The Middle Corridor is the only overland route from China to Europe that does not cross Russian territory. That fact alone explains all the interest of the past four years: traffic grew from 586 thousand tonnes in 2021 to 4.5 million tonnes in 2024, that is almost eightfold. In February 2026 the World Bank issued a guarantee of USD 846 million, mobilising USD 1.41 billion of commercial financing for the Kazakhstani railway. The European Union is holding a Global Gateway package of EUR 12 billion for transport infrastructure in Central Asia.
Then begins what is mentioned less often in presentations. The route transships cargo twice — at the border with China because of the different track gauge, and on the Caspian from rail to ferry. The level of the Caspian Sea is falling by about 30 centimetres a year, and this has already reduced the number of ferry sailings. There are not enough vessels: the purchase of ships is still at the feasibility stage. According to the Carnegie Endowment, the entire Middle Corridor handles about 6% of what the northern route through Russia is able to carry — which makes it not a replacement but a window of opportunity that may narrow.
For an investor there is a practical conclusion here, and it is not about “getting into transit”. The money on this route today is earned not so much by carrying cargo as by clearing its bottlenecks: vessels, terminals, the container fleet, cargo handling, document flow. Below is where exactly, and with what qualifications.
