US and Chinese deputy-level negotiators held a "very constructive" teleconference on Wednesday August 21st, Reuters reported.
Trump administration is still planning for a round of in-person talks in September, White House economic adviser Larry Kudlow said.
He added that trade talks under way this week between Japanese Economy Minister Toshimitsu Motegi and US Trade Representative Robert Lighthizer were yielding great progress on agriculture and telecoms issues.
"The deputies' call was quite constructive and this may lead to a meeting of the principals here in Washington DC," Kudlow said, adding that the deputies had agreed to another conference call. He declined to comment on specifics of the discussion.
"They are working through some of the key issues. And then they will pass on a recommendation to the principals," he said.
