Trump Administration Tightens Rules on China's Use of U.S. Technology

The Trump administration is tightening rules to prevent China from obtaining advanced U.S. technology for commercial purposes and then diverting it to military use, several sources told Reuters. Three measures agreed to by senior U.S. officials in a meeting, but not finalized, would introduce hurdles that could be used to stop Chinese companies from buying certain optical materials, radar equipment and semiconductors, among other things, from the United States.
