There is an old dictum in geopolitics: whoever controls the pipes controls the politics. For Central Asia — a region sitting atop enormous reserves of oil, gas, and critical minerals, yet landlocked and dependent on others’ territory to reach global markets — this has never been more consequential. In 2025 and 2026, the region’s energy transit architecture is being remade at a pace not seen since the Soviet collapse. Old routes are being questioned, new corridors are being built, and the competition to shape Central Asia’s export geography has become one of the defining contests of Eurasian geopolitics.
The Russian Bottleneck: A Dependency Under Strain
For decades, Central Asian energy had one dominant exit: northward, through Russia. Kazakhstan exports approximately 80 percent of its oil via the Caspian Pipeline Consortium route through Novorossiysk. This arrangement was economically convenient and politically loaded — Moscow’s control over transit gave it structural leverage over Astana that went far beyond any formal agreement.
Russia’s invasion of Ukraine changed the calculus. Periodic attacks on Black Sea ports undermine the stability of supplies, so Kazakhstan is now actively seeking alternative ways to diversify export routes. The message from Astana is clear: dependence on Russian transit infrastructure is a vulnerability that must be reduced, even if it cannot be eliminated overnight. In 2024, nearly 93% of Kazakhstan’s oil exports were still transported via Russian pipelines or Baltic sea ports — a figure Astana is deeply uncomfortable with.
The shift is structural, not rhetorical. Following Russia’s invasion of Ukraine, the EU’s crude oil imports from Kazakhstan increased by 48%, positioning the country as the EU’s third largest supplier after the US and Norway. European demand for Kazakh oil is growing rapidly — but accessing that demand without crossing Russian territory is one of the central infrastructure challenges of our era.
The Middle Corridor: From Alternative to Artery
Enter the Middle Corridor — formally known as the Trans-Caspian International Transport Route (TITR). Stretching from Lianyungang port in China’s Jiangsu province to Aktau in western Kazakhstan and Baku in Azerbaijan, the Middle Corridor provides the shortest rail route connecting Europe and China — some 3,000 kilometres shorter than alternative northern routes.
The corridor’s rise has been dramatic. In 2024, cargo volume along the Middle Corridor across the Caspian Sea increased by more than 63 percent year on year, reaching 4.1 million tons, compared with 500,000 tons before Russia’s invasion of Ukraine. By 2025, total container traffic reached 76,900 TEUs, marking a 36 percent increase compared with 2024. The speed advantage is significant: cargo transit along the route takes around 15 days, whereas the traditional sea route requires approximately 45 to 55 days.
Geopolitical crises have accelerated this trajectory. Instability in the Middle East and threats to the Strait of Hormuz have pushed international shippers toward overland alternatives, and the Middle Corridor has effectively become a safeguard against further disruptions to traditional shipping lanes. The corridor is no longer a contingency — it is becoming a primary route.
Azerbaijan: The Indispensable Hub
No country has benefited more from the corridor’s rise than Azerbaijan. Baku has positioned itself as the essential transit node between Central Asia and European markets, and its strategic importance is only growing.
After delivering Kazakh oil to the western shore of the Caspian Sea, it can be transported by rail and the Baku-Supsa pipeline to Georgia’s Black Sea ports, or via the Baku-Tbilisi-Ceyhan pipeline directly to oil traders on Turkey’s Mediterranean coast. Azerbaijan’s role was formalized further in late 2025, when Azerbaijan was formally admitted as a full participant in what had been the C5 format of Central Asian presidents — a recognition of how deeply Baku’s transit and energy interests have become intertwined with those of the region.
The deepening of the Kazakhstan-Azerbaijan strategic relationship is striking. A new fiber-optic cable agreement signed in March 2025 establishes a 380-kilometer undersea connection between Sumqayit and Aktau — part of the broader Digital Silk Road — converting the corridor from a physical transit route into a distributed digital platform capable of supporting real-time adaptive coordination. Infrastructure, energy, and information are being integrated into a single strategic system.
The Bottlenecks: Real and Urgent
Despite the momentum, the Middle Corridor faces serious structural constraints that no amount of political goodwill can quickly overcome.
