Ukraine crisis is a reflection of the geopolitical competition of great powers to achieve global and regional hegemony. The Islamic Republic of Iran has not explicitly condemned Russia's military attack on Ukraine and has declared the West, especially America, to be the main cause of the crisis. In this regard, article seeks to answer the question, "Which ideas and components have shaped Iran's foreign policy approach to Russia's military invasion of Ukraine?"
In response, it can be said that "the internal structure of the political system of the Islamic Republic and the perception of its decision-makers about the changes in the structure of the international system and the change in the position of its major actors have shaped the approach of Iran's foreign policy towards this crisis". Despite the declaration of neutrality, Iran has supported Russia's invasion of Ukraine due to the dominant strategy of "orientalism" in foreign policy and with the aim of weakening the global position of Western countries. According to Iranian officials, Russia's invasion is the beginning of a transformation in the international system, which gives Tehran the opportunity to act in the world arena. The article examines Iran's foreign policy in the Ukraine crisis with a qualitative approach and using the method of analyzing events in Tehran-Moscow relations and the impact of structural changes in the international system and Iran's internal politics within the framework of the theory of neoclassical realism.
