OTTAWA - Despite recent reports that the Chinese military is hacking Canadian computer systems, Prime Minister Stephen Harper won't say whether he'll raise the issue with the Chinese government.

"We are certainly aware of these kinds of security threats and risks that exist," said Harper while in Saskatoon. "We have professionals who constantly evaluate them and work with partners on addressing them, but beyond that, as I think you know, I never comment publicly on the specifics of national security matters."

Harper's answer is similar to what the Liberal government said in 2005, when he asked whether the Grits had raised espionage concerns with Beijing following reports of thousands of Chinese spies in Canada.
