The US says it has revoked the visas of more than 1,000 Chinese students and researchers who have been deemed to be a security risk.
The move follows a proclamation by President Donald Trump in May aimed at Chinese nationals suspected of having ties to the military.
He said some had stolen data and intellectual property but China has not commented.
A state department spokeswoman described those declined a visa as “high-risk graduate students and research scholars.”

Nearly 370,000 students from China enrolled at US universities in 2018-19.
