WASHINGTON (Reuters) - The United States and China have largely agreed on a mechanism to police any trade agreement they reach, including establishing new "enforcement offices," U.S. Treasury Secretary Steven Mnuchin said on Wednesday.

Mnuchin, speaking on CNBC television, said that progress continues to be made in the talks, including a "productive" call with China's Vice Premier Liu He on Tuesday night. The discussions would be resumed early on Thursday, Washington time, he added.

"We've pretty much agreed on an enforcement mechanism, we've agreed that both sides will establish enforcement offices that will deal with the ongoing matters," Mnuchin said, adding that there were still important issues for the countries to address.
