Trump administration to 'aggressively' revoke visas of Chinese students

US President Donald Trump's administration says it will "aggressively" revoke the visas of Chinese students studying in the US.

Secretary of State Marco Rubio said in a statement the move would include "those with connections to the Chinese Communist Party or studying in critical fields".

Visa criteria will also be revised to "enhance scrutiny" of future visa applicants from China and Hong Kong, Rubio added.

Relations between Beijing and Washington have plummeted in recent months as a tit-for-tat trade war erupted between the two superpowers sparked by Trump's tariffs.

On Monday, Rubio, who is America's top diplomat, ordered US embassies around the world to stop scheduling appointments for student visas as the state department prepares to expand social media vetting of such applicants.

Estimates indicate there were around 280,000 Chinese students studying in the US last year.

Rubio said in Wednesday's statement: "Under President Trump's leadership, the US State Department will work with the Department of Homeland Security to aggressively revoke visas for Chinese students, including those with connections to the Chinese Communist Party or studying in critical fields.

"We will also revise visa criteria to enhance scrutiny of all future visa applications from the People's Republic of China and Hong Kong."

The Trump administration has already moved to deport a number of foreign students, while revoking thousands of visas for others. Many of these actions have been blocked by the courts.

It has also frozen hundreds of millions of dollars in funding for universities. The president sees some of America's most elite institutions, such as Harvard, as too liberal and accuses them of failing to combat antisemitism on campus.

Many US universities rely on foreign students for a significant chunk of their funding - as those scholars often pay higher tuition fees.
