Top US officials are preparing a trip to China before the end of July in a bid to reignite talks to resolve the trade dispute between the world’s two largest economies, administration officials said on Tuesday. 

The resumption of face-to-face negotiations between Washington and Beijing has been widely expected after Donald Trump, the US president, and Xi Jinping, the Chinese president, struck a truce at the G20 summit in Japan last month, refraining from further tariffs and setting the stage for more discussions. 

However, a series of skirmishes over goodwill gestures meant to pave the way for the talks to restart — on Chinese purchases of agricultural goods and the US ban on doing business with Huawei, the Chinese telecommunications company — had cast doubt on a quick return to the negotiating table.
