eMarketer reports that China internet users has reached the 100 million mark:

"In its "16th Statistical Survey Report on Internet Development in China," the agency put the total number of Internet users at 103 million as of July 2005. China is already the largest country in the Asia-Pacific region in terms of Internet users. The US is the only country with a larger online population. But with only 10% of the Chinese population online, the potential for Internet growth in China overshadows the US. "

Now, when they say 'Internet users', they actually mean Firewalled Internet users.
