Trump ordered US trade officials UU present a WTO case challenging Chinese technology licenses. He proposed 25 percent tariffs on Chinese products, including aerospace, communications technology and machinery, and said Washington will intensify restrictions on Chinese investment in key sectors of US technology.
Trump administration officials identified 1,300 product lines valued at approximately $ 48 billion as potential targets. That list will be open to a 30-day comment period for companies.
