This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University London.This thesis addresses the gap in the literature of the Gulf Cooperation Council and its distinct relations with the European Union by identifying the obstacles preventing the development of GCC–EU interregionalism, in two case studies: energy security and economic cooperation in the Mediterranean. By bringing an empirical application of interregionalism to the study of GCC–EU relations, the thesis draws an original comparison that is based on a Hettne and Söderbaum typology of regionness (2000) to determine the GCC’s and the EU’s types, levels of actorness and the subsequent type of interregionalism resulting from the interaction between their kinds. The theoretical construct of the thesis underlines interregionalism as a tool for consolidating the organisations’ identities and actorness and increasing their capacities at exerting influence within the changing dynamics in the regional and global theatres. In addition, this thesis sheds light on the obstacles that impede the development of interregional cooperation and the mechanism to overcome them. As such, the thesis considers the dynamics instigating the renewed interest in deepening GCC–EU interregional relations; outlines the tools available at the GCC and the EU, and highlights the implications of the Arab Spring and GCC–Asia ties on GCC–EU relations. By avoiding benchmarking the EU as a model, the thesis purports that cooperation in energy security is ongoing and is opening avenues for promising partnerships in renewables, energy sustainability and efficiency. On the other hand, the divergence in the organisations’ levels of actorness, economic strategies and the unwillingness to assess policies are major hindrances against a successful partnership in the Mediterranean. Asymmetries in actorness, bilateralism, the American influence and the growing GCC–Asia ties do impact the development of the relations; albeit, they do not impede the multilateral framework from producing unintended outcomes in other areas of the relations.Saudi Arabian Ministry of Higher Educatio
