We are pushing the (United Nations) Secretariat through the secretary-general to do something outside his office, but we are also looking at options outside the United Nations,” she added These may be conducted under the auspices of the Group of Seven, think tanks or research institutions.

Thomas-Greenfield said the United States and its partners, which are pushing for a new surveillance regime, may consider having several teams replace the work of existing groups.
