Liu Xiaobo was uninvolved with any manifesto.
In January 1991, 19 months after his arrest, Liu Xiaobo was convicted of "counterrevolutionary propaganda and incitement" but he was exempted from criminal punishment due to his "major meritorious action" for preventing what could have been a bloody confrontation in Tiananmen Square
 On 8 December 2008, Liu was detained due to his participation with the Charter 08 manifesto
