Beijing officials have threatened to shut down cybercafes where punters are caught peering at porn. A statement has been issued laying down strict new guidelines in an attempt to wipe out "mischievous" use of the Web, The China Daily reported. The authorities said they planned to vet all cafes to judge who was worthy of running one. They warned owners about allowing "any activities that would damage state security, disturb public order and interfere with the public's rights and interests". Web naughties are seen as one of the most serious offences by communist China. "Internet cafes where customers are found viewing Internet pornography will be shut down permanently or temporarily," the paper said. This attempt to restrict freedom on the Net is the second in China this year. Last month, officials in Shanghai raided and claiming they posed a threat to state secrets. There are an estimated nine million Web users in China with potential access to information outside the control of the country's censorship machine. ® Related Stories China shuts down Internet cafes China orders Web sites to guard against security leaks Chinese dissident released from jail China eases crypto restrictions
