This article examines the impact of the Ukraine war on Russian–North Korean relations at three different levels. At the international level, the war will bring two power groups into confrontation. The closer security cooperation between Russia and China will form an illiberal group that will set the security environment for North Korea to establish a new international identity. At the regional level, Russian–Chinese security alignment will be reinforced, which North Korea will exploit. At the bilateral level, Russian–North Korean relations will be strengthened as Russia’s influence in Northeast Asia wanes.

The purpose of this short paper is to introduce a new concept and way of thinking about the future of Northeast Asia in conjunction with the development of Russian Far East and Eastern Siberia. The basic arguments of this paper are: first, the specialists should shed the conventional definition of geographical boundaries, especially in defining Northeast Asia; second, Russia's Far Eastern development can make a significant contribution to the regional community building depending on how creatively and imaginatively the development proceeds; lastly, it is high time to start preparation for the future of Northeast Asia before it gets too late. In this regard, at the end of this paper the authors introduce their initial effort to establish a consortium, the purpose of which is to lay groundwork for the establishment of an institute for Northeast Asian community building.
