There were 298m internet users in China in December 2008

"China's Internet population swelled to nearly 300 million by the end of last year, with the penetration surpassing the global average for the first time, according to a quasi-government organization.
The number of Internet users in the country reached 298 million by the end of 2008, representing a 41.9 percent growth compared to the previous year, said a report by the China Internet Network Information Center (CNNIC).
More than 90 percent of the Internet users surf the Web via broadband access, CNNIC said. The penetration stood at 22.6 percent by Dec 31, compared to a global average of 21.9 percent.
That represented a major leap forward for China since the country overtook the United States as the world’s largest Internet population in June, 2008, CNNIC said."
