Kazakhstan and Azerbaijan Are Reinforcing the Middle Corridor’s South Caucasus Link
On April 7 Kazakhstan’s Foreign Minister Yermek Kosherbayev visited Tbilisi to hold talks with Georgian Foreign Minister Maka Bochorishvili and sign a 2026–2027 foreign-ministry cooperation program. He called Georgia “a key link” in the Europe–Asia transport architecture and said the common task was to raise corridor capacity, improve service predictability, and ensure tariff transparency. The materialization of the bilateral cooperation is already evident from last June’s opening of the Poti multimodal terminal by a joint Kazakhstani-Georgian company.
The real meaning of Kosherbayev’s discussions in Tbilisi lies in their context. On April 2 in Baku, Prime Minister Olzhas Bektenov said Kazakhstan plans an intergovernmental agreement with Azerbaijan this year to strengthen the status of the Middle Corridor (also known as the Trans-Caspian International Transport Corridor, TITR), and he proposed moving quickly on the Digital Monitoring Center under the Organization of Turkic States (OTS). On April 6 in Tbilisi, Azerbaijani President Ilham Aliyev called the Azerbaijan–Georgia segment the corridor’s “main transport artery.” Then on April 8 in Baku, Aliyev received Kosherbayev together with Kazakhstan’s transport minister. The official readout ranged from the Middle Corridor to joint investment, green-energy, and fiber-optic projects. Kosherbayev’s April 7 stop in Tbilisi thus belongs to a short Kazakhstan-led diplomatic run across the corridor’s western nodes.
Kazakhstan and Azerbaijan Tighten the Corridor
Kazakhstan’s early-April engagement in the South Caucasus rests on its eastward-looking framework with China. Two China–Kazakhstan documents were already in evidence in October 2023: a Memorandum of Understanding (MoU) on deepening the development of the China-Europe Railway Trans-Caspian route, and an intergovernmental agreement on developing that route. China’s National Development and Reform Commission (NDRC) subsequently clarified that the agreement focused on stronger transit organization, fewer administrative barriers, and improved logistics and transport operations. In July 2024, Kazakhstan’s President Kassym-Jomart Tokayev and his Chinese counterpart Xi Jinping jointly attended the opening of the Trans-Caspian direct fast transport service; NDRC then recorded a work mechanism with Kazakhstan’s transport ministry to carry that cooperation forward.
On January 1, the first Trans-Caspian train of 2026 departed Xi’an for Baku carrying 45 containers of photovoltaic equipment. Chinese reports assert that the route had accumulated 466 runs by the end of November 2025, moved onto a weekly six-outbound and three-inbound timetable, and cut travel times from the roughly 20-day average recorded in 2025 to a standard 15 days, with the fastest runs taking 11 days. On April 3, it was also reported that there were 85 Xi’an Trans-Caspian trains in the first quarter of 2026, up 150% year-on-year, while the Kazakhstan–Xi’an terminal in Almaty handled more than 6,000 containers in that quarter alone, a 60% increase from a year earlier. A separate quasi-official Chinese trade-services portal reported that Trans-Caspian trains had reached daily service and that 371 such trains had run in January–October 2025, up 33%. China’s NDRC also said in late 2025 that Aktau and Baku should be strengthened as hub nodes in this corridor system.
Azerbaijan is the indispensable partner without which the route’s western logic does not function. Bektenov’s April 2 statement made that plain by tying the corridor more closely to Baku, and by pushing institutional coordination and digital monitoring. Aliyev’s April 8 reception of Kosherbayev and Transport Minister Nurlan Sauranbayev widened the picture beyond transit in the narrow sense toward joint investment and linked infrastructure. The Trans-Caspian Green Energy Corridor and fiber-optic lines across the Caspian point in the same direction: they show an effort to turn bilateral political alignment into practical management across transport and communications.
Still, the route has to become commercially normal at the Black Sea end: this is where Georgia comes into play in Kosherbayev’s April 7 talks. The most tangible materialization of this is the Poti terminal. Georgia’s economy ministry said the project involved $31.5 million in investment, more than nine hectares of terminal area, and a first-stage annual throughput of more than 80,000 containers. Kazakhstan’s readout of Kosherbayev’s April 7 meeting linked the corridor directly to Georgia’s role in Europe–Asia logistics and to Kazakhstan’s investment footprint in the Georgian economy, now above $600 million.
