Middle Corridor Freight Hits 4.5 Million Tons as South Caucasus Cements Eurasian Trade Role

The Trans-Caspian International Transport Route — commonly known as the Middle Corridor — processed 4.5 million tons of freight in 2024, a figure that represents a more than fivefold increase from the 840,000 tons recorded as recently as 2021. Container traffic grew approximately 260% to around 50,500 twenty-foot equivalent units (TEUs), while some short-period comparisons have shown demand spikes of 450 to 500 percent relative to prior-year baselines. The South Caucasus has established itself as the fastest-growing Eurasian logistics corridor, transforming what was once an underutilised alternative trade route into a strategically indispensable artery for China-Europe commerce.
The corridor links China and Central Asia to Europe via the Caspian Sea, Azerbaijan, Georgia, and onward through Turkey to the Black Sea and Mediterranean. Its rise is directly attributable to the search by global shippers for alternatives to the Trans-Siberian Railway — which transited Russian territory — following the disruptions and sanctions environment created by Moscow's 2022 invasion of Ukraine. The corridor has since attracted significant attention from major shipping lines, logistics companies, and institutional investors in Europe, China, and the Gulf.
The European Commission published a major EU-funded meta-study in February 2026 mapping investment needs along the corridor, identifying missing or outdated infrastructure segments and providing a prioritised blueprint for capital allocation. The study, undertaken as part of the EU's Global Gateway initiative, is understood to identify approximately $38 billion in investment requirements across transport, energy, and digital connectivity segments linking Europe to Central Asia via the Caucasus. The European Commission noted that the study provides the analytical foundation for Global Gateway investment decisions over the 2026–2030 planning horizon.
Azerbaijan plays the central role in the corridor's architecture. The country serves as the indispensable land and Caspian Sea transit hub, connecting Kazakhstan and Turkmenistan in the east to Georgia and Turkey in the west. The Baku International Sea Trade Port at Alat — one of the Caspian's largest modern ports — has expanded its handling capacity and now serves as the primary trans-shipment node for Chinese and Central Asian cargo moving westward.
Georgia's Black Sea ports of Poti and Batumi are the corridor's western terminals, where cargo transfers to Black Sea shipping for onward transport to Romanian, Bulgarian, and Ukrainian ports, or routes overland through Turkey. Port expansion investment at both Poti and Batumi is underway to meet growing throughput demand, with completion of new container berths expected by 2027. The Astana Times highlighted the corridor's growing significance for Kazakhstan and the broader Central Asian economies, which are increasingly dependent on the route for their access to European markets.
Infrastructure bottlenecks remain the corridor's primary constraint. Rail capacity limitations in Azerbaijan and Georgia, combined with insufficient ferry capacity on the Caspian, prevent the route from operating at its theoretical throughput potential. The Horadiz-Aghband railway in Azerbaijan — a missing link in the corridor's network — is scheduled for completion by end-2026 with a 15 million ton annual capacity, which will materially expand the system's ability to handle heavy freight.
Digitalization is the next frontier. Corridor operators are implementing single-window customs and logistics coordination platforms designed to reduce transit times — currently averaging 12 to 15 days for China-to-Europe containers — to below 10 days by 2027, making the route genuinely competitive with maritime alternatives on speed as well as geopolitical reliability.
For investors, the Middle Corridor's growth trajectory represents one of the most compelling infrastructure investment themes in the Eurasian space, with a long runway of capacity expansion ahead.
