China Says Worried By New US Cyber Strategy

China's Defence Ministry expressed concern on Thursday at the Pentagon's updated cyber strategy that stresses the U.S. military's ability to retaliate with cyber weapons, saying this would only worsen tension over Internet security.The strategy presents a potentially far more muscular role for the U.S. military's cyber warriors than the Pentagon was willing to acknowledge in its last strategy rollouts in 2011 and singles out threats from Russia, China, Iran and North Korea.
