Donald Trump has described crucial trade talks with Chinese President Xi Jinping as “amazing” – and says he will visit Beijing in April.

The leaders of the world’s two biggest economies met in South Korea as they tried to defuse growing tensions – with both countries imposing aggressive tariffs on exports since the president’s second term began.

Catch up on Trump-Xi meeting

Aboard Air Force One, Mr Trump confirmed tariffs on Chinese goods exported to the US will be reduced, which could prove much-needed relief to consumers.

It was also agreed that Beijing will work “hard” to stop fentanyl flowing into the US.

Semiconductor chips were another issue raised during their 100-minute meeting, but the president admitted certain issues weren’t discussed.

“On a scale of one to 10, the meeting with Xi was 12,” he told reporters en route back to the US.

Xi a ‘tough negotiator’, says Trump

The talks conclude a whirlwind visit across Asia – with Mr Trump saying he was “too busy” to see Kim Jong Un.

However, the president said he would be willing to fly back to see the North Korean leader, with a view to discussing denuclearisation.

Mr Trump had predicted negotiations with his Chinese counterpart would last for three or four hours – but their meeting ended in less than two.

The pair shook hands before the summit, with the US president quipping: “He’s a tough negotiator – and that’s not good!”

It marks the first face-to-face meeting between both men since 2019 – back in Mr Trump’s first term.

There were signs that Beijing had extended an olive branch to Washington ahead of the talks, with confirmation China will start buying US soybeans again.

American farmers have been feeling the pinch since China stopped making purchases earlier this year – not least because the country was their biggest overseas market.

Chinese stocks reached a 10-year high early on Thursday as investors digested their meeting, with the yuan rallying to a one-year high against the US dollar.

Analysis: A fascinating power play

Sky News Asia correspondent Helen-Ann Smith – who is in Busan where the talks took place – said it was fascinating to see the power play between both world leaders.

She said: “Trump moved quickly to dominate the space – leaning in, doing all the talking, even responding very briefly to a few thrown questions.

“That didn’t draw so much as an eyebrow raise from his counterpart, who was totally inscrutable. Xi does not like or respond well to unscripted moments, Trump lives for them.”

Is Trump preparing for war with Venezuela?

On Truth Social, Mr Trump had described the summit as a gathering of the “G2” – a nod to America and China’s status as the world’s two biggest economies.

While en route to see President Xi, he also revealed that the US “Department of War” has now been ordered to start testing nuclear weapons for the first time since 1992.

Some of the world’s biggest tech giants reported quarterly earnings on Wednesday – with a mixed bag of results as fears grow that a bubble is forming in artificial intelligence.

Microsoft revealed that its spending on AI infrastructure hit almost $35bn (£26.5bn) in the three months to the end of September, a sharp rise compared with the year before.

Despite revenue jumping 18% and net income rising 12%, shares plunged by close to 4% in after-hours trading, with investors concerned about the mounting costs of sustaining the boom.

Microsoft’s vice president of investor relations Jonathan Neilson said: “We continue to see demand which exceeds the capacity we have available.

“Our capital expenditure strategy remains unchanged in that we build against the demand signal we’re seeing.”

Big Tech is facing increasing pressure to show returns on the massive AI investments they’re making, against a backdrop of soaring valuations and limited evidence of productivity gains.

Microsoft became the world’s second most valuable company this week thanks to its 27% stake in OpenAI, the creator of ChatGPT.

Its market capitalisation surged beyond $4trn (£3trn) at one point, but that psychologically significant threshold is now in doubt because of recent selloffs.

Alphabet makes history

Last night’s results weren’t all doom and gloom – with shares in Google’s parent company surging by 6% in after-hours trading.

Alphabet has also set out aggressive spending ambitions, but placated investors thanks to an impressive set of results that surpassed analysts’ expectations.

Total revenue for the quarter stood at a staggering $102.35bn (£77bn), with the search giant’s advertising unit remaining robust despite growing competition.

But concerns linger that Alphabet’s dominance in search could be undermined by AI startups, with OpenAI recently unveiling a browser designed to rival Google Chrome.

Hargreaves Lansdown’s senior equity analyst Matt Britzman shrugged off this threat – and believes the company is “gearing up for long-term AI leadership”.

He said: “Alphabet just delivered its first-ever $100bn quarter, silencing the doubters with standout performances in both Search and Cloud.

“AI Overviews and AI Mode are clearly resonating with users, helping to ease fears that Google’s core search business is under threat from generative AI.

“With ChatGPT’s recent browser demo falling short of a game-changer, Google looks well-placed to put up a strong defence as gatekeeper to the internet.”

Meta faces a mauling

Meta – the parent company of Facebook, Instagram, and WhatsApp – saw its shares tumble by as much as 10% in after-hours trading.

Mark Zuckerberg’s tech empire anticipates “notably larger” capital expenses next year as it ramps up investments in AI and goes on a hiring spree for top talent.

Net income in the third quarter stood at $2.7bn (£2bn) and suffered an eye-watering $16bn (£12bn) hit because of Donald Trump’s “Big Beautiful Bill”.

Meta was late to the party on AI but has now doubled down on this still-nascent technology – setting an ambition to achieve superintelligence, a milestone where machines could theoretically outthink humans.

The social networking giant continues to benefit from its massive user base, and expects fourth-quarter revenues of up to $59bn (£44bn).

The US central bank has cut interest rates for the second time this year in a move consistently sought by President Trump.

Rates were brought down by a quarter of a percentage point to 3.75%-4%. Unlike the UK, the US interest rate is a range to guide lenders rather than a single percentage.

The Federal Reserve, known as the Fed, has opted for the cut despite the absence of economic announcements due to the government shutdown.

Latest employment figures were not published, as all non-essential functions of government are frozen over the inability of Republican and Democratic legislators to agree on a spending package.

The absence of these figures makes it trickier for the Fed to assess the state of the economy and meet its dual mandate to keep inflation steady and maintain maximum employment.

Data on price rises, however, showed inflation hit 3% in September, one percentage point above the Fed’s 2% target but lower than anticipated by economists.

The fact that concerns over spiralling inflation, fuelled by Mr Trump’s tariff-induced trade war, have not materialised, has facilitated the cut.

Interest rates had been held amid warnings from Fed chair Jerome Powell that the US economy would grow less and goods would become more expensive due to hiked taxes on imports and the associated disruption in supply.

Mr Powell and the Fed in general have, as a result, been the subject of Mr Trump’s ire. The president sparked a crisis over the Fed’s independence when he moved to remove rate-setter Lisa Cook from her post at the Federal Reserve on alleged mortgage fraud grounds, which she denied.

Before the first interest rate drop of his term, in September, Mr Trump had threatened to remove Mr Powell, calling him a “stupid person” and saying he “should be ashamed”. The animosity comes despite Mr Trump appointing Mr Powell during his first presidential term.

What next?

The prospect of an interest rate cut was one of the factors boosting US and European stock markets in the days running up to the vote, with major stock indexes reaching record highs. Further increases are likely to be seen due to the decision.
