WSJ: China Finds New Ways to Restrict Access to the Internet (subscription required)
The Wall Street Journal has published an article discussing various ways Chinese authorities censor the Internet. Several of the techniques, such as blocking Google's cache and filtering key words on Google searches, have been known for some time (see CECC 2003 Annual Report, p. 39). Other techniques discussed in the WSJ article include a list of banned words and phrases such as "freedom" and "democracy" that the Chinese company Tencent embeds in desktop software to filter messaging among PCs and cellphones. A complete list of the words is available from the China Digital News.
