U.S. lawmakers and national security officials are increasingly alarmed that long-standing research ties between the U.S. and China could give China an advantage when it comes to developing new military technology. Members of Congress say China has exploited American colleges and universities. They have proposed new rules to restrict federally funded research partnerships with universities in China that also work with the Chinese military. They've also expressed concerns that U.S. universities could be targeted by foreign spies eager to steal research secrets, highlighting the need for greater cybersecurity measures.
