The London negotiations, following on from a first round in Geneva last month, aim to quell renewed tariff tensions between Washington and Beijing.

New York's blue-chip Dow index was lower, while the broader S&P 500 was flat and the tech-heavy Nasdaq rose modestly in late morning trading.

Asian shares closed up on hopes of a deal, and catching up with Wall Street from Friday, when US jobs data suggested the American economy was doing well, for now.

The dollar, however, dipped amid persistent fears of higher US inflation in the pipeline from Trump's generalised tariffs weighing on it.

London, Paris and Frankfurt indices all closed lower.

While the US economy has been showing resilience, official data on Monday showed China's exports to the United States last month grew at a slower pace than expected, even as they picked up to the EU and Asia.

The US-China talks took place following a call between US President Donald Trump and Chinese President Xi Jinping last Thursday. They sought a de-escalation after each had accused the other of violating terms of a tariffs reprieve struck in Geneva in mid-May.

"Some kind of accord would be welcome, but they might even be happy if the two sides merely agree to keep talking," said Chris Beauchamp, chief market analyst at online trading platform IG.

"To jaw jaw is better than to (trade) war war, it seems," he said a note to clients.

The US side in London on Monday was being led by Treasury Secretary Scott Bessent, Commerce Secretary Howard Lutnick and Trade Representative Jamieson Greer, while Vice Premier He Lifeng headed the Chinese team.

Their meeting was helped by news that Beijing on Saturday approved some applications for rare-earth exports, while US aviation giant Boeing is to start sending commercial jets to China for the first time since April.

Easing China's export controls on rare-earths was key for Washington, "while China wants the US to rethink immigration curbs on students, restrictions on access to advanced technology including microchips, and to make it easier for Chinese tech providers to access US consumers," said Kathleen Brooks, research director at XTB.

"The outcome of these discussions will be crucial for market sentiment," she said.

The dollar's weakness came as economists warned that Trump's tariffs on most of the world could reignite inflation, and as the US Federal Reserve weighs whether to lower interest rates.

In corporate news, entertainment giant Warner Bros. Discovery announced plans to split into two publicly traded companies, sending its share price higher by more than seven percent.

One would be a Streaming and Studios company covering film and TV production and catalogues, and the other a Global Network company with television brands including CNN and Discovery, and free-to-air channels in Europe.

US semiconductor maker Qualcomm also announced it was buying a UK firm, Alphawave, for $2.4 billion as demand for database infrastructure heated up from demand in the AI sector.

Alphawave shares in London jumped almost 19 percent.

Qualcomm's shares rose 3.6 percent in New York.
