#USChinaTradeTalks The trade and mineral negotiations between the United States and China in London will extend into the second day; Trump is optimistic

LONDON, June 9 (Reuters) - Trade talks between the United States and China are set to extend into a second day in London, as top economic officials from the two largest economies in the world sought to defuse a bitter dispute that has escalated from tariffs to restrictions on rare earths, threatening a shock to the global supply chain and slower economic growth.

The talks at Lancaster House, an ornate mansion of the UK government, concluded on Monday night and will resume at 10 am BST (0900 GMT) on Tuesday, a US source familiar with the negotiations said.

Washington and Beijing are attempting to revive a temporary truce reached in Geneva that had briefly eased trade tensions and calmed the markets.

Since then, the United States has accused China of delaying its commitments, particularly regarding rare earth shipments.

US President Donald Trump, on Monday, gave a positive spin to the talks, saying they were going well and that he was "only receiving good reports" from his team in London.
