BEIJING, June 25 -- Cyber security is the most important issue that China has to address in developing its new media, according to a report released Wednesday by the Chinese Academy of Social Sciences.

After the whistleblowing of former U.S. National Security Agency (NSA) contractor Edward Snowden, the think tank believes that cyber security is relevant to a country's political and cultural safety, more than just information security.

The United States is the world's sole power to adopt an offensive strategy in the cyber world, while China and Russia can only resort to a defensive strategy, meaning the defense of their cyber space will become a strategic priority, according to the report.

The think tank advised Chinese authorities to raise their capacities in self-defense and formulate an effective defensive strategy.
