Abstract: This paper is an attempt to analyze Russia’s regional political place and power in Northeast Asia through the US-China-Russia triangularity and to forecast the future of Russia’s place in the region by applying the basic logic and concepts of social network theory such as “social capital” and “structural hole.” From Russia’s perspective, the structural hole that formulated as a result of its own de-link strategy in the 1990s has developed into a determining factor in disabling Russia from regaining its position and influence in the Northeast Asian region. To overcome this obstacle, Russia has continuously developed its diplomatic strategies and reviewed the potential for cooperating with the US. Nonetheless, the US-Russian rivalry and competition at the global level is severely damaging an opportunity for the coming of a stable and cooperative order in Northeast Asia. However, the works of the US utilizing Russia without excluding China, and establishment of a vision for a regional order in the context of fostering stability and cooperation will become an utmost important factor in developing peace and co-prosperity in Northeast Asia. A sort of a semi-triangularity among the US-China-Russia seems more beneficial for regional stability and cooperation.
