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 Chinese delegation led by Vice Premier He Lifeng held talks with U.S. Commerce Secretary Howard Lutnick, Treasury Secretary Scott Bessent and Trade Representative Jamieson Greer at Lancaster House, an ornate 200-year-old mansion near Buckingham Palace.

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.
