WASHINGTON: The United States said on Friday (May 22) it would add 33 Chinese firms and institutions to an economic blacklist for helping Beijing spy on its minority Uighur population or because of ties to weapons of mass destruction and China's military.

The US Commerce Department's move marked the Trump administration's latest efforts to crack down on companies whose goods may support Chinese military activities and to punish Beijing for its treatment of Muslim minorities. It came as Communist Party rulers in Beijing on Friday unveiled details of a plan to impose national security laws on Hong Kong.
