China, Kazakhstan and Russia are exploring the possibility of creating a transport corridor along the Irtysh and Ob rivers. The new waterway could connect China’s western regions with the Arctic, according to the South China Morning Post.
The route would run from Xinjiang through Kazakhstan and Russia before reaching the Arctic Ocean.
Why China needs the Irtysh
According to observers, the river corridor could reduce China’s dependence on the Strait of Malacca and the Bering Strait, both of which could become strategic chokepoints. In the event of an international conflict, these routes could potentially be blocked by the U.S. or its allies.
Interest in an alternative route has increased amid geopolitical tensions, the war in Ukraine, the crisis in the Strait of Hormuz and an increased U.S. military presence in the Arctic. As Zhao Long, a senior fellow at the Shanghai Institute for International Studies, noted, «any potential solution offering additional routes will inevitably gain momentum.»
Russia is considering the Ob-Irtysh river system as part of its Trans-Arctic Transport Corridor, which could serve as an alternative to Western routes affected by sanctions. Kazakhstan, for its part, has long sought to develop shipping along the Irtysh.
Billions of dollars in investment needed
Creating a full-fledged transport corridor along the river system would be complicated by several factors. First, the Irtysh can remain frozen for up to six months a year. Second, parts of the river have become shallower because of sedimentt accumulation, requiring extensive dredging to accommodate commercial shipping.
Another challenge would be building the infrastructure needed to connect the Irtysh with China’s densely populated eastern regions. According to Artyom Lukin, a professor at Russia’s Far Eastern Federal University, the project would require tens or even hundreds of billions of dollars — resources that, at present, only China could realistically provide.
China is already expanding its Arctic shipping
Beijing is already expanding shipping along the Northern Sea Route. In August 2026, Chinese shipping company Sea Legend Shipping began regular weekly container services along the route. Russia’s Rosatom has issued transit permits for seven small and medium-sized vessels. In total, eight voyages are scheduled for the navigation season.
In 2025, the first experimental transit along the Northern Sea Route took 20 days, compared with 37 days via the Suez Canal. The Northern Sea Route is the shortest maritime route between European Russia and the Russian Far East, running through the Arctic Ocean.
