Would the government ban:

- A Taiwanese student

- A Chinese student who grew up in America?

- A Chinese student who grew up in Canada?

- A Chinese student from a Chinese family that immigrated to Mexico?

No? The ethnicities and race are similar for all the above cases. And I don’t think anyone doubts Canada would them in. Showing - race has nothing to do with this equation.

Also, in many ways, it is possibly a mercy to the Chinese student himself; because then he won’t be put in a situation where the Chinese government puts his family (quite literally) at gunpoint.
