Introduction International relations theory is a discipline that focuses on international relations and forms a theoretical framework. It aims at creating a set of concepts that allow analyzing existing international relationships. A disciplinary label is based on structural and sociological aspects (Grenier, Turton & Beaulieu-Brossard 2015). It is very important for specialists in this field as it provides an opportunity for profound research. There are the three most significant theoretical models in international relations theory. These are realism, liberalism, and constructivism. All existing theories related to the subject are divided into two categories: positivism and reflectivism. However, the former is the most relevant nowadays. This concept is mostly promoted by Western specialists, and it has the most significant impact on the international community. However, there are some non-Western theories. For example, several universities in China work on their concepts of diplomacy and international relationships, but they are not very popular yet. Also, some other non-Western states offer their visions on this subject. Nonetheless, they do not actively participate in the international discussion. Therefore, many specialists claim that the Western international relations theory is the only one that can address existing problems. The main goal of this paper is to discuss the reasons that led to the dominance of the Western international relations theory. International Relations Theory International relations theory is a complex subject that involves various concepts and ideas. The most accurate point of view of the theory is pluralist as it includes positivist, materialist, social, and constructivist understandings. Also, the theory focuses on systematic ideas that are aimed to improve the understanding of the social world. In addition, history is very important to international relations theory. It reveals various models of development and reflects their distinct characteristics. There are several aspects that characterize international relations theory. First, it should be accepted as a theory by the majority of specialists in the international relations community. Second, it should be self-identified by its designers as international relations theory in spite of the fact that it might not be substantially acknowledged by academic international relations community. Third, it should have a systematic structure that generalizes ideas that matter for international relations. There are different theories related to the subject, but most of them are developed by and for the West. They are mostly based on the idea that the history of the West is the history of the world. The most prominent Western sources of international relations theory successfully distribute its subjects globally. However, many specialists claim that this theory does not exist at all. Nonetheless, all countries are now actively engaged in international relations despite many players in the periphery having much independence ­(Tickner 2013). However, different non-Western countries substantially invest in their international images and try to create their own concepts. Therefore,
