U.S. Secretary of State Marco Rubio announced on Wednesday the United States will start "aggressively" revoking visas of Chinese students, including those with connections to the Chinese Communist Party or studying in critical fields.

If applied to a broad segment of the hundreds of thousands of Chinese university students in the United States, the move could disrupt a major source of income for American schools and a crucial pipeline of talent for U.S. technology companies.

U.S. President Donald Trump's administration has sought to ramp up deportations and revoke student visas as part of wide-ranging efforts to fulfill its hard-line immigration agenda.
