Has it become harder for Chinese students to be accepted into graduate programs in the US? There've been ominous news articles recently about the prospects of Chinese students (here meaning students from the People's Republic of China, as opposed to ethnic Chinese students from other countries such as Singapore) in the US, e.g.

US blocking visas of some Chinese graduate students and researchers: DHS
Chinese grad students at US universities may soon be expelled

I am wondering how things are on the ground. I'm also interested in whether fewer Chinese students are applying to US graduate programs, if available. I know some parents are worried, but I don't know if that has translated into fewer applications.
Edit: rephrased in concrete terms, are US universities now taking the applicant's country of origin into account in graduate admissions?
US universities have always taken country of origin into account during admissions. I don't think there will be a major difference on the University side for admissions moving forward.
The visa situation is something else though. DHS is sitting on J1s, won't process H1Bs at all, but is still approving F1s and OPTs. This is likely to have a substantial chilling effect as it makes it much harder to do post completion training in the US.
I'm not sure they're going after china more than any other country - had a Singapore national just say forget it and walk away from a job offer over visa issues.
