Searches for 'bitcoin' are being blocked in China on Google

[Christlove]

I can get a set of search links but if I click any of them I get a timed out page. I can only continue if I use an international VPN (I'm in Shanghai).
Bizarrely the Chinese for bitcoin (比特币）seems to create no problems and is actively being traded on taobao and on the Chinese exchanges.
