As we enter the second quarter of the 21st century, Eurasian geography has begun to occupy the center stage of global power competition, energy supply security debates, and the restructuring of international trade routes. The Central Asia and Caspian basin have gained increasing strategic importance within the scope of great power competition, energy security, and transportation networks. In recent years, the revival of regional partnership mechanisms has reached a new stage, particularly with the acceleration of political and economic rapprochement between Central Asian countries and Azerbaijan. This phase of change has directed regional states not only to pursue a policy of balancing between great powers but also to strengthen horizontal regional cooperation mechanisms among themselves. In this context, one of the notable developments in recent years is the new regional partnership format emerging between Central Asian states and Azerbaijan, informally referred to as the “C6.”
The C6 initiative is evaluated as a multi-dimensional coordination mechanism that addresses regional connectivity, economic integration, and shared security approaches within the same framework, beyond classical diplomatic platforms. In particular, the efforts of the leaders of Kazakhstan, Uzbekistan, and Azerbaijan to present a common regional perspective at international meetings demonstrate that this format is beginning to take shape not only as a symbolic political initiative but also as a regional structure containing concrete policy objectives.[i] This situation indicates a trend toward expanding the cooperation model previously developed within the C5 framework in Central Asia to create a broader regional geoeconomic network that encompasses the South Caucasus.
When regional integration dynamics are considered, the rise of the C6 format is largely linked to transportation corridors, energy partnerships, and investment projects. The development of Trans-Caspian trade routes and the Middle Corridor route establishes a concrete ground for integration between Azerbaijan and Central Asian states through infrastructure projects, port connections, and joint economic ventures.[ii] These projects are viewed not merely as technical arrangements facilitating trade flows, but as strategic stages that create regional economic interdependence, mutual investment relations, and production networks.
The rise of the C6 format is particularly linked to Central Asia regaining importance in global geopolitical competition. The increasing strategic interest of the United States toward this region and the efforts of the leaders of Kazakhstan, Uzbekistan, and Azerbaijan to present a common regional vision within the scope of international meetings held in Washington have strengthened the diplomatic visibility of this process. In this context, the C6 is interpreted as an expanded version of the existing C5 mechanism, and with the inclusion of Azerbaijan, a direct geopolitical bridge is established between the South Caucasus and Central Asia.[iii]
From an economic perspective, the most concrete dimension of the C6 is observed in transportation and trade networks. In particular, Trans-Caspian transport and Middle Corridor projects function as a critical connection between Central Asia and Chinese markets via Azerbaijan’s Baku and Alat ports. The development of this corridor is supported by infrastructure investments, energy projects, and joint production initiatives; the establishment of investment funds by Azerbaijan with Kazakhstan, Uzbekistan, and Kyrgyzstan is evaluated as an element deepening economic integration. Consequently, transportation links become not merely technical projects increasing trade volume, but strategic tools that generate regional economic interdependence and mutual interest.
Another important dimension of the C6 partnership is the discussions on institutionalization. Regional experts state that the platform should not consist solely of meetings at the leadership level; on the contrary, it must be supported by permanent mechanisms, expert networks, and coordination structures.[iv] This approach is related to the fact that common issues—such as regional security threats, environmental problems, and the creation of economic value chains—require coordinated policies. Similarly, at the think-tank conference held in Baku, the necessity of transforming flexible dialogue formats into sustainable partnership mechanisms, developing common positions on international platforms, and transferring humanitarian partnership into institutional structures was emphasized.[v]
When evaluated in terms of security and strategic stability, it is observed that the C6 format offers a partnership-based coordination model rather than a block-based alliance. This model aims to increase collective resilience through joint economic projects, energy partnerships, and transportation security under conditions of global instability. However, from a historical perspective, some researchers interpret this initiative not as an entirely new structure, but as a contemporary continuation of the consultative mechanisms established between the Central Asian republics and Azerbaijan just before the dissolution of the Soviet Union.[vi] This situation demonstrates that regional integration is the result of not only contemporary geopolitical pressures but also the revitalization of historical connections.
In conclusion, the C6 format is a crucial indicator of the emerging trends in regional partnership within Central Asia and the Caspian basin. By bringing together diplomatic dialogue, economic integration, transportation connectivity, and energy partnerships under a single regional scope, this structure presents a multi-layered integration model. With the inclusion of Azerbaijan, Central Asia’s capacity to access the South Caucasus, Türkiye, and the Mediterranean increases; thus, the region gains a more visible position within global trade networks. Furthermore, the long-term impact of this format will depend on the level of institutionalization, the creation of joint financing mechanisms, and the strengthening of political coordination capacity. If this process progresses successfully, the C6 may transcend being merely a regional dialogue platform and become one of the fundamental components of a new geoeconomic partnership architecture in Eurasia.
