Since the end of the Cold War, international co-operation has been central to Denmark in terms of foreign, security and defence policy.
Denmark joined the European cooperation on security and defence on 1 July 2022 with the abolition of the Danish EU defence opt-out. As a result, Denmark can now choose to contribute to EU’s military missions and operations as well as apply for participation in the Permanent Structured Cooperation (PESCO) in the area of security and defence and the European Defence Agency (EDA).
Denmark has participated in UN peacekeeping missions since the establishment of the first mission in 1948.
The Nordic countries have a long tradition for working closely together. This includes within the area of defence and security policy. The Nordic Defence Cooperation (NORDEFCO) encompasses all of the Nordic countries, i.e. Denmark, Finland, Iceland, Norway and Sweden.
International emergency preparedness cooperation primarily includes civil protection, but also health preparedness, marine environmental preparedness, etc.
