Both google.com and google.com.cn are blocked, along with all other country specific Google domains.

Thanks for the clarification. I was going by this wikipedia page. https://en.wikipedia.org/wiki/Websites_blocked_in_mainland_C...

So google.com, which does detract from my point.

It's okay. I think your points are still very beneficial to have. IMO native companies always have advantage as they usually have better understanding about the culture, user preference, and government. Portal is a big thing in the Eastern Asian countries like China and Japan so for a long time Yahoo and MSN search used to be leading the game until, of course, more Internet search engines come online.
