Authorities insist Liu is receiving the best treatment possible, while keeping the dissident under strict surveillance, refusing to allow him to leave the country to seek treatment overseas as his family wishes.
The Shenyang judicial authorities have been steadily releasing more details on Liu's condition and treatment, revealing that his wife has been staying with him at the hospital and that traditional Chinese medicine (TCM) practitioners have been invited into the medical team at the family's request.
Wu on Thursday shared on social media an undated photo of a visibly emaciated Liu, in blue-and-white-striped hospital pajamas, embracing his wife Liu Xia, who gazed up at his expressionless face.
"They will join the medical team composed of renowned Chinese oncologists to treat Liu", the statement said.
Liu was sentenced to 11 years in prison in 2009 for "subversion" after drafting Charter '08, a manifesto calling for democratic reforms in China. He was recently moved from jail to a hospital to be treated for late-stage liver cancer.
Beijing has come under fire from human rights groups over its treatment of Liu and for waiting until he became so ill to take him out of prison, but authorities insist he has been afforded top medical care from renowned doctors.
"We feel this is deeply tragic and realise that Liu Xiaobo has few days left and fear he is near death", says the letter signed by 44 scholars, writers and activists. And this week just happens to be when the G20 summit is taking place in Germany, where China plans to continue portraying itself as the world's new champion of free trade and openness at a time of perceived USA retreat.
But as Amnesty's secretary general Salil Shetty said, "Time is running out for Liu Xiaobo"-and perhaps much faster than people had thought".
The concession by China is seen by some as an attempt to improve its image on human rights as Chinese President Xi Jinping attends a G-20 Summit in Germany this weekend.
At a press conference, Foreign Ministry spokesperson Geng Shuang said the government "hopes that other countries will respect China's sovereignty... a country under the rule of law, where everyone is equal in front of the law".
Activist and dissident Hu Jia on Thursday accused China's Communist Party of denying Liu his freedom, which he said would be the best possible treatment. He was a key leader in the Tiananmen Square protests in 1989 and won the Nobel Peace Prize in 2010. "The Chinese government wants him to die in China".
"It is not too late for the authorities to end this cruel farce", it said in a statement, adding that the invitation to foreign experts appeared to be "in part an attempt to limit global criticism".
