Abstract: Russia’s growing energy cooperation with China is central to several of Moscow’s top foreign-policy objectives. Analyzing what drives Russia’s energy diplomacy with China can therefore shed important light on the dynamics of Russian foreign policy-making. We go beyond other recent studies of this topic by examining the role of domestic political influences and the countries’ bilateral interactions. We show that personalist elements influence both Russia’s policy-making and its diplomacy with China. The personalism has made it hard for Russia to coordinate the relevant decision-making institutions and get the most from its energy strength. The economic gains from recent energy deals, particularly to Russia’s Far East, have been less than expected, and Russia has met only limited success in achieving its foreign-policy priorities in the Asia-Pacific region. Moving forward, Russia must further institutionalize its decision-making process, limit the role of personalism, and better coordinate the activities of its energy firms with the goals of its central agencies and local governments.
