London Heathrow has face-tracking gates. Entering the US has required fingerprints for many years, at least for me.

I can't imagine how an international traveller could in good faith single out China as having "total control" on these grounds in a way that is qualitatively different from Western countries.

U.S. airports do this too, but you can opt-out.

Some flights from Europe to US do this at the gate -- there's no opt-out. I remember flying AA from AMS and everybody had to get scanned before boarding (CBP agents were present).
