After the collapse of bipolar system in the world, different views and theories expressed by the scholars and thinkers about the future of the world and international system. One of them is the theory of “ The Clash of Civilizations” which was propounded in 1993 by the Samuel Huntington, the director of J.M.Olin Institute for Strategic Studies in Harvard Uni-versity. This theory caused some anxieties in the world. In reaction to this theory, Mohammad Khatami, president of the Islamic Republic of Iran, proposed “Dialogue Among Civilizations” as a paradigm in the international relations which was accepted by the 53rd General Assembly of the United Nations on 3 September 1998 and approved a resolution for the purpose of promoting dialogue among cultures and civiliza-tions, and called the year 2001 as “the Year of Dialogue Among Civilizations”. This article based on both mentioned theories, refers to the role of dialogue approach in creation of peaceful relations between nations and states.
