The announcement by US Secretary of State Marco Rubio was brief: „The US will revoke visas for Chinese students, including those with connections to the Chinese Communist Party or studying in critical fields.“ Following Rubio’s tweet last week, the official notice on the State Department’s website offered little more clarity – but did include stronger language. Visas should be revoked „aggressively“, it stated, and all future applications from the People’s Republic of China and Hong Kong would be subject to enhanced scrutiny.
