Tbh, a lot of EU protectionism vs. US tech seems not to keep the competition out. In fact, with the amount of free press US startups get and the size of their coffers, they can simply roll over the local competition in EU markets most of the time.
What it's terribly good at is adding burdens that the US giants don't face early on, slowing down the early growth between 28 fragmented markets. I don't know specifically about how China works, but the question is proving product-market fit, and for that, you need a lot of users fast.
In the EU, it's a different battle country to country as the media environment, the markets, the regulation etc. are all fractured.
