The Western Balkans has been and remains a particularly dense zone in terms of the number of actors present, where the interests of all the leading actors in world politics are bizarrely intertwined. The Ukrainian crisis has added spice to the Balkan agenda, reviving “frozen conflicts” not only within the borders of the region but also beyond its perimeter. Directly dependent on the outcome of the armed confrontation in Ukraine and separately from it, a clash or, at least, an intensification of external actors in the Balkan direction seems inevitable. The historical-systemic approach used in the study and the paradigm of multipolarity made it possible to trace the probable directions of activity of both regional and external actors. Based on a wide range of sources, the work provides a panorama of the foreign policy positioning of regional capitals; identifies major and minor external actors; shows the transformation of approaches and practical steps of key actors through the prism of the ongoing crisis. External actors - the European Union (EU), China, Great Britain, Russia and the United States - are divided into groups in accordance with their positions regarding the pre-crisis Balkans and the Balkans in the face of the fierce confrontation between Russia and the West. Among Western interests, special attention is paid to Great Britain, whose activity in the Western Balkans after Brexit is affiliated with the West in general, but not with the United States (despite all the history of strategic partnership in the region) and, moreover, with the EU separately. Against the background of the dominance of Western institutions in the region, the paper traces, however, the growing role of China, as well as external actors of the “second plan” with an oriental flavor: Türkiye, Iran, and the states of the Persian Gulf. An analysis of Russia’s prospects in the region has shown that the crisis in the system of international relations has largely nullified the results achieved earlier. The degree of Russia’s involvement in the crisis raises the question of its resource capacity, the ability to further maintain its own positions. Additional difficulties will be associated with the consolidated efforts of the Western allies and other external actors, including China, to balance Russian influence and presence in the Western Balkans.
