The United States and China have signed a "trade deal" after a more than month-long trade war between the world's two largest economies, the White House has said.

The pair had been negotiating in Geneva, Switzerland, for two days - and on Sunday afternoon, a statement from Donald Trump's office said that a "deal" had been struck.

American trade representative Jamieson Greer called the talks "very constructive" and said the deal would help the US work towards resolving a "national emergency".

"Just remember why we're here in the first place," Greer said. "The United States has a massive $1.2trillion trade deficit, so the President declared a national emergency and imposed tariffs, and we're confident that the deal we struck with our Chinese partners will help us to work toward resolving that national emergency".

But his statement - alongside one from US Treasury Secretary Scott Bessent - has raised eyebrows after not including any details of the deal.

A "complete briefing" will follow tomorrow morning, Bessent said.
