China and Tibet: how to manage the media

China has responded to universal coverage of unrest in Tibet with an attempt to restrict access to the Internet. An expert in ‘filtering’ the Internet in Iran told me this morning that the Chinese are better at this because they built their Internet systems, while the Iranians attempted to control a system that was already in place. He says that neither work perfectly because they tend to censor using keywords. And anyway, there is always a minority of geeks who can find a way around the filters.
