The motorcade that departed the White House on Wednesday contained a Chinese delegation led by Vice Premier Liu He, who has led Chinese trade negotiations in recent weeks as the U.S. and China attempt to resolve their trade dispute.

Chinese officials are expected to return to the White House tomorrow for another session of talks.

Last month, the president announced that the U.S. would hold off on a proposed tariff hike to 25 percent on Chinese goods in the hopes of reaching a deal with the Chinese government in the coming months.
