Connectivity

In recent years, Eurasia has undergone a structural transformation in how regions connect, trade, and cooperate. The combination of geopolitical shocks, disrupted supply chains, and the search for secure east–west routes has elevated the importance of the Trans-Caspian space. The states of Central Asia, once constrained by geography, have taken unprecedented steps to strengthen regional coordination, modernize infrastructure, and integrate more closely with Europe. Meanwhile, Azerbaijan has rapidly emerged as an indispensable connector linking Central Asia with the South Caucasus, Türkiye, and European markets. This new reality was formally acknowledged in November 2025 when Azerbaijan was unanimously welcomed as a full participant in the Consultative Meeting of Central Asian Heads of State in Tashkent. What had long been a C5 grouping transformed into a C6, marking a historic moment: the Caspian was no longer a frontier separating two regions but the center of a unified geopolitical and geo-economic space. President Ilham Aliyev described this alignment as the emergence of “a single geopolitical and geo-economic region,” while President Shavkat Mirziyoyev called Azerbaijan’s inclusion “historic” and proposed transforming the consultative platform into a structured regional institution capable of shaping security, economic, environmental, and digital policy. The Caspian is no longer a boundary; it is the heart of an integrated region. The transformation of the EU and U.S. C5+1 formats into C6+1 is the logical next step to ensure that both sides of the Caspian advance together – coherently, strategically, and with shared purpose.
