From The Times:
Hopes that the Olympic Games would usher in a relaxed approach to the internet had already been hit hard when the “Great Firewall of China” — the blocking of websites deemed subversive — was reimposed not long after foreign reporters left the country.
The temporary lifting of the firewall applied to only a few sites and Chinese citizens experienced few changes.
According to the latest rules, by mid-December all internet cafés in the main 14 city districts must install cameras to record the identities of their web surfers, who must by law be 18 or over. There are more than 250 million internet users in China, approximately ten times more than there were in 2000.
