Bar to STEM students stems from targeted policy flip of Washington

Reportedly, four Chinese students who travelled to the United States to study and participate in academic conferences suffered from the US side's unwarranted harassment, interrogation and repatriation. All of them have scientific and technical backgrounds.

The officers with US Customs and Border Protection repeatedly questioned them about their personal and family information, whether they are members of the Communist Party of China, and whether they have cooperated with the Chinese government.

This is just the latest politicized law enforcement move the US side has taken targeting Chinese students and researchers with backgrounds in science, technology, engineering and mathematics. Such discriminatory actions started a few years ago when the US defined China as its No 1 rival.
