> there are more websites accessible from Hong Kong than from the EU.

After a quick search, I couldn't find a source that claims that any website is blocked in Hong Kong, and several that claim that no website is blocked.

The Internet connection is monitored, there's pressure and self-censorship, but there's no blocked access to websites. It's easy to be bigger than zero.

EDIT: The biggest collection of the websites I could find lists 1129 that are still blocking access to EU citizens, and 252 that stopped (presumably, once they've become GDPR compliant): https://data.verifiedjoseph.com/dataset/websites-not-availab...
