The "funny" thing is, our governments are probably doing very similar things (though still to a lesser degree, and secretly). A big difference is that China often doesn't have a sense of tact when it comes to not sounding dystopian, and happiliy uses phrases like "citizen score", "criminal elements" and "reeducation". Also Big-Character posters are still a thing [1], though slightly modernized.
Although, we are getting there. At O'Hare airport in Chicago I remember seeing a poster urging me to "be vigilant", which has a nice ring to it...
