The ashes of the late Chinese democracy advocate and literary critic Liu Xiaobo were buried at sea near Dalian city in northeast China on July 15, two days after he died of liver failure.
In interviews with Hong Kong television outlets, Liu’s brother, Liu Xiaoguang, expressed “great thanks and appreciation to the Chinese Communist party” for Liu Xiaobo’s cancer treatment and funeral arrangement.
But Liu Xiaobo's supporters believe that the he was buried at sea to prevent people in China from paying tribute to the Nobel laureate at his grave.
In fact, most of Liu’s friends could not attend the funeral. While his wife, Liu Xia, had appeared on photos of his funeral and sea burial, she has lost touch with her friends.
Liu Xiaobo had been sentenced to 11 years in prison in 2009 for “inciting subversion of state power” for his involvement in Charter 08, a manifesto that called for democratic reforms in China. He won the Nobel Peace Prize in 2010 for his human rights work.
On social media, including Weibo and WeChat, researchers documented a significant increase in censorship after Liu Xiaobo’s death. According to Toronto-based digital rights research group Citizen Lab, discussions of Liu and his work are no longer tolerated.
On Facebook, Hong Kong academic and Citizen Lab researcher Lokman Tsui summarized the group's findings:
