U.S. and Chinese trade negotiators have said they plan to meet again in early September, after the latest round of negotiations ended with few signs of concrete progress.

U.S. officials including Treasury Secretary Steven Mnuchin and Trade Representative Robert Lighthizer wrapped up talks with their Chinese counterparts, including Vice Premier Liu He, on Wednesday afternoon in Shanghai. In a statement, The White House specified Washington as the location for the next round of talks, and said the sides held "constructive" talks this week over "forced technology transfer, intellectual-property rights, services, non-tariff barriers, and agriculture."

"The Chinese side confirmed their commitment to increase purchases of United States agricultural exports," according to the U.S. statement. The negotiators from Beijing and Washington discussed increasing China's import of agriculture products from the U.S. based on its needs and favorable conditions from America, state-run news agency Xinhua reported.
