China and the US held “productive” trade talks in Beijing on Wednesday and will continue discussions in Washington next week, U.S. Treasury Secretary Steven Mnuchin said.

Mnuchin, along with U.S. Trade Representative Robert Lighthizer, held a day of discussions, before Chinese Vice Premier Liu He goes to Washington next week for another round of talks in what could be the end game for negotiations.

“Ambassador Lighthizer and I just concluded productive meetings with China’s Vice Premier Liu He. We will continue our talks in Washington, D.C. next week,” Mnuchin wrote on his Twitter account.
