High-level delegations from the United States and China are meeting in London to try and shore up a fragile truce in a trade dispute that has roiled the global economy.

Top U.S. and Chinese officials will resume trade talks for a second day in London on Tuesday, hoping to secure a breakthrough over export controls for goods such as rare earths that have threatened a global supply chain shock and slower economic growth.

A new round of trade negotiations between the United States and China has started in London, with both sides trying to preserve a fragile truce brokered last month.
