Since the changes in the international system resulting from the end of the Cold War and those arising from such global processes as economic globalization and information revolution the role and position of foreign policy in improving political, economic, cultural and security situation of countries have gained more importance. The present paper seeks to answer the question as to what has been the impact of global developments, resulting from changes in the international system and globalization, over the Iran’s foreign policy of Iran in the past two decades. This author is of the view that, pursuant to these developments, economic and cultural tools in furthering foreign policy goals have become more important and, despite the continued emphasis on the earlier principles and ideals of the Islamic Revolution, the country’s foreign policy discourse underwent changes, including the export of revolution discourse, attention to economic variables in foreign policy and changes in foreign policy language.
