As instability in the Middle East prompts governments and businesses to seek alternative trade routes, South Korea is moving to develop Arctic shipping links through Russia’s Northern Sea Route (NSR). The push not only reflects Seoul’s growing Arctic ambitions but also underscores their potential to help Russia regain influence over trade flows between Asia and Europe through the NSR after Western sanctions and geopolitical tensions weakened the appeal of traditional Russian transit corridors.
The Korea Ocean Business Corporation (KOBC) and the Korea Shipping Association (KSA) announced on May 15th that they have preliminarily selected a Busan-based shipping company, PanStar Line, to operate South Korea’s trial voyage along Russia’s Northern Sea Route, planned for later this year.
The plan entails an ice-class container ship with a capacity of about 3,000 twenty-foot equivalent units (TEUs) sailing from Busan through the Russian Arctic, making a stop in Tromsø, Norway, before proceeding to Rotterdam in the Netherlands, and then completing a return journey via the same route.
PanStar Line was tentatively awarded the contract to carry out a pilot Arctic voyage after being the only participant in a public bidding process opened by KOBC and KSA on April 27th. The tender sought an operator for a container vessel capable of transporting approximately 3,000 TEUs. The shipping company currently runs container routes linking South Korea with Japan and China.
Funding for the demonstration voyage will come from the KSA, while the KOBC will facilitate the purchase of an ice-class vessel by providing financing on favorable terms. The voyage will additionally benefit from reduced port fees to help offset the substantial costs associated with Arctic operations.
Per the reports so far, it appears that PanStar Line has yet to secure the vessel that will be used for the voyage. Per the requirements outlined by South Korean officials, the ship must be ice-class certified with a carrying capacity of about 3,000 TEUs and in compliance with the International Maritime Organization’s Polar Code requirements for operations in Arctic waters.
Officials said the vessel acquisition and certification process are expected to take several months, so the voyage is unlikely to set sail before August and will more likely commence in September.
The South Korean government first announced plans last year for an Arctic demonstration voyage involving container cargo as part of its broader maritime strategy to position South Korea as a major Arctic logistics hub and a potential alternative to China in northern shipping corridors.
However, this planned demonstration voyage has now gained even more significance amid disruptions in the Strait of Hormuz caused by the Iran war, together with lingering security concerns in the Red Sea corridor – a key zone of operations for the Iran-backed Houthi movement based in Yemen – that have emerged in recent years.
In the first half of 2025, the Author had discussed how Ukraine’s concerted attacks on Russian oil and gas installations along international transit routes had accelerated a shift toward alternative transit routes through Central Asia, contributing to a decline in Russia’s influence in the post-Soviet space, with Turkey, Azerbaijan and Kazakhstan moving in.
Before the Russia-Ukraine conflict, more than 90% of the rail traffic between Europe and the Far East was carried along the Northern Corridor that passes through Russia however, as a result of the sanctions in 2022, shipments reduced over the Northern Corridor by 40%, while the support for the Trans-Caspian International Transport Route (TITR), commonly known as the Middle Corridor, began increasing.
There was an unprecedented surge in the traffic via the TITR in 2022, with cargo volume growing by 2.5 times to 1.5 million tonnes, and in 2023, the rail freight along this route also increased by more than 60% to 433,000 tonnes in the first quarter of 2023.
The TITR handled about 4.12 million metric tons of cargo in 2025, down 8.1% from the record 4.48 million tons transported in 2024. Despite the decline, volumes remained nearly 49% higher than in 2023, when traffic reached 2.76 million tons, and almost three times higher than the 1.49 million tons recorded in 2022, underscoring the corridor’s rapid expansion after Western sanctions and logistics disruptions redirected freight away from Russia-linked routes.
The route’s growth has been particularly striking compared with pre-war levels. Cargo traffic in 2025 was roughly seven times higher than in 2021, when volumes were below 600,000 tons, highlighting how TITR has evolved from a niche transit corridor into a major East-West trade artery.
Container traffic also continued to expand, rising to roughly 77,000 twenty-foot equivalent units (TEUs) in 2025 from about 56,500 TEUs in 2024, reflecting growing demand for containerized trade between China, Central Asia, the Caucasus and Europe.
However, the war in the Middle East may have begun to offset the aforesaid losses of Russia by once again creating a sense of urgency around the need for diversifying the logistics for global trade and commerce, only this time in the maritime domain, thereby generating interest in alternative transit routes such as Russia’s Northern Sea Route (NSR).
“Given the instability of maritime supply chains due to the situation in the Middle East, we must begin preparations for the revival of the Arctic route now, viewing it as a long-term project to provide alternative routes for the import, export, and transportation of energy resources. We expect the pilot project in 2026 to be the first step toward achieving this goal,” a KOBC representative said.
Could the Northern Sea Route Offset Russia’s Losses Along the Northern Corridor?
The NSR runs along the northern coast of Russia, affording it the ability to administer permits for most vessel transits through this route, and by extension, a potentially significant influence over maritime trade between Europe and Asia, depending upon the volume of traffic that this route is able to attract in time.
The NSR is currently navigable without major restrictions, only during a limited seasonal window between summer and autumn. For much of the year, ice conditions require vessels to be escorted by icebreakers, significantly increasing transit costs. Also, Russia currently permits only its own icebreaker fleet to provide such services.
Also, even during the navigable season, drifting ice remains a hazard to vessels, and together with a lack of robust emergency rescue infrastructure along the route, it poses significant operational risks to transit in Arctic waters.
However, similar arguments can be made about TITR and the Northern Corridor as well. The Northern Corridor still remains the most efficient route for exports to Europe from Asia, despite being longer than the TITR.
This is because the TITR is fraught with various technical and logistical difficulties. Despite being shorter in length than the Northern Corridor, it remains slower and more expensive than the latter, as it involves multimodal transfers to cross the sea and a greater number of border crossings.
Above all, the complex nature of transit and trade procedures in countries that the Middle Corridor traverses makes the border crossings unpredictable, and this, coupled with infrastructure bottlenecks in maritime, rail, and road transport throughout the entire route, renders the TITR as a very complicated and unreliable pathway.
Conversely, the Northern Corridor features a lot of developed infrastructure and offers a lengthier but uninterrupted transit.
As a result, despite its longer distance, the Northern Corridor boasts the shortest average transit times of 14 days, while the Middle Corridor’s transit times range from 13 to 21 days, with the possibility of delays extending this timeframe up to 60 days in worst-case scenarios.
And yet, in the years following the onset of the Russia-Ukraine war, while TITR expanded dramatically, the Northern Corridor’s market share has steadily eroded.
