China makes no false claims about controlling all technology that enters the region. That’s why their rules are fairly simple to follow.
The EU on the other hand…
I guess the big difference is, China’s not afraid to say, “We don’t want Facebook.” The EU wants SO badly to say that, but they’d rather have Facebook and then fine them. The EU is focused more on the money. China didn’t want WhatsApp, so there’s WeChat. The EU lacks the ability to define a state sponsored solution, so they have to mold what exists into something they’d prefer.
