above 7,500 for the first time in its history — a new all-time record. The Nasdaq Composite rose 0.88 percent to another record. The Dow Jones Industrial Average gained 370 points, or 0.75 percent, to close at 50,063 — reclaiming the psychologically significant 50,000 level for the first time since the start of the Iran war in late February 2026. Technology stocks, driven by Cisco's blowout earnings and Nvidia's H200 chip clearance news, powered the rally. The S&P 500 and Nasdaq were on pace for their seventh consecutive positive week as of the start of May 15 trading — the longest winning streak for both indices in several years. US futures markets, however, dipped on May 15 morning as investors assessed the gap between the summit's outcomes and the elevated expectations that had preceded it, with Dow futures falling 132 points and S&P futures sliding 1 percent in early pre-market activity.
