Trump and Xi try to put a floor under the rivalry
Washington and Beijing have bought themselves more time. They have not resolved the forces pushing them apart.

Donald Trump and Xi Jinping met at the White House on 24 September for their second face-to-face meeting of 2026. The ceremony was elaborate, but the substance was deliberately more modest: keep trade tensions contained, keep talking, and prevent strategic competition between the world's two largest economies from becoming something more dangerous.1
Ahead of the summit, Treasury Secretary Scott Bessent announced on 23 September that the US–China trade truce would be extended by two months, from 10 November to 10 January 2027. That prevents an immediate return to the tariff escalation that dominated the relationship previously, but it does not amount to a comprehensive trade settlement. Disputes over tariffs, Chinese purchases of American goods, rare-earth supplies and technology restrictions remain unresolved.2
That distinction matters. This was less a breakthrough than an attempt to establish a floor beneath the relationship.
The competition hasn't gone away
The economic relationship between the two countries remains enormous. In 2025, the United States exported about $106 billion of goods to China and imported approximately $309 billion, leaving total bilateral goods trade at roughly $415 billion.3
Yet the sources of economic strength behind those numbers are increasingly different.
The United States remains larger when measured by nominal GDP. The IMF's April 2026 forecasts put it at roughly $32.4 trillion in 2026, compared with $20.9 trillion for China, in current US dollars.45
For population, the graphic uses dated 2025 estimates: about 342 million US residents on 1 July, compared with 1.40 billion people in mainland China at year-end. UNIDO estimated China's share of global manufacturing value added at 32% in 2024. This is value added, rather than gross manufacturing output.678
The result is a rivalry in which neither side can easily separate itself from the other. Washington wants to preserve its advantages in advanced technology and reduce strategic dependencies. Beijing wants continued access to global markets while strengthening its own technological and industrial capabilities.
Trade between them has fallen sharply — US goods trade with China was about $415 billion in 2025, down from roughly $584 billion in 2024 — but it remains far too large to describe the two economies as detached.3
AI is becoming part of the relationship
Artificial Intelligence has now joined trade, semiconductors and critical minerals as an issue that Washington and Beijing have to manage directly.
Bessent said on 21 September that the two sides had agreed to establish a formal AI dialogue, including work on an incident line, and would meet again in Shenzhen in about two months. These were plans for further talks; they did not establish that an operational hotline was already in place.9
But the summit also exposed a fundamental difference in approach.
At the UN, Trump rejected international control of advanced AI.10 Xi argued that the two countries have a responsibility to ensure AI remains under human control and serves human interests.11
That makes AI unusual within the wider rivalry. The United States and China are competing intensely to lead the technology, while simultaneously beginning to discuss what happens if increasingly capable systems create risks that neither country can contain alone.
For readers coming from this report's earlier AI section, the connection is difficult to miss: AI governance is no longer only a debate between governments and technology companies. It is becoming part of great-power diplomacy.
Taiwan remains the red line
There was no comparable easing over Taiwan.
According to the Chinese account of the talks, Xi urged Washington to handle Taiwan cautiously and to oppose Taiwanese independence. That account records Beijing’s request; it does not establish that Washington adopted the formulation.1
The language reflects a continuing disagreement over Taiwan’s status and security.
Taiwan remains the issue most capable of transforming US–China competition from an economic and technological contest into a military confrontation.
Xi himself invoked the idea of the “Thucydides Trap” — the theory that conflict can emerge when a rising power challenges an established one — while arguing that such an outcome can be avoided. He called for stronger crisis-prevention mechanisms and regular military dialogue.11
That may ultimately be more important than any individual trade concession.
What actually changed?
Very little about the underlying rivalry.
The United States still wants to protect its technological lead, diversify critical supply chains and constrain Chinese capabilities where Washington considers them a national-security risk.
China still wants greater technological independence, continued access to international markets and recognition of what it regards as its core interests — above all Taiwan.
Rare earths remain a source of Chinese leverage. Technology restrictions remain a source of American leverage. Trade remains both a weapon and a reason for restraint.
What changed in Washington was the willingness to keep those disputes inside a managed relationship.
China's official description is revealing. Beijing says the objective should be a relationship in which “cooperation is the mainstay, competition is kept within proper limits, differences are managed and peace can be expected.”1
Washington would not necessarily describe the relationship in the same terms. But the behaviour of both governments increasingly points towards a similar practical objective:
competition without collision.
The two-month trade extension is therefore not particularly impressive as a trade agreement.
As a mechanism for buying time between two nuclear-armed superpowers competing across economics, technology and security, it matters considerably more.
Context
How did the US and China get here?
For decades, economic integration was expected to make confrontation between Washington and Beijing less likely. Instead, the relationship evolved from commercial partnership into strategic competition — encompassing tariffs, semiconductors, Taiwan, military power, critical minerals and now Artificial Intelligence.
