The regional inter-parliamentary cooperation assembly, Euronest, has been described in the context of the Eastern Partnership (EaP) policy, yet not conceptually analysed. This article therefore aims to focus on the identification of the driving forces behind multilateral parliamentary cooperation in the EaP region. Following a literature review, three conceptual interpretations of the drivers of inter-parliamentary cooperation can be pointed out: institutionalization, socialization and parliamentary diplomacy. The research shows that all the three possible explanations play a role in driving the Euronest Parliamentary Assembly. Parliamentary diplomacy, including both formal and informal tracks, is concluded to play the leading role in the development of Euronest. Institutions, such as secretariats and political party families, have a lot of potential but are still in their infancy. Socialization is seen as a goal of Euronest, but with serious limitations.
