OpenAI does not allow users from China, including Hong Kong.

Hong Kong generally does not have a Great Firewall, so the only thing preventing Hong Kong users from using ChatGPT is Open AI's policy. They don't allow registration from Hong Kong phone numbers, from Hong Kong credit cards, etc.

I'd say it's been pretty deliberate.

Reason? Presumably in alignment with US government policies of trying to slow down China's development in AI, alongside with the chips bans etc etc.
