I can't read Swiss... but the comments on Reddit seem to show that this isn't as cut and dry as the title makes it sound. Quoting /u/hamsterman20:
> "First of all, he was going to a chinese university with a chinese scholarship.
> He left the swiss university because of some weird technicalities while attending the Chinese university.
> He posted political messages against china and 1 picture depicting a chinese with yellow skin and slit eyes.
> Im not surprised he was kicked out of the chinese university and that the supervisor wanted to distance themselves. Though I wish they would stand up against China, its hard when your career depends on it.
> His swiss university refused to take them back. Don't know why. Technicalities I guess."
I'm sure there's still more to the story, and that it obviously isn't entirely the student's fault, but it isn't like a Swiss Student randomly tweeted about the CCP and got kicked out.
