China's Great Firewall, also known as the Golden Firewall, is monitored by between 30,000 and 50,000 'cyber police'. It is enabled by companies such as Yahoo!, Microsoft, Google, Sohu and Baidu.

"The internet is the new frontier in human rights," says China Campaign Coordinator Sophie Peer.

In its bid for the 2008 Beijing Olympic Games, China promised there would be 'free and unrestricted media access', but bloggers continue to be jailed, websites shut down and certain webpages remain censored.

On Wednesday 30 April, Amnesty International created a giant wall in Melbourne’s Federation Square. The wall will go on to tour around Australia for the next 90 days, visiting every capital city and many regional centres.

People can tear down and sign one of the 25,000 action cards, representing opposition to internet censorship and support for freedom of expression. These will then be directed to one of five technology companies.

"We are deeply concerned about the involvement of state run and global internet companies in government censorship in China. They should disclose the policies, laws and online practices which may result in user’s details being provided to authorities."

"We are calling on all internet service providers operating in China to publicly support the Universal Declaration of Human Rights, including the right to freedom of expression and the right to privacy."

This action is part of a global week of action by Amnesty International, to raise awareness about human rights violations in China.
