If you look at EU court decisions concerning privacy, you see that it mostly concerns European companies and government bodies (e.g. people storing their fingerprints being stored for passport applications). Those cases just don't get as much exposure in the US:

Another factor here may be that EU companies generally stick more to privacy rules, because it is easier to get sued directly by their citizens. E.g. in Germany many institutions and companies are paranoid when it comes to privacy and go out of their way to avoid lawsuits.
To use your example, US has targeted companies from IP-protection-weak countries. Was it directly targeting China? I'd say not necessarily.
It is like the Microsoft anti competition case would not take place until we find some small non US OS vendor to punish first so the Americans won't get upset.
