Hongkongers are among hundreds of thousands of people who have signed a global petition demanding Beijing release Liu Xiaobo - the only Nobel peace laureate in jail and the world's most prominent political prisoner.
2010 Nobel Peace Prize laureate. Liu Xiaobo is a writer, professor, and political dissident. In 2009, Liu was sentenced to 11 years for inciting subversion because of his involvement in writing Charter 08, a petition advocating political reform in China. Liu was awarded the 2010 Nobel Peace Prize for “his long and non-violent struggle for fundamental human rights in China.”
