A veteran journalist who is one of the best-known intellectuals to have been imprisoned for supporting the 1989 Tiananmen pro-democracy protests has gone on trial in closed-door proceedings in Beijing on new accusations of leaking state secrets.
Gao Yu, 70, was detained for illegally obtaining a secret Communist Party document and providing it to a website for publication, according to previous state media reports.
Those reports did not identify the document, but it appeared to refer to reports outside the mainland last year about a high-level, internal circular seen as outlining the party's strategy of attacking Western democratic ideals and crushing dissent to protect its rule.
Gao previously was imprisoned on state secrets charges for more than a year after the 1989 crackdown.
