Long before Google launched Google.cn, it launched the Chinese localized version of Google.com.
And this site is alive and well and hosted outside of China’s great firewall.
Just change your browser’s language preference to Chinese and you’ll see it the next time you visit Google.
And had China not continually blocked this site from Chinese citizens years ago, perhaps Google would not have compromised so to enter the market.
But it did. Its services got blocked anyway. And Baidu is still number one.
Here’s a good article that posits that Google’s Korea strategy is what led to what is happening right now with China.
