#USChinaTradeTalks U.S.-China trade talks were set to extend to a second day in London as top economic officials from the world's two largest economies sought to defuse a bitter dispute that has widened from tariffs to restrictions over rare earths, threatening a global supply chain shock and slower economic growth.

Talks at Lancaster House, an ornate UK government mansion, wrapped for the night on Monday and were set to resume at 10 a.m. BST (0900 GMT) on Tuesday, a U.S. source familiar with the negotiations said.
