The phones that run the Google OS are approximately 100% manufactured in China, just like the phones that run the Apple OS.
1. Google benefits from Android, but ios is apple. Google has other games.
2. Google doesn't make most androids. China would have to ban any company from making hardware designed to run android, not just ban Google from operating in the country, which would affect a bunch of non-google (even non-us) companies at least as much as it would affect Google itself.
