Xia Lin was sentenced today by the Beijing No. 2 Intermediate Court, nearly two years after being detained, lawyer Ding Xikui said.
"We've been striving to defend his innocence," Ding said. "Even one day in prison is too much."
There was no immediate comment from the court. Ding said Xia planned to file an appeal.
It came amid a string of recent cases and subversion trials demonstrating the Communist Party's determination to silence independent human rights activists and government critics. But the most those accused received was 7 ½ years.

By comparison, Nobel Peace Prize winner Liu Xiaobo, identified by the party as an existential threat to its rule, is serving an 11-year sentence for subversion.
Wang said president and party leader Xi Jinping has made clear that, despite its calls for strengthened rule of law, the party intends to use the legal system to enforce its uncontested rule. "Anyone who challenges this aspiration will not be tolerated."
Ding and advocacy group Network of Chinese Human Rights Defenders said the charges against Xia, who was born in 1970, related to money he borrowed from friends, who asserted they loaned it freely and had not brought legal complaints against him. He was accused of defaulting on that debt, but no convincing evidence was provided, they said.
