The U.S. and China ended high-stakes trade talks on a positive note on Sunday, with U.S. officials touting a "deal" to reduce the U.S. trade deficit, while Chinese officials said the sides had reached "important consensus" and agreed to launch another new economic dialogue forum.

China has criticised a trade deal between the UK and US that could be used to squeeze Chinese products out of British supply chains, complicating London’s efforts to rebuild relations with Beijing.

The uncertainty also means companies are less willing to make new investments.
