G7 Declaration on Responsible States Behavior in Cyberspace:
The G7 countries recognize the urgent need for international cooperation to promote security and stability in cyberspace, and commit to promoting a strategic framework for conflict prevention and cooperation.
They reaffirm that international law, including the UN Charter, applies to state behavior in cyberspace, and that the same human rights that people have offline must also be protected online.
The declaration notes that states have a responsibility to refrain from the threat or use of force against other states, and that international law provides a framework for responding to wrongful acts, including malicious cyber activities.
The G7 countries support the development of voluntary, non-binding norms of responsible state behavior in cyberspace, and call on states to publicly explain their views on how international law applies to their activities in cyberspace.
They also support confidence-building measures, including communication channels for crisis management, and the promotion of cooperation to increase stability and security in the use of ICTs.
The declaration articulates several voluntary, non-binding norms of state behavior, including cooperation to increase stability and security, consideration of all relevant information in case of ICT incidents, and not knowingly allowing territory to be used for internationally wrongful acts using ICTs.
