Chinese translations of President Barack Obama's inauguration speech posted Wednesday on popular online portals were missing his references to communism and dissent. The comments by the newly installed US president veered into potentially sensitive territory for China's ruling Communist Party, which maintains a tight grip over the Internet and the entirely state-run media. At one point, Obama said earlier generations "faced down communism and fascism not just with missiles and tanks, but with sturdy alliances and enduring convictions." He later addressed "those who cling to power through corruption and deceit and the silencing of dissent - know that you are on the wrong side of history." There was no immediate comment from the Web portals. Sina asked for an e-mailed request for comment and phones rang unanswered at Sohu. A woman in the Netease public relations department said the portal may have run a version taken from another site, and could not be reached again for further comment.
