The logical counter-response would be to encourage the sort of unrest present in the "Jasmine Revolution". This would present China with the same sort of dilemma...they might suspect (or even know) that we were stirring up trouble, but would probably be reluctant to go to war over it.
Who said anything about helping them? I was responding to a comment that suggested we had no useful counter-strategy to hacking, since it's difficult to respond to a cyber attack via conventional means. They know this, which is why it's relatively safe for them to engage in targeted hacking of US targets.
China is vulnerable to social unrest, and stirring up that social unrest puts them in a similarly difficult position...it's not something that they'd likely be willing to go to war over, but causes them great inconvenience. Developing/distributing vpn or other software that would bypass the great firewall would be useful here.
