Peacekeeping and crisis management: a brief assessment of EU-UN cooperation

Peacekeeping, crisis management, EU-UN cooperation


The present short paper aims to add to the debate on the future of peacekeeping and crisis management in the current context of international relations. Starting from the premise that cooperation between the European Union and the United Nations (UN) for peace and security is a significant source of synergies between both organisations, the paper highlights the way in which the Common Foreign and Security Policy (CFSP) and the Common Security and Defence Policy (CSDP) were built, summarising the applicable legal regime, especially following the entry into force of the Lisbon Treaty. By providing a review of the legal background to EU crisis management and assessing the EU’s added value for UN-led efforts, the paper concludes that the Lisbon Treaty provisions provide the EU with the instruments necessary to assume a significant role in peacekeeping and crisis management. Although the EU’s natural partner in the field of peacekeeping and crisis management is the UN, there is growing uncertainty regarding the strength of the ties between both organisations as multilateralism traverses a crisis seemingly unlike others in the past.
