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.

Monday's U.S.-China trade talks could be about a lot more than just tariffs.
