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...
