Swift global transformations in international relations; the emergence of new communications that provide instant dissemination and transfer of information; increase number of international actors - all above mentioned put on the agenda further search for more effective forms and mechanisms for coordinating activities of public authorities in foreign relations for both Ukraine as well as any other country. Research of the regulatory legal mechanism of coordination of the activities of public authorities of Ukraine in foreign relations shows that Ukraine belongs to a group of countries with a "rigid" form of coordination, that is characterized by stringently regulated sphere of foreign relations, broad powers conferred on the center of coordination as well as the mandatory accountability of all authorities to this center. It was also found that the vast majority of regulations are a post factum reaction to certain violations made by the authorities whose international activity was not agreed with the Ministry of Foreign Affairs and caused negative consequences for Ukraine's image on the international arena. The above indicates that the current level of coordination of activity of state authorities of Ukraine in the sphere of foreign relations is characterized (by a scale developed by Professor of the University of Lausanne Dietmar Brown) as "negative" administrative coordination.