Rail networks in Azerbaijan and Georgia are struggling with shortages in locomotives and wagons, leading to congestion. Maritime transport across the Caspian Sea is another severe bottleneck due to limited vessel availability, outdated port infrastructure, and slow cargo-handling processes. The numbers confirm the strain: the Baku-Tbilisi-Kars railway line has effectively reached its physical capacity, with traffic increasing by 35 percent in a single week and train queues at border crossings stretching for several kilometers.
Georgia remains the corridor’s most vulnerable link. The Georgian government has slashed the new Anaklia port’s 2026 funding from 150 million lari to 50 million lari — a decision that baffles corridor planners, given that the port has been identified by both the World Bank and the EU as a central priority. Without Anaklia, Georgia’s existing port capacity will be overwhelmed.
There is also a longer-term environmental threat. A projected sea level drop of up to 6.5 meters in the Caspian Sea could leave current berths landlocked by 2045, potentially forcing a transition from shoreline operations to offshore deep-water terminals — requiring constant multimillion-dollar dredging to remain functional. The Middle Corridor, as currently configured, may have a limited shelf life.
Turkmenistan’s Gas and the China Lock-In
While Kazakhstan’s oil looks increasingly westward, Turkmenistan’s gas tells a different story. Turkmenistan alone accounts for approximately 45% of China’s pipeline gas imports — a dependence that runs in both directions. Ashgabat is heavily reliant on Beijing as its primary customer, and Beijing has no interest in loosening that grip.
The Central Asia–China gas pipeline was the first to bring Central Asian natural gas to China, and Chinese officials have described it as “a supply channel with strategic value that supersedes commercial concerns.” The planned Line D expansion — which would add significant capacity through Tajikistan — has been stalled for years. During the C5+1 summit in Kazakhstan in June 2025, Chinese President Xi Jinping spoke only vaguely about boosting natural gas cooperation, suggesting Beijing is in no rush to formalize terms that might give Ashgabat more leverage.
The proposed Central Asian Gas Ring offers a partial answer: this regional infrastructure initiative could stabilise supply, diminish the risk of blackouts, and create export pathways to South Asia and Europe, especially through the Middle Corridor. But the project faces its own obstacles, including ageing infrastructure — reports suggest up to 70% of some Central Asian pipelines are worn out — and diverging national priorities between gas-rich and hydro-dependent states.
The European Bet: Green Corridor, Strategic Interest
Europe’s engagement with Central Asian energy transit has shifted from peripheral interest to strategic priority. At the first EU-Central Asia summit in April 2025, the EU announced investments of €12 billion targeted at developing infrastructure and transport, with a focus on critical raw materials, digital connectivity, and energy.
The logic is clear: Europe needs to reduce dependence on Russian energy and Chinese supply chains simultaneously, and Central Asia sits at the intersection of both problems. The EU’s relevant regulations banning new Russian energy contracts have been approved by the European Parliament in late 2025 and are expected to be approved by the European Council early in 2026. The legal architecture for diversification is being built — but the physical infrastructure must follow.
The CASA-1000 project illustrates the ambition: this major regional infrastructure initiative is designed to transmit up to 1,300 megawatts of surplus hydropower from Kyrgyzstan and Tajikistan to energy-deficit markets in Afghanistan and Pakistan. As of 2025, construction in Kyrgyzstan and Tajikistan was largely complete, with commercial operations expected to begin between 2026 and 2027. Energy transit in Central Asia is no longer only about hydrocarbons — it is becoming a platform for the broader energy transition.
Conclusion: The Geography of Sovereign Choice
What is unfolding in Central Asia’s energy sector is not simply a rerouting of pipelines. It is a fundamental restructuring of sovereign options. For decades, Central Asian states could not meaningfully choose who carried their energy to market — geography and infrastructure made Russia the default. That default is now being dismantled, corridor by corridor, agreement by agreement.
The Middle Corridor will not replace the Russian route overnight. Kazakhstan will be able to transport no more than one-third of its oil via alternative routes in the foreseeable future, and the majority will continue to flow via the Caspian Pipeline Consortium through Russia. But the direction of travel is unmistakable.
Central Asian governments understand that energy transit is not just economics — it is the infrastructure of independence. Every ton of oil that moves through Baku rather than Novorossiysk, every cubic meter of gas that reaches a new market, every kilometer of new railway built outside Russian territory is a quiet assertion of sovereignty. In a region where geography was once destiny, infrastructure is becoming the instrument of choice.
