In the 21st century, regional economic integration as a less sensitive issue has become the current international trend. In response to the trend of regional economic integration, Russia has changed from traditionally dominated thought of security regional integration to a more geopolitical energy strategy to promote its establishment of the “Eurasian Economic Union” based on the new “Eurasianism.” From the perspective of geopolitical-based energy strategy, the article examines Russia’s geopolitical and energy disputes among the Post-Soviet countries, using the transaction cost economic model as a comprehensive framework. This article believes that Russia, as a rational actor, uses geopolitical energy strategy to reduce transaction costs. Finally, this article uses transaction cost variables to further analyze the bargaining power of the former Soviet Union countries and Russia.
