Hard to say - this could be a way to force universities to fully open as well; most universities with heavy international population would want this to happen to their paying students.
As has become the norm, this punch will boomerang back and have the opposite effect. China's brain drain [1] further reduces and the engineers who would've built companies here will do so in China now.
I mean, China just has more people. If you look at per capita numbers, China has barely 2x the number of enrolled students as France (and the US is not really a target market for french students).
