And sentenced to five years. Xinhua reports:
According to the verdict, Ching Cheong is also deprived of political rights for one year and personal property worth 300,000 yuan (about US$37,500) has been confiscated.

"The penalty is a mitigated one considering that after Ching Cheong was detained, he voluntarily confessed to more espionage activities than those the state security departments had known about. He also gave up his notebook computer, which contained evidence of espionage, to the authorities," according to a document released by the court.
Xinhua has more details. It actually sounds like he got off relatively lightly, although one must always be suspicious of those voluntary confessions.
