An expert government panel on ending Japan's self-imposed ban on exercising the right to collective self-defense will discuss the country's response to cyberattacks, a government source said.

Collective self-defense is the notion of a nation aiding an ally that comes under attack. In this context, the panel will examine whether Japan should exercise the right and help defend another country whose computer systems are being targeted by an outside attack, the source said Monday.

It will also consider how Japan will deal with progress in space development, according to the source. Japan and the United States have cooperated on space security issues in view of China's expansion in this realm.
