Abstract: The research subject covers different aspects of institutional participation of the Republic of Armenia in the EU “Eastern Partnership” program. Armenia, though actively participating in integrational processes within the European Economic Union, considers cooperation with the EU, and the “Eastern Partnership” program in particular, as an effective instrument of implementation of its own national interests. The author considers the political and legal structure of the “Eastern Partnership” initiative, analyzes the political context and the formats of Armenia’s participation in the initiatives of the “Eastern Partnership”, determined by Armenian government’s intention to use the potential of the EU to long-term political issues. The author analyzes the problem in the context of the neoliberal paradigm and focuses on the multidimensionality of the problem under study, taking into account the complexity of the modern system of international relations characterized by integration tendencies. The author comes to the following conclusions:
-         At the present time, the intention of Armenian government to pursue the complementary pragmatic foreign policy, aimed at the implementation of its own national interests, using the potential of cooperation with the leading geopolitical actors within the priority cooperation with the Russian Federation and integrational associations, sponsored by it, is obvious;
-         Armenia prefers maintaining the possibilities of cooperation with the EU within the “Eastern Partnership” and modernizes legal basis of cooperation with the EU, at the same time opting for strategic partnership with Russia. In this context, the author emphasizes Armenia’s intention to pursue the “reasonable pragmatic neutrality policy” using the contradictions between the leading subjects of regional policy – the European Union and Russia.
-         It seems that the mentioned intentions are promising, since the EU is still interested in Armenia, first of all because of the necessity to use the potential of former Soviet republics to counterbalance Russia’s policy.
-         Thus, bilateral cooperation between Armenia and the EU within the “Eastern Partnership” initiative is, undoubtedly, quite promising.
