Authorities blocked reporting of unrest occurring around the world, from Inner Mongolia to the Occupy movement. More than half of the 27 journalists imprisoned on December 1 were from Tibet and Xinjiang, reflecting crackdowns after earlier unrest in minority regions. After online calls for Arab Spring-style demonstrations, dubbed the Jasmine revolution, CPJ documented the worst harassment of foreign journalists since the 2008 Olympics, including beatings and threats. Police detained dissidents--including outspoken artist Ai Weiwei--and writers they feared could galvanize protests, often without due process, and kept them under surveillance after release. Draft revisions to the criminal code would allow alleged antistate activists to be held in secret locations from 2012. Officials obstructed reporting on public health and food safety issues, among other investigations. President Hu Jintao’s U.S. visit and two bilateral dialogues, one on human rights, made little headway on press freedom, but domestic activists successfully challenged censorship using digital tools, especially microblogs.