The Azerbaijan–Georgia Axis Holds the Western Segment
Kosherbayev did not visit Georgia as a narrowly defined South Caucasus specialist. He is one of the senior operators available for politically sensitive files that combine foreign policy, transport, and intergovernmental coordination. He has been foreign minister since September 2025, after serving as deputy prime minister earlier that year, and before that as deputy foreign minister and ambassador to Russia. His movement from Tbilisi to Baku, including Aliyev’s reception of him alongside Kazakhstan’s transport minister, shows that Astana is handling this route at ministerial weight and through a figure who combines cabinet rank with diplomatic practice and state-to-state execution.
Georgia’s position is more important precisely because it is no longer guaranteed. While the IMF’s April 7 mission statement said a more protracted Middle East conflict could redirect additional transit toward Georgia along the Middle Corridor, it also mentioned that an Azerbaijan–Armenia peace agreement could generate new trade routes bypassing Georgia. Astana therefore has good reason to reinforce the Azerbaijan–Georgia segment, and Kosherbayev’s visit is a part of that effort, because it remains the operative route, not because it can take for granted that this will indefinitely remain the only serious western-facing option.
Aliyev’s remarks in Tbilisi on April 6 clarify why the Azerbaijan–Georgia axis remains the route’s present backbone. He said Azerbaijani oil and gas exports begin through Georgia, that oil from the eastern shore of the Caspian also moves through Azerbaijan and Georgia, and that transport corridors that were later built along those same routes are now being expanded. Aliyev then stated plainly that the Middle Corridor passes through Azerbaijan and Georgia, and is “our main transport artery.” This also aligns closely with Kazakhstan’s current westbound effort and the setting for Kosherbayev’s visit: Georgia is the Black Sea–facing outlet, but the route reaches that outlet through Azerbaijan’s Caspian ports and onward transport system into Georgia.
The present phase also has a retrospective logic. Kazakhstan, Azerbaijan, and Georgia were already moving toward more formalized corridor management in June 2023, when they agreed to establish a joint logistics company to unify tariffs, apply a one-window principle, and handle cargo movement on the TITR on a coordinated basis. At the time, Kazakhstani officials said that the aim was to cut delivery times first to 18 days and then to 10–15 days, while bottleneck-removal measures included a container hub in Aktau, rail expansion on the Kazakh side, and steps to regularize container handling along the route. The past week’s diplomacy should therefore be seen as a further tightening of machinery already under construction for several years.
The larger economic case remains favorable if the route can be made more reliable. The World Bank’s 2023 corridor study argued that the Middle Corridor is not only a land bridge between China and Europe, but also a regional corridor in its own right. Its modeling projected a 37% increase in trade among Azerbaijan, Georgia, and Kazakhstan, and a 28% increase in trade between those countries and the EU by 2030, provided that coordination, logistics, digitalization, and infrastructure upgrades are carried through. The Bank also put the matter in practical terms: higher freight volumes and shorter transit times depend on synchronized procedures, better ports, and more continuous operations. This is the policy setting in which Kazakhstan and Azerbaijan are now seeking to make the corridor function more predictably from the Chinese feeder side through the Caspian and into the South Caucasus.
Kazakhstan and Azerbaijan Move to Preserve Georgian Corridor Continuity
Neither Kazakhstan nor Azerbaijan is a mere participant in corridor construction. Astana is trying to shape corridor continuity, but it can do so only through indispensable cooperation with Baku. Kosherbayev’s visible role underscores the point. The route depends on ports, railways, terminals, tariffs, and schedules, but it also depends on working political relationships among the states that control those assets. Kazakhstan is thus not waiting for a broader regional realignment to settle itself through the westbound chain. Rather, with Azerbaijan, it is acting through ministerial visits, proposals on digital coordination, and repeated coordination with Georgia.
The South Caucasus segment of the Middle Corridor has become central to Central Asia’s westward optionality, as The Times of Central Asia previously reported on February 13 and on March 17. This week’s Kazakhstan–Georgia–Azerbaijan sequence confirms that judgment from a more practical angle. The TRIPP (“Trump Route for International Peace and Prosperity”) route through southern Armenia and other alternative alignments may yet widen the region’s routing possibilities. The IMF is right to note that some future routes could bypass Georgia, but the existing Azerbaijan–Georgia line remains the operative channel today. Accordingly, Kosherbayev’s stop in Tbilisi and the document signed there mean that Kazakhstan is acting at the ministerial level, through working relationships, to govern terminals and manage the route more deliberately.
