Three Key Points
・The U.S. and China presented the Beijing summit as an effort to build a “constructive and strategically stable” relationship, but deep tensions remain over Taiwan, AI semiconductors and energy security.
・The United States needs China’s cooperation on Iran and the Strait of Hormuz, while also trying to hold firm on Taiwan and advanced technology controls.
・The presence of senior U.S. officials and major corporate leaders reflected how diplomacy, national security, finance and industrial policy have become inseparable in U.S.-China relations.
News
U.S. President Donald Trump and Chinese President Xi Jinping met in Beijing on May 14. According to the Chinese side, Xi said the two countries should build a “constructive and strategically stable” relationship. He also raised the question of whether the United States and China can avoid the so-called “Thucydides Trap” and create a new model for relations between major powers.
Taiwan was also a major focus of the meeting. Xi described the Taiwan issue as one of the most important questions in U.S.-China relations and warned that mishandling it could lead the two countries toward clashes or even conflict.
The U.S. readout, meanwhile, placed greater emphasis on the Strait of Hormuz, energy flows and trade cooperation. Washington said Xi had expressed interest in buying more U.S. oil as a way to reduce China’s dependence on the Strait of Hormuz. However, China’s official account did not prominently mention U.S. oil purchases, showing a difference in how the two sides presented the meeting.
The U.S. delegation reportedly included Secretary of State Marco Rubio, Treasury Secretary Scott Bessent, Defense Secretary Pete Hegseth and senior trade officials. Major business leaders, including Nvidia CEO Jensen Huang, Elon Musk and Apple CEO Tim Cook, were also reported to have joined the visit.
The summit had been delayed amid instability linked to the Iran conflict and the Strait of Hormuz. The United States and China entered the talks with unresolved tensions over Taiwan, advanced semiconductors, energy security and the Middle East, while still keeping diplomatic channels open.
Background
What Is the Thucydides Trap?
The “Thucydides Trap” refers to the idea that when a rising power challenges an established power, fear, mistrust and miscalculation can make war more likely.
The term comes from the ancient Greek historian Thucydides, who wrote about the rivalry between rising Athens and established Sparta. In modern geopolitics, the concept is often used to describe the relationship between China as the rising power and the United States as the established power.
By using this phrase, Xi Jinping was signaling that conflict between the United States and China is not inevitable. The message was that great powers can avoid war if they manage competition and prevent strategic miscalculation.
At the same time, the phrase also carries a political message from Beijing. China sees U.S. support for Taiwan, advanced semiconductor controls and alliance-building in Asia as part of a broader effort to contain China’s rise. In that sense, Xi’s reference to the Thucydides Trap was also a warning that Washington should not turn competition into containment.
Why Taiwan Remains the Most Dangerous Flashpoint
Taiwan remains the most immediate military flashpoint in U.S.-China relations.
For the United States, support for Taiwan, including arms sales, is viewed as a way to preserve deterrence in the Taiwan Strait. The logic is that Taiwan must be able to defend itself well enough to make the use of force by China too costly.
For China, U.S. arms sales to Taiwan are seen very differently. Beijing views them as support for separatism and as foreign interference in what it considers an internal matter.
It has not been publicly confirmed how specifically Taiwan arms sales were discussed during the summit. But they remain an important part of the background. Washington sees them as deterrence. Beijing sees them as a challenge to sovereignty. This gap in perception is what makes Taiwan such a dangerous issue.
Taiwan is also tied to the global semiconductor supply chain. Instability in the Taiwan Strait would not only affect regional security but also the world economy, especially advanced chip production. That is one reason the Taiwan issue carries weight far beyond the island itself.
Why Iran and the Strait of Hormuz Shadowed the Summit
The Strait of Hormuz is one of the world’s most important energy chokepoints. A disruption there would affect oil prices, natural gas markets, shipping costs and inflation.
The worsening situation around Iran created pressure on the United States. If Middle East tensions push up energy prices, the consequences can quickly spread into domestic politics through inflation and fuel costs. Washington therefore had an interest in China using its influence with Iran and in helping stabilize energy flows.
China also has reason to avoid a crisis in the Strait of Hormuz. It imports large amounts of energy from the Middle East, and a prolonged disruption would damage its own economy. For Beijing, the crisis creates both leverage against Washington and a risk to China’s own energy security.
This created a complicated situation for the United States. Washington wants to be firm with China on Taiwan and semiconductors, but on Iran and the Strait of Hormuz it cannot ignore China’s influence. That contradiction shaped the atmosphere around the meeting.
What the Corporate Delegation Revealed
The presence of Nvidia CEO Jensen Huang symbolized the central role of AI chips in U.S.-China competition.
American companies want access to the Chinese market. But the U.S. government worries that advanced chips could strengthen China’s military capabilities and AI systems. Nvidia sits directly at the center of that tension.
Elon Musk’s presence pointed to Tesla, electric vehicles, AI and supply chains. Tim Cook’s presence reflected Apple’s deep ties to China as both a manufacturing base and a consumer market.
The corporate delegation showed U.S. industrial power. But it also revealed the limits of economic decoupling. American companies still need China as a market, production base and supply-chain partner.
From China’s perspective, this is useful. Beijing can argue that even if the U.S. government takes a hard line, major American companies still need China. From Washington’s perspective, the challenge is to open opportunities for U.S. business while limiting national security risks.
Analysis
A Summit About Managing Rivalry, Not Ending It
The Beijing summit was not a simple moment of reconciliation. It was a meeting about managing rivalry.
