New regulations have been enforced in an area of central Beijing requiring bars, restaurants, hotels and bookstores to install web monitoring software. The software costs businesses around 20,000 RMB (£1,900) and provides public security officials the identities of those logging on to the wireless service of a restaurant, cafe or private school, while monitoring their online activity. Those who ignore the regulation face a fine of a similar sum and the possible revocation of their business license. It remains unclear how strictly the measures will be enforced, or whether they will extend beyond the Dongcheng district of Beijing.
