U.S. Trade Representative Robert Lighthizer on Monday promised a “thorough investigation” of China’s actions relating to copyright and intellectual property following a directive from President Trump to investigate piracy by the Asian nation.

“The United States has for many years been facing a very serious problem. China industrial policies and other practices reportedly have forced the transfer of vital U.S. technology to Chinese companies. We will engage in a thorough investigation and, if needed, take action to preserve the future of U.S. industry. Thousands of jobs are at stake for our workers and for future generations. This will be one of USTR’s highest priorities, and we will report back to the president as soon as possible,” Lighthizer said.
