Asked why the references about Liu were removed, Chinese Foreign Ministry spokesman Geng Shuang said that the ministry has the right to decide about the content of the transcripts.
"I answered more than 10 questions on the subject yesterday. When you are covering the press conference did you write the every word I said in your report. We have the right to decide which kind of content can go online," Geng said.
He was sentenced to 11 years in jail for his strident opposition to the one party rule of the Communist Party of China. Liu served eight years in jail before he was diagnosed with cancer.
He was awarded the 2010 Nobel Peace Prize while in jail and was represented by an empty chair at the ceremony in Oslo.
