In the months before Defense Secretary Chuck Hagel’s arrival in Beijing on Monday, the Obama administration quietly held an extraordinary briefing for the Chinese military leadership on a subject officials have rarely discussed in public: the Pentagon’s emerging doctrine for defending against cyberattacks against the United States — and for using its cybertechnology against adversaries, including the Chinese.The idea was to allay Chinese concerns about plans to more than triple the number of American cyberwarriors to 6,000 by the end of 2016, a force that will include new teams the Pentagon plans to deploy to each military combatant command around the world. But the hope was to prompt the Chinese to give Washington a similar briefing about the many People’s Liberation Army units that are believed to be behind the escalating attacks on American corporations and government networks.
