Dr Nguyen Dan Que, a medical doctor, was arrested in 1990 and sentenced in 1991 to 20 years' imprisonment. He was a founding member of the Cao Trao Nhan Ban (High Tide of Humanism Movement), and wrote the organization's manifesto, which called for democratic change in Viet Nam. On the release from his first imprisonment he became a member of Amnesty International. When he was re-arrested in 1990, one of the charges against him was his membership in the organization. He had previously been detained without trial for 12 years between 1976 and 1988. "The release of Nguyen Dan Que is a cause for celebration," Amnesty International said.
