Internet Filtering in China in 2004-2005: A Country Study - The OpenNet Initiative tested China’s Internet filtering of web content, blog postings, and e-mail correspondences. Our testing found efforts to prevent access to a wide range of sensitive materials, from pornography to religious material to political dissent. Unlike the filtering systems in many other countries, China’s filtering regime appears to be carried out at various control points and also to be changing over time. China operates the most extensive, technologically sophisticated, and broad-reaching system of Internet filtering in the world. China’s intricate technical filtering regime is buttressed by an equally complex series of laws and regulations that control the access to and publication of material online. However, ONI found that most major American media sites, such as CNN, MSNBC, and ABC, are generally available in China (though the BBC remains blocked). Moreover, most sites we tested in our global list’s human rights and anonymizer categories are accessible as well. This has been added to International Trade Resources 2005 Internet MiniGuide.
