Two men were sentenced to time in jail for dealing with an overseas spy agency and selling State secrets, the Hunan Province security bureau said on Monday.
One of them, surnamed Zhan, was a military veteran and had been working in the Hunan urban management bureau since 2004. Zhan publicly admitted he needed financial support.
Zhan was followed by a foreign spy agency in 2011 which provided him with a part-time job to collect government files and those of troops who served with him, the bureau said.
The bureau added Zhan stole more than 10 classified files including six intelligence files from the army and earned at least 10,000 yuan ($1,610). He was sentenced in December 2014.
Hunan security authorities said foreign spy agencies collected information by keeping in touch with the Chinese people through the Internet.
Another man surnamed Peng, a teacher and the chairman of a school's teachers' union, was found stealing classified documents from government departments, news website chinanews.com reported Monday.
Peng had also asked for secret files from government and Party organizations.
Peng, who was contacted by a spy agency through instant messenger Tencent QQ in October 2008, was paid over 60,000 yuan for sending more than 100 pieces of classified material to the agency.
The agency told Peng that they had business connections in China and needed information on Chinese policy and the economy, the Hunan authorities said.
Peng's behavior had a serious effect on China's national security interests and authorities arrested him in June 2014.
