If the West banned Chinese students 30 years ago, this would be very difficult for China. But now it does not matter. China has enough research facilities, their best universities are on par and much better than western universities. China has taken the lead in many fields such as electronics, mechanics, artificial intelligence, uav, 5G, supercomputer ...
China should worry about foreign spies wandering around their universities and research facilities.
China should order universities and high-tech companies to ban white (german, australia, france, us, poland, new zealand ....)
Idiotic. On the contrary, China needs to expand its English language standards and import highly skilled labor like the US does.
