China's top Internet security official told Reuters that he has "mountains of data" pointing to extensive US hacking aimed at China. However, Huang Chengqing told them that it would be irresponsible to blame Washington for such attacks. Cyber security is a major concern for the U.S. government and is expected to be at the top of the agenda when President Barack Obama meets with Chinese President Xi Jinping in California on later this week.
Huang said that he had mountains of data, if we wanted to accuse the US, but it's not helpful in solving the problem. Huang runs the National Computer Network Emergency Response Technical Team/Coordination Centre of China, known as CNCERT.
