The US calling on the Chinese to stop cyber-espionage is ISIS telling Al-Qaeda to stop raping women.
I am sure the Chinese know this and are laughing at the arrogance of the US govt. The US govt are fools if they think china is just going to stop.
The thing to do would be build a better system to protect systems critical to national security. Rather than spending all the money bankrolling the biggest surveillance system in the history of the world.
