Differentiated Cooperation in the EU’s Foreign and Security Policy: Effectiveness, Accountability, Legitimacy
The International Spectator
Marco Siddi, Tyyne Karjalainen and Juha Jokela

An article titled “Differentiated Cooperation in the EU’s Foreign and Security Policy: Effectiveness, Accountability, Legitimacy” by FIIA Senior Research Fellow Marco Siddi, FIIA Research Fellow Tyyne Karjalainen and FIIA Programme Director Juha Jokela has been published in The International Spectator. The article argues that differentiated cooperation has had positive outcomes when it has adhered to common EU values and positions. When this has not been the case, differentiation has undermined EU foreign and security policy.

This article, as well as the Special Issue in which it is included, is one of the outputs of research conducted in the framework of the EU IDEA research project – Integration and Differentiation for Effectiveness and Accountability – which received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement no. 822622.
