China leaves widow Nobel laureate Liu

China has let the widow of the late Nobel laureate and activist Liu Xiaobo.

Dissident Liu Xiaobo, who received the Nobel Peace Prize in 2010, died last year from the effects of liver cancer. He was awarded the prize while he was serving a prison sentence.

Liu was sentenced to eleven years in prison in 2009 for 'inciting to overthrow the state'. The former professor of literature was one of the driving forces behind Charta 08, a document signed by hundreds of Chinese people and calling on the communist government to reform.
