Washington, Dhu-AlQa'dah 26, 1438, Aug 18, 2017, SPA -- The United States on Friday formally launched an investigation into China's alleged theft of U.S. intellectual property, a widely expected move following a call from President Donald Trump earlier this week to determine whether one was needed. After consulting with stakeholders and other government agencies, I have determined that these critical issues merit a thorough investigation," U.S. Trade Representative Robert Lighthizer, the nation's top trade negotiator, said in a statement. -- SPA 23:47 LOCAL TIME 20:47 GMT www.spa.gov.sa/w469078
