Since the dissolution of the Soviet Union in 1991, Türkiye has regarded integration with the Turkic world as one of the principal objectives of its foreign policy. Although this process has experienced periodic interruptions, it acquired an institutional framework with the establishment of the Organization of Turkic States (OTS) in 2021. Among the relationships within the Turkic world, the strategic partnership between Türkiye and Azerbaijan has evolved to a more advanced level than the others. This has been driven not only by historical, cultural, and geographical ties, but also by the fact that Russia’s influence over Azerbaijan has remained more limited than its influence over the other OTS member states.
While Türkiye serves as Azerbaijan’s principal gateway to Europe and the Western world, Azerbaijan constitutes Türkiye’s essential link to Central Asia. Energy security, increasing the capacity of the Middle Corridor, ensuring stability in the South Caucasus, limiting Russian influence over Armenia, and managing the geopolitical implications of developments related to Iran constitute the main pillars of the strategic partnership between the two countries.
The process initiated by Russia’s full-scale invasion of Ukraine in 2022 has ushered in a new geopolitical era, both for European security and for the Türkiye–Azerbaijan axis. The resurgence of Russia’s revisionist policies, its use of energy supplies as an instrument of political coercion, and, subsequently, the uncertainties surrounding the future of the long-standing American security umbrella following the return of the Donald Trump administration have compelled Europe to seek new approaches to both security and energy.
Against this backdrop, the European Union has sought not only to secure access to alternative energy resources and critical raw materials but also to develop a comprehensive connectivity strategy with Central Asia under its Global Gateway initiative. To this end, the EU has announced approximately €12 billion in financing for transport, energy, and digital infrastructure projects linking Europe with Central Asia. Armenia’s demonstrated political willingness to participate in these connectivity initiatives also represents a noteworthy development for both the establishment of lasting peace in the South Caucasus and the expansion of regional connectivity.
This connectivity is of strategic significance not only for Europe’s energy security and resilience against Russia, but also for the Central Asian states, Azerbaijan, Georgia, and Armenia, all of which seek to reduce their dependence on Russia’s sphere of influence. It is equally important for Türkiye, as it reinforces the long-term sustainability of the vision of the Turkic world that Ankara has pursued since 1991.
Nor does this process fundamentally contradict China’s strategic interests. From Beijing’s perspective, it would not be desirable for the Middle Corridor—the safest and most stable route connecting China with Europe—to return entirely under Russian control. Although the United States has yet to formulate a comprehensive “Greater Central Asia Strategy,” its support for strengthening Trans-Caspian connectivity and the institutionalization of leaders’ dialogues with the Central Asian states demonstrate Washington’s growing interest in the region.
Nevertheless, these positive developments have largely been made possible by the geopolitical environment created by Russia’s preoccupation with the war in Ukraine. Should the conflict conclude on terms acceptable to Moscow, it is highly likely that Russia will once again shift its strategic focus toward the South Caucasus and Central Asia in an effort to re-establish the influence it has lost.
For this reason, the absence of a permanent peace agreement between Azerbaijan and Armenia remains one of the region’s most significant vulnerabilities. Unless the disputes between the two countries are fully resolved, potential flashpoints susceptible to Russian intervention will continue to exist. Azerbaijan, thanks to its energy resources, economic capacity, and strategic partnership with Türkiye, possesses considerable resilience against Russian influence. By contrast, any renewed orientation of Armenia and Georgia toward Russia’s sphere of influence could weaken the most critical link in the connectivity corridor between Europe and Central Asia.
Accordingly, sustained support by the European Union and the United States for the economic development of the South Caucasus is not merely a matter of promoting regional prosperity; it is also a strategic necessity for safeguarding Europe’s long-term security interests.
At the same time, a second risk deserves careful attention. If European and American efforts to promote peace and enhance connectivity in the South Caucasus are pursued without adequately placing Türkiye at the center of these initiatives, their overall effectiveness may be significantly diminished. In reality, Türkiye is an indispensable actor for ensuring lasting peace in the South Caucasus, safeguarding the security of regional transport corridors, and sustaining economic integration. Its strategic geographic location, NATO membership, regional influence, and strategic partnership with Azerbaijan collectively position Türkiye as one of the region’s natural security providers.
In conclusion, the emerging European security architecture should not be viewed solely as a framework for the defence of the European continent. It must also encompass the preservation of secure and uninterrupted connectivity between Europe, the South Caucasus, and Central Asia. Achieving this objective requires safeguarding the independence and sovereignty of the regional states, preventing Russia—or any other major power—from establishing a new hegemonic order, resolving the conflicts in the South Caucasus on a permanent basis, and supporting the region’s long-term economic development.
Ultimately, these objectives can only be achieved by recognizing Türkiye as an integral component of the Euro-Atlantic security architecture and as the principal strategic actor connecting the South Caucasus with Central Asia. The Türkiye–Azerbaijan axis is well positioned to become not only a cornerstone of regional stability but also one of the fundamental pillars of Europe’s long-term security in the emerging strategic order.
