The most infamous country in the world for censoring what citizens can see online is China. China isn’t the lone country that censors access to information though; Tunisia and Uzbekistan both censor the internet, and Egypt has detained bloggers who disagree with the government before.

Secretary of State Hillary Clinton has denounced countries that use technology to prevent citizens from accessing information freely. Clinton delivered the speech on January 21 and outlined the five key freedoms of the internet age that will be used to help build U.S. policy.

Clinton's speech outlined the commitment of the U.S. to freedom of speech and worship online, the freedom to connect to the internet anywhere, and the freedom to live without fear of cyber attacks.

Clinton said, "Countries that restrict free access to information or violate the basic rights of Internet users risk walling themselves off from the progress of the next century. In the last year, we've seen a spike in threats to the free flow of information. China, Tunisia and Uzbekistan have stepped up their censorship of the Internet."

She continued saying, "[The internet] has already been a source of tremendous progress in China, and it is fabulous there are so many people in China now online." Clinton added, "The United States and China have different views on this issue. And we intend to address those differences candidly and consistently in the context of our positive, cooperative and comprehensive relationship."

The comments come after the U.S. asked China for an explanation for the cyber attacks against search giant Google and 30 other U.S. companies that were targeted in attacks that originated in China. Google has stated that it may consider leaving the Chinese market due to the attacks and the censorship of its search results required by the Chinese government.
