There is an American, a European, and a Chinese...
Human rights in China are in a mess. At least they are from a Western perspective. An Italian journalist, who is presently attending a Master in Journalism at Università di Padova is closely following the developments. Matteo Mohorovicich keeps a very interesting blog about the subject.
Citizenlab has something more on Western companies selling technologies that the Chinese government uses to block their people freedom of information and expression. The Us company SecureComputing, Citizenlab also says, is selling filtering technologies used by authoritarian regimes in Saudi Arabia, United Arab Emirates, Tunisia, and Iran.
Cisco, whose technology is used in China to block the people that want to freely use the Internet, has answered me that they just sell machines and that they don't adjust them to the special use that the Chinese government makes of them. The same could be probably said about Sun helping the Chinese in implementing Linux in their country: the Chinese, it seems, use the open source solution to introduce troyan horses meant to control the use of the Internet. We all know about Google being filtered for the same purpose.
The Us don't want Europe to sell weapons to China. Should we ask the Us not to sell any technologies that can be used to damage human rights in China?
Any problem with China is big and tricky. This is bigger and trickyer than most.
