What countries are banned from OKEX?

I'm curious about the restrictions on OKEX's services. Could you please elaborate on which countries are currently banned from accessing OKEX's platform? It would be great to understand the reasons behind these bans, if any, and whether there are any potential workarounds or alternatives for users in those countries. Additionally, I'm also interested in knowing if OKEX plans to expand its services to more countries in the future and what steps they're taking to ensure compliance with local regulations.
