China takes the issue of cyber security seriously and resolutely opposes hacker attack in all forms. We have repeatedly said that cyber security is an international thorny issue and hacker attack is a common challenge facing the whole world. Technically, it is very difficult to trace the source and pinpoint relevant hacker. I am wondering how can relevant reports be so sure about it.

Given that cyber security is a common issue facing the international community, we need to sit down for clam and useful discussions and work out relevant rules to safeguard a peaceful, secure, open and cooperative cyber space. Groundless accusations do not help solve the issue.
