Secretary of State Hillary Clinton on Thursday called for an unfettered worldwide Internet and urged global condemnation of those who conduct cyber attacks, as China sought to contain tension with the United States over the hacking and censorship of Google... Countries that built electronic barriers to parts of the Internet or filtered search engine results contravened the U.N.'s Universal Declaration on Human Rights, which guarantees freedom of information, she said... She urged U.S. private firms to look beyond profits to play a "proactive role in challenging foreign governments' demands for censorship and surveillance."
