Chinese artist Ai Weiwei arrested in latest government crackdown

"Ai is the most high-profile activist to have been detained in a government crackdown in which dozens of bloggers, human rights lawyers and writers have been swept up.

The arrests seem related to the government’s concern that activists in China want to launch a “jasmine revolution” similar to the popular uprisings roiling autocratic governments in the Middle East and North Africa." See the Washington Post
