**Nobel Laureates Urge China to Release Imprisoned Peace Prize Winner**
More than 100 Nobel laureates from around the globe are urging China's incoming President Xi Jinping to free imprisoned Chinese dissident and Nobel Peace Prize winner Liu Xiaobo.
The group of 134 Nobel winners sent a letter to Xi Tuesday, asking him to "immediately and unconditionally release" Liu, who is serving an 11-year prison sentence for "inciting subversion." They also want his wife Liu Xia to be released from house arrest she was placed under after her husband won the award in 2010.
The group, which includes Archbishop Desmond Tutu and the Dalai Lama, said the release of Liu and his wife would be an "essential first step" toward embracing the fundamental rights of Chinese citizens. The Nobel laureates warned that no government can restrict freedom of thought and association without hindering its development.
Chinese authorities sentenced Liu Xiaobo to 11 years in prison in 2009 on subversion charges related to his co-authoring of "Charter 08," a manifesto calling for political reforms and greater rights in Communist-ruled China.
