It's surprising how few Chinese people study in America. With a population 1/14th of America, Australia has 150,000 Chinese students.<p>The US entry refusals should be familiar fare to Chinese citizens though, as their Govt employs stochastic enforcement all the time, including for censorship and as part of trade disputes.<p>It sucks for the individuals, but this really isn't about them, it's about the CCP and it's ongoing campaign of industrial espionage and global surveillance.<p>It is likely a number of 'students' were also part of the diaspora surveillance network, routinely reporting back about the behaviour of overseas Chinese citizens and especially minorities.
