Chatham House is a membership based policy institute which brings together people and organizations with an interest in international affairs. We provide our members with an independent forum which allows them to interact in an open and impartial environment with business leaders, academics, diplomats, the media, non-governmental organizations, policy-makers and researchers.

Our mission is to be a world-leading source of independent analysis, informed debate and influential ideas on how to build a prosperous and secure world for all. For five years running Chatham House has been ranked top non-US think tank in a comprehensive global survey.
