I am a huge fan of the China Rises blog written by Tim Johnson, Beijing bureau chief for McClatchy Newspapers. Johnson has a great catch about how Chinese censors reacted to the following paragraph in Obama’s speech:

“Recall that earlier generations faced down communism and fascism not
just with missiles and tanks, but with sturdy alliances and enduring
convictions. To those who cling to power through corruption and deceit
and the silencing of dissent, know that you are on the wrong side of
history but that we will extend a hand if you are willing to unclench
your fist.”

There’s a YouTube clip of Chinese coverage that shows the censors in action. Reuters also has a report on the censorship.
