عنوان مقاله [English]
The presence of non-state actors, such as the European Union, in international relations, has revolutionized the nature of multilateralism. This development has led to the emergence of a new type of multilateralism called multilateralism2.0 or modern multilateralism. This concept is taken from Web 2.0 and its main features are the diversity of multilateral organizations, the growing importance of non-governmental actors such as regional organizations, multipolar order, and open system. The authors, therefore, seek to introduce the concept of multilateralism as a metaphor for understanding the role of the European Union in the evolving context of international relations. This article seeks to answer this question: how the EU has been at the forefront of this kind of multilateralism. The authors argue that entry into multilateralism2.0 requires the role of regional actors. The European Union, as a regional player with membership in the United Nations and the G8, has been able to lead the way in modern multilateralism. In fact, in order to redefine its role in the context of the international system, the European Union has sought to adapt to these developments. In this article, the authors tried to evaluate the question and hypothesis of the article in a descriptive-analytical manner.
