Chinese and U.S. officials talked Tuesday and are scheduled to talk again in two weeks, Beijing’s Commerce Ministry said Tuesday in a statement. The next talks will come just days before the United States’ September deadline to institute new tariffs on $300 billion worth of Chinese goods.

Chinese Vice Premier Liu He, the country’s top negotiator, spoke Tuesday with U.S. Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin, the ministry said in a statement. It said the second set of talks will happen over the phone, not in person, in two weeks.
