In Australian universities, Chinese students and Chinese professors kowtow to the long tentacles of China. So do the universities themselves.

Perhaps a computer system can be designed to enable students from China to participate pseudonymously in courses and seminars, for their protection.

However, I don't see what could possibly be done to make professors from China safe from Chinese repression.

I think that, in fields such as history and modern literature, in which honest evaluations of Chinese policies is crucial for teaching. Universities should not hire professors who would be inhibited by China's repression. I don't despise people who would be inhibited by that monster. I can understand it. But if they are inhibited that way, they can't be good professors, so the university must hire someone else.

As for how to prevent the university from kowtowing, perhaps it would be adequate to limit the number of students from China that can enroll in any one university, any one department, any one lab, etc. Limiting the amount of funds that come from China might limit China's influence.

These measures will be painful, but that pain must be suffered for the sake of the university's integrity.
