Patriot Act - Chinese Version

From a column in today's (12/30/2005) New York Times:

With more than 100 million users, the Internet is booming in China. The American Web giants Microsoft, Yahoo and Google have all grabbed a piece of the lucrative Chinese market - but only after agreeing to help the government censor speech on the Web.

In providing portals or search engines, all three companies are abiding by the government's censorship of certain ideas and keywords, like "Tiananmen massacre," "Taiwanese independence," "corruption" and "democracy."

Most foreign news sites are blocked. This year, Yahoo even supplied information that helped the government track and convict a political dissident who sent an e-mail message with forbidden thoughts from a Yahoo account; he was sentenced to 10 years in jail. [emphasis added]

Sounds like China's own version of the Patriot Act. Or, is it the other way around?
