NSA security leader Adm. Michael Rogers warned that despite the new agreement between the U.S. and China to stop cyberespionage, the two countries need to do much more.
Rogers favors a broad-ranging economic accord with China that touches on broader issues of cybersecurity.
Rogers appeared in an open hearing of the Senate intelligence committee.
The new agreement signed last week between the U.S. and China focuses on cyberespionage, but Rogers said the two countries need to expand that to address theft of intellectual property as well.
"The greatest amount of activity is still criminal-based, but when I look at [it] from a national security perspective I would argue at the moment the nation-state represents the greater national security challenge," Rogers said.
Rogers supports a multilateral agreement on "norms" in the cyber arena that would curtail cyberespionage as well as theft of intellectual property.
