Chinese labour activist Liu Shaoming is the latest victim of the authorities’ relentless assault on human rights, Amnesty International said, after he was sentenced to four and a half years in jail for publishing his story of the 1989 Tiananmen crackdown. On Friday, a court in Guangzhou found Liu Shaoming guilty of “inciting subversion of state power”. He has already spent more than two years in detention, after he was taken away by police on 30 May 2015. His detention occurred five days after he published an article on US-website Boxun.com reflecting on his involvement in China’s 1989 pro-democracy movement. “This is a most callous and unjust verdict against Liu Shaoming. He is a prisoner of conscience and must be immediately and unconditionally released. All that Liu Shaoming is guilty of is the legitimate exercise of his freedom of expression,” said William Nee, China Researcher at Amnesty International.
