A U.S. House lawmaker has urged the Defense Department to expand restrictions on research ties with Chinese institutions. According to Reuters, Representative John Moolenaar requested that 58 universities and 62 technology laboratories be added to a list that limits Defense Department funding for collaborations involving designated institutions. The proposed additions include Tsinghua University, a major Chinese research institution whose business-school advisory board has included prominent U.S. technology executives. The request is not itself a finalized restriction, but it highlights growing compliance uncertainty for universities and laboratories that collaborate internationally. Researchers may face more complicated decisions about partners, grants and scientific exchanges even when projects are not directly connected to military applications. Reuters reported on the request.
