Chinese Authorities Arresting Critics

According to these reports in The New York Times, Chinese authorities are more or less systematically detaining critics, notably artists and writers. Prominence seems no longer to afford any protection, as the regime has detained even the very visible artist Ai Weiwei. (This helpful post at The New Yorker provides some context. This is not the first time he has had run-ins with the authorities - you can find a digest here at The Guardian.)
