China and Cyberwarfare: Public and Private

China's daily assault on US computers has resulted in "the greatest transfer of wealth in history." Not to mention military secrets and systems controlling gas pipelines. That's according to General Keith Alexander, who heads the US Cyber Command and the National Security Agency. China's widespread computer hacking includes corporate espionage, but the government denies the charge. In response, it brings up reports that the US disabled Iran's nuclear program with the infamous Stuxnet virus. Still, it has agreed to ease tensions with a regular schedule of bilateral meetings. The subject is also on the agenda for Friday's summit in Rancho Mirage, California, between President Obama and his Chinese counterpart, Xi Jinping.
