BEIJING has issued an internal circular asking officials and state businessmen to raise their guard against 'new Harry Wus'.
Yesterday, Chinese sources said the document was jointly issued by the Ministry of State Security and the State Bureau of Secrets.
The circular, which was disseminated to mid-ranking cadres or above, pointed out that 'hostile foreign forces' had stepped up their campaign of infiltration.
It said that one form of infiltration was to steal state secrets, which included party documents as well as classified military and commercial information.
'Officials and state businessmen of all levels must heighten their vigilance against foreign spies, their Chinese agents and other collaborators,' the circular reportedly said.
It made a brief reference to Harry Wu Hongda, the Chinese-American human rights activist who is under detention for alleged espionage.
