Kazakhstan and Iran agreed to accelerate development of the North-South transport corridor and port infrastructure during talks in Tehran on June 16. Deputy Prime Minister Serik Zhumangarin met Iranian Minister Farzaneh Sadeq to discuss expanding bilateral trade and logistics ties. The two sides aim to increase corridor capacity to 20 million tons annually.
Trade Growth and Targets
Bilateral trade between Kazakhstan and Iran rose 26.4% in 2025 to $430.2 million, according to Zhumangarin. The two countries reaffirmed a goal of reaching $3 billion in mutual trade, leveraging the free trade agreement between Iran and the Eurasian Economic Union. The talks built on agreements made at the level of heads of state.
Corridor Expansion Plans
Freight volume on the North-South corridor increased 12% in 2025 to 3.5 million tons, with rail traffic surging 69%. Kazakhstan proposed a joint roadmap to modernize infrastructure and raise annual capacity to 20 million tons. Iran confirmed it has completed the process of allocating a land plot to Kazakhstan in the Shahid Rajaee port (Bandar Abbas).
Port Access and Caspian Logistics
Iran also offered Kazakhstan access to the Chabahar port, providing a gateway to South and Southeast Asian markets. In return, Kazakhstan is considering granting Iranian companies port facilities in Aktau and Kuryk on the Caspian Sea. The sides agreed to accelerate implementation of previously reached agreements.
What's Next
The two countries are to finalize a joint roadmap for infrastructure modernization in the coming months. It remains unclear how quickly the capacity target of 20 million tons can be achieved given existing infrastructure constraints.
