The Northern Sea Route

Along the top of Russia runs a sea lane that cuts a voyage from northern China to northern Europe by up to two weeks, if the ice allows. The Northern Sea Route follows Siberia's Arctic coast from the Kara Sea to the Bering Strait, and for most of the year it is frozen shut. In summer and autumn, as sea ice retreats, ships can pass, often escorted by the nuclear icebreakers that only Russia operates. Moscow treats the route as a national transportation corridor and a pillar of its Arctic strategy, and since sanctions isolated Russia from Western markets, China has become its main partner in using it.

Under Russian law the route runs about 5,600 kilometers from the Kara Gate at Novaya Zemlya to the Bering Strait, crossing the Kara, Laptev, East Siberian, and Chukchi Seas. Its chokepoints are shallow Arctic straits, among them the Vilkitsky Strait off Cape Chelyuskin, the northernmost point of mainland Asia, and the Sannikov and Dmitry Laptev Straits, whose depths limit the size of ships. Murmansk anchors the western end, and Sabetta, the Yamal LNG terminal, Dudinka, and Pevek serve energy and mining projects along the coast. Most cargo on the route is destinational, such as liquefied gas and oil leaving the Russian Arctic, rather than true transit between oceans. The navigation season for transits usually runs from about July to November.

Europeans sought a Northeast Passage from the 1550s, and Adolf Erik Nordenskiöld's Vega made the first full transit in 1878–79. The Soviet icebreaker Sibiryakov crossed in a single season in 1932, and Moscow built the route into a state-run Arctic artery. Rosatom, the state nuclear corporation, has managed it since 2018 and issues the permits ships need to enter. The United States and others dispute Russia's control over some of the straits, which they regard as international. Total cargo was about 37 million tonnes in 2025 by the consultancy Gekon's count, far below a government target of 80 million. Transits are growing from a small base: 103 voyages carrying about 3.2 million tonnes in 2025, and 104 voyages and some 3.7 million tonnes by September 30, 2026, according to Norway's Centre for High North Logistics, led by Chinese cargo.
