US and China extend trade truce through January - critical summary review

Since 2018, the United States and China have been running a trade war: each side taxes the other's goods, each side restricts what the other can buy. The two economies are the largest in the world, and their fight does not stay between them. It shows up in the price of cars, in what American farmers can sell, in which computer chips reach which companies, and in who controls the minerals that go into phones, electric motors and defence equipment.

Since last year, that fight has been paused rather than settled. A temporary agreement, struck at a summit in South Korea in October 2025 and known as the Busan Agreement, lowered the tariffs each side had piled on the other, paused new trade restrictions, and got Beijing to loosen its export controls on rare earths in exchange for the US cutting some duties. China also agreed to buy American farm goods and 200 Boeing aircraft. That truce had an expiry date: 10 November.

That is the backdrop against which this week's news arrives.

What the two sides were actually arguing about

The deal on the table is not one deal. It is a set of pressure points each side controls.

Washington restricts China's access to the most advanced artificial intelligence chips and the equipment to make them, and it has accused Chinese labs of "distillation", training their models on the output of more advanced American systems. Beijing rejects the accusation and says the practice is widespread, including among US firms.

Beijing's main lever is rare earths. China placed seven rare-earth elements under export controls last year, and according to the US Geological Survey it accounted for more than 70% of global rare-earth mining and more than 87% of refining and production in 2024. The effect was immediate: Ford halted Explorer production in Chicago for a week over magnet shortages, and Japanese and European auto suppliers shut lines waiting for materials.

Both sides are also weighed down by things outside trade. Taiwan, which China claims as its territory. The US-Israel war on Iran, where China is Tehran's biggest oil buyer. And the arrival of AI as a summit-level subject for the first time.

Red carpet, B-1 bombers and a state dinner full of tech CEOs

Xi landed at Joint Base Andrews in Maryland on Wednesday evening, his first state visit to Washington in more than a decade. Trump and Melania Trump went to the airport to meet him, which American presidents do not normally do. According to US media, it was the first time in 11 years a US president had greeted a foreign leader at that base.

There was a 100-foot red carpet, a 21-person honour guard, the two national anthems, children with flowers, and two B-1 bombers overhead. The Associated Press noted the scene echoed the extra-long carpet rolled out for Vladimir Putin at an air base in Alaska in August 2025. Thursday's White House ceremony was set to include nearly 500 military personnel and another flyover, and the day was to end with a state dinner whose guest list included Tim Cook of Apple, Jensen Huang of Nvidia, Sam Altman of OpenAI, Jeff Bezos, Elon Musk, Sundar Pichai and Michael Dell.

The expectations underneath the pageantry were low. "Nobody is using the term 'deliverables'," said Bonnie Glaser of the German Marshall Fund, a US think tank, to the Guardian. Amanda Hsiao, China director at the political risk consultancy Eurasia Group, told the same paper it would be "yet another summit that is high on positive vibes and relatively low ambition in terms of substance". The May summit in Beijing, where both sides announced a "constructive strategic stability", had produced little concrete.

The result: two more months, not a grand bargain

The concrete outcome came before the leaders even sat down. Treasury Secretary Scott Bessent told Fox News on Wednesday that the Busan Agreement, due to expire on 10 November, would be extended to 10 January. Two months.

Bessent said he had met Chinese Vice-Premier He Lifeng to "see if we could do a bigger deal as opposed to just a series of smaller things", and said earlier that the US was "fine with either continuing" the truce or "examining a bigger deal".

Two months is short, and analysts read it as deliberate. "This is less about buying two months of calm than making China earn the next extension," Craig Singleton of the Foundation for Defense of Democracies told the Associated Press. Wendy Cutler, a former US trade negotiator now at the Asia Society Policy Institute, told the same agency the extension was "way shorter than China had hoped for" and "underscores that the United States is still concerned about China's full implementation of its commitments under the truce, particularly with respect to critical mineral exports and agricultural purchases".

Those doubts have names. Senator Tammy Duckworth said at an event at the Center for American Progress that of the Busan commitments, "they promised the purchase of 200 Boeing aircraft and $17bn in agricultural products. Neither one of those has come to pass."

AI: Trump wants to win the race, Xi wants rules

For the first time, artificial intelligence was near the top of a US-China summit agenda, and the two positions barely touch.

Trump's line has been consistent. "Whoever wins AI, wins," he has said repeatedly, and he has pushed back hard against calls to slow development. Xi, meanwhile, has repeatedly called for greater regulation and a global framework, and has pushed Chinese companies toward cheaper open-source models that other countries can adapt, positioning China as the alternative to the closed systems of OpenAI and Anthropic.

The one concrete step is modest. After meeting He Lifeng in New York, Bessent said the US had proposed a "notification mechanism" for AI incidents serious enough to touch national security. "Moving from opacity to greater transparency between the world's first and second largest AI powers is very important," he said.

The timing was striking. On Wednesday, the UN Security Council held a session on AI. Yoshua Bengio, one of the founders of modern AI research, told the council the risks were "real and imminent" and that the body "faces an unprecedented threat". Dario Amodei of Anthropic said that if managed poorly, "AI could be a risk to humanity as a whole". Sam Altman said systems "could advance faster than our institutions, concentrate power in few hands, or make decisions we cannot understand or control". France, the United Kingdom and China all backed international cooperation mechanisms. Michael Kratsios, the White House science adviser, repeated Trump's position: no reason to pause or restrict AI with global rules.

What was left unresolved

Taiwan. A $14 billion US arms package for Taiwan, approved by Congress, has been on hold for months. After the Beijing summit in May, Trump said he was holding it in abeyance and called it a "very good negotiating chip". Beijing is expected to press him to kill it outright. The US is reportedly considering delaying further sales until after the APEC and G20 summits later this year.

Rare earths and soybeans. Both were on the table again in the weekend talks, and both are the reason the extension is short rather than long.

Distillation. In July, Bessent said the administration had found "watermarks of our US large language models on many of the Chinese models" and called it "unacceptable". Beijing's position has not moved.

Prisoners. The State Department has designated two US citizens, Youlin Chen and Min Zin, as wrongfully detained in China, and Trump was expected to raise their cases. Ziba Murat, whose mother Dr Gulshan Abbas was sentenced to 20 years after disappearing from her home in September 2018, told Fox News Digital she hoped the president would raise hers: "I know that if he knows about this case, he will care about this case."

What to watch between now and 10 January

The extension turns the next few months into a test with a date on it. Whether China delivers the agricultural purchases and rare-earth flows it committed to at Busan is the specific thing Cutler and Singleton say Washington is measuring, and the short window is how it is measuring it.

Watch the $14 billion Taiwan package. If Trump advances it, the negotiating chip is spent. If it keeps slipping past APEC and the G20, that says something about what is being traded for what.

Watch whether the AI notification mechanism ever gets used. It is currently a proposal announced by one side after a bilateral meeting, with no public detail on how an incident would be verified. Aalok Mehta of the Center for Strategic and International Studies told CNBC that any cooperation depends on verification tools, because "policymakers won't be inclined to take their counterparts just on their word".

And watch the calendar. Trump and Xi are expected to meet again at the APEC summit hosted by China and at the G20 that Trump will host in Miami in December. Three meetings in a year between leaders who, twelve months ago, were escalating tariffs and export controls against each other is itself the change. Whether anything under the ceremony moves is what the January deadline will show.
