Online attacks originating from IP addresses and servers in other countries and regions have grown sharply, said a report by the National Computer Network Emergency Response Technical Team （CNCERT/CC）published on Tuesday.

The government is working with 91 foreign organizations, covering 51 countries, and has signed 12 international agreements on cyberprotection, one of the report's authors said.
