Japanese-Russian-Ukrainian geopolitical triangle: mutual influences of the parties

Abstract

The study revealed mutual influences within the conditional triangle "Japan-Russia-Ukraine" that have consequences for the security situation on a global scale. It clarifies how security and territorial integrity (of Ukraine and Japan) affected the content and nature of Japanese-Ukrainian, Japanese-Russian, and Ukrainian-Russian relations. The study aimed to determine how the positions of any two states from the modeled conditional triangle concerning a third state influence the content and nature of their relations. The research methodology is based on institutional analysis, with the help of which the decisions and positions of the state institutions of Japan, Russia, and Ukraine, as well as their consequences for security at the regional and global levels, are studied. It is proved that the Ukrainian issue affects the content and nature of Japanese-Russian relations with upward dynamics throughout the entire period of the Russian aggression against Ukraine (2014-2023). The analysis of the processes in the triangle "Japan-Russia-Ukraine" demonstrated that the security of Europe and Asia might no longer be separated as autonomous processes.
