U.S. District Chief Judge James Boasberg has temporarily blocked the Pentagon from designating Chinese biotech giant WuXi AppTec Co. as a Chinese military company, ruling that the government lacked sufficient evidence and repeatedly misread facts. The designation had acted as a "scarlet letter," causing customers to cancel contracts. WuXi AppTec, which derives 70% of its revenue from the U.S. and has a majority-U.S. citizen leadership, welcomed the injunction as relief from immediate commercial harm.
