The Council of Councils (CoC) is a global think tank network initiated and established by CFR. It aims to connect leading foreign policy institutions from around the world in an open dialogue on issues of global governance and multilateral cooperation, pool the wisdom to address common threats, and sponsor innovative ideas for advice and solutions to the public policy debate and decision-making process of the member states. It is now made up of well-known think tanks from 24 countries, and its membership is roughly similar to that of the Group of 20 (G20). A full list of member institutions is available on CoC roster page.
