China clamping down on use of VPNs to evade Great Firewall


China is tightening control over foreign companies' internet use in a move some worry might disrupt their operations or jeopardize trade secrets as part of a crackdown on technology that allows web surfers to evade Beijing's online censorship.


In a letter to corporate customers seen by The Associated Press, the biggest Chinese internet service provider says virtual private networks, which create encrypted links between computers and can be used to see sites blocked by Beijing's web filters, will be permitted only to connect to a company's headquarters abroad. The letter from state-owned China Telecom Ltd. says VPN users are barred from linking to other sites outside China, a change that might block access to news, social media or business services that are obscured by its "Great Firewall."