Both sides used the language of stability and avoiding conflict. But the core disputes remain: Taiwan, semiconductors, AI, energy security and the Middle East.
What the two countries appeared to test was not how far they could cooperate, but where the danger lines are. The United States needs China’s cooperation on Iran and the Strait of Hormuz, but does not want to retreat on Taiwan or advanced technology controls. China also wants to avoid energy disruption, but wants Washington to reduce pressure on Taiwan and technology.
The summit’s main function was therefore not to resolve U.S.-China rivalry, but to keep that rivalry within manageable limits.
The United States Cannot Cut China Off Completely
For Washington, China is both its main strategic competitor and a country it cannot simply ignore.
On Iran and the Strait of Hormuz, China’s influence matters. Beijing has ties with Tehran and deep energy interests in the Middle East. If the United States wants to reduce regional escalation, treating China only as an enemy makes diplomacy harder.
But there are also issues where Washington cannot easily compromise. Taiwan, advanced AI chips and military-use technologies sit close to national security. If export controls are relaxed too far, China’s military and AI capabilities could grow. If support for Taiwan appears to weaken, U.S. allies and partners may question American deterrence.
This double constraint makes U.S. policy difficult. Washington needs China on some issues, but it cannot afford to look weak on others.
China Talks Stability While Seeking U.S. Concessions
China emphasized stability, major-power cooperation and avoiding the Thucydides Trap.
That language sounds constructive. But for Beijing, stability also means something more specific: the United States should accept China’s rise and reduce pressure on Taiwan, technology and trade.
Xi’s strong warning on Taiwan was therefore central. China does not view U.S. arms sales to Taiwan as ordinary defense cooperation. It sees them as a challenge to sovereignty and as support for separatism.
China can also use U.S. corporate dependence on its market as leverage. Companies like Nvidia, Tesla and Apple still have major business interests in China. That allows Beijing to argue that the U.S. economy cannot fully separate from China, even if Washington’s strategic language becomes more confrontational.
Corporate Leaders Showed How Hard Decoupling Really Is
The corporate presence at the summit reflected a basic reality: the U.S. and Chinese economies remain deeply connected.
The U.S. government is tightening technology controls and placing national security at the center of economic policy. But U.S. companies still see China as a huge market, a production base and part of their supply chains.
Nvidia wants access to Chinese demand, but AI chips are at the center of U.S.-China strategic competition. Tesla depends on China as both a market and manufacturing hub. Apple remains heavily tied to China through supply chains and consumer sales.
The United States wants to limit China’s rise in sensitive technologies. But American companies still want to profit in China. China dislikes U.S. pressure, but it does not want to push out every major American company either.
This interdependence makes a complete rupture unlikely. At the same time, it creates new security concerns.
Influence Operations Are Also Part of the Rivalry
Just before the summit, the U.S. Department of Justice announced that Arcadia Mayor Eileen Wang had been charged with acting as an illegal agent of the Chinese government and had agreed to plead guilty.
This was not a typical military espionage case. It involved allegations that she promoted the interests of the Chinese government inside the United States without properly registering as a foreign agent.
The timing was symbolic. The United States was preparing to hold high-level talks with China and explore cooperation on energy and trade. At the same time, Washington signaled that it would continue to confront Chinese influence operations at home.
For the United States, dialogue with China is necessary. But domestically, Washington also needs to avoid the appearance of being soft on Beijing. Showing cooperation and resistance at the same time has become part of U.S. China policy.
The Risk for Japan and Taiwan
For Japan and Taiwan, the danger in U.S.-China relations is not only confrontation.
If U.S.-China tensions escalate sharply, the Taiwan Strait and East Asia become more unstable. But if the two great powers move toward a large strategic bargain, there is also concern that regional security could become a bargaining chip.
Taiwan sits at the center of this dilemma. If the United States reduces support for Taiwan, deterrence against China could weaken. If Washington pushes too aggressively, the risk of military escalation could rise.
For Japan, stability in the Taiwan Strait is directly tied to national security and the economy. It affects semiconductor supply, maritime routes, the defense of Japan’s southwestern islands and the credibility of the U.S.-Japan alliance.
The summit showed that Washington and Beijing are trying to manage their rivalry. But that management does not automatically reassure Japan or Taiwan. When great powers speak about “stability,” smaller and allied states must ask whose stability is being prioritized.
Conclusion
The Trump-Xi summit in Beijing was publicly framed around stability and cooperation.
But beneath that language, the meeting revealed deeper tensions over Taiwan, AI semiconductors, energy security, the Iran conflict, U.S. corporate dependence on China and concerns over Chinese influence operations inside the United States.
The United States needs China’s cooperation on Iran and the Strait of Hormuz, but it also wants to hold the line on Taiwan and advanced technology. China speaks about avoiding the Thucydides Trap, while also seeking U.S. acceptance of its rise and a reduction of pressure on Taiwan and technology.
The presence of major corporate leaders showed that the two economies cannot be easily separated. At the same time, the Arcadia mayor case showed that Washington is still willing to confront Chinese influence efforts at home.
The real meaning of the summit was not that the United States and China had reconciled. It was that both sides were testing each other’s weaknesses and red lines while trying to keep rivalry within manageable limits.
For Japan and Taiwan, the key question is not only whether the United States and China can avoid conflict. It is also whether a future U.S.-China bargain would protect or sideline the security interests of countries most exposed to the consequences.
