This article sets out to examine how Azerbaijan strategically navigates its engagement within diverse multilateral organizations – namely the Commonwealth of Independent States (CIS), the Non-Aligned Movement (NAM), the Organisation of Islamic Cooperation (OIC), and the Organisation of Turkic States (OTS) – and leverages its energy diplomacy and regional alliances to advance its core national interests and enhance its influence in the evolving international system. The primary focus of this study is an examination of Azerbaijan’s multilateral performance, notably its energy diplomacy, regional ties, and multilateral engagement with regional and cross-regional organizations. Through its proactive energy and pipeline diplomacy, which stretches to Europe through Georgia and Türkiye, Azerbaijan can leverage its energy resources to enhance its position in the international system. Azerbaijan has developed a diplomatic strategy that encompasses several geopolitical approaches to maintain stable partnerships with international institutions and protect its core national interests. This study finds that Azerbaijan strategically utilizes its membership in various multilateral organizations, coupled with its assertive energy diplomacy and the cultivation of regional alliances, as complementary tools to project influence and safeguard its national interests within the dynamic international environment.
