The Institute of International Affairs works closely with its sister institutes in the Nordic countries, the Danish Institute for International Studies (DIIS), the Swedish Institute of International Affairs (UI), the Norwegian Institute of International Affairs (NUPI) and the Finnish Institute of International Affairs (FIIA).

The Danish Institute for International Studies (DIIS) is an independent public research institution for international studies. DIIS conducts and communicates multidisciplinary research and aims to be agenda-setting in research, policy and public debate. DIIS researches foreign, security and development policy. The institute carries out basic research, policy analysis and commissioned research. DIIS features high in the international rankings of the world’s leading research institutes and think tanks, and the Institute publishes its research in both recognised academic journals and popular science formats.

The Swedish Institute of International Affairs (UI) is an independent institute and a platform for research and information on international relations and foreign policy. The institute has extensive experience in monitoring and analyzing the world, and is a trusted source of analysis of international relations, foreign affairs and current events. UI strives to create an open conversation about a complex world – a conversation founded in quality research and accessible analysis.

The Norwegian Institute of International Affairs (NUPI) is a leading centre for research on international issues in areas of particular relevance to Norwegian foreign policy. NUPI communicates research-based insights to the Norwegian public as well as to wider international audiences. NUPI has three main pillars of research and expertise: security and risk, growth and development, and international order and governance. The Security and Risk pillar covers traditional security and defence policy and peace operations, as well as other aspects of risk in Norwegian foreign policy related to greater investment, travel and presence abroad. Growth and development focuses on the emerging powers, international economics and developmental issues. Order and governance covers the multilateral system, regional organizations and how diplomacy as an institution works and evolves.

The Finnish Institute of International Affairs (FIIA) is a research institute whose mission is to produce high quality, topical information on international relations and the EU. The Institute realizes its aims by conducting research as well as by organizing domestic and international seminars and publishing reports on its research and current international issues.
