I have a Xaiomi Android One phone and it only pings google servers, most activity is from Google Play Serives which many Android apps require to function, have never seen a Chinese server in the logs. It's probably a different story with the MIUI OS.

Sinkholing all requests the most concerning one Ive found is Google analytics running as root continually trying to dial out every few minutes. It doesn't give up and keeps retrying even after hours of failed requests. This is without any phone/internet usage.
