The article says nothing about English language skills. It says:
'University officials have described the unwritten policy as a prudent response to the current uncertainty facing Chinese and other foreign students when they apply for visas to study in the United States. “They are telling us that these foreign students may not show up if we offer them a position,” the faculty member says. “And that could jeopardize our research.”'
My wife teachers in universities in London, and the issue of Chinese students turning up with little or no English is real, often having paid for someone else to take the required English language tests for them. She has had students write their essays in Chinese and then just copied and pasted from Google Translate, generating utterly unintelligible dross. But that is definitively not the explanation here - this is all Chinese students, proficient in English or not.
