Tencent, China’s largest Internet portal mostly known to us for its hugely popular instant messenger product QQ, published an updated report on the user numbers of its social networking service QZone last week. The report was only available in Chinese, but the folks over at Web2Asia were kind enough to translate it.

And if the self-reported numbers are not too much of an exaggeration, they’re nothing short of mind-blowing.

Even taken with a healthy grain of salt, the stats Tencent are presenting deserve a mention: the report claims more than 200 million people were using QZone as of January 31, 2009, surpassing international players like Facebook (which recently announced 175 million registered users) and MySpace.

For the sake of comparison, we took a look at the worldwide comScore stats for the aforementioned social networking services, but they only give you an overview of visitor numbers for QQ.com instead of QZone separately (which has its own subdomain). To be frank, we don’t even know if the comparison flies because we’re not sure where QQ the communication (IM) service ends and where QZone the social network begins.
