The Arctic has spent most of human history as a strategic afterthought. Too cold, too remote, too hostile for sustained military presence or economic exploitation. The handful of nations with Arctic territory — Russia, Canada, the United States, Norway, Denmark, Sweden, Finland, and Iceland — managed their competing claims through the Arctic Council, a cooperative forum established in 1996 that operated on the assumption that the region was better managed as a shared commons than contested as a battleground.
That era is ending.
Climate change is transforming the Arctic at three times the global average warming rate. Sea ice that once persisted year-round is now seasonal. The Northwest Passage — a route through the Canadian Arctic that connects the Atlantic and Pacific Oceans — is navigable for increasing stretches of the year. The Northern Sea Route along Russia’s Arctic coast, which required icebreaker escorts for most of the 20th century, has become a commercially viable shipping corridor. Beneath the ice, estimates suggest the Arctic holds approximately 13% of the world’s undiscovered oil reserves and 30% of its undiscovered natural gas — along with significant deposits of rare earth minerals, lithium, and other materials critical to the green energy transition.
A region that was uninviting is becoming valuable. A region that was peripheral is becoming central. And the great powers — including one that has no territorial claim to the Arctic at all — are positioning for what comes next.
Russia’s Arctic Ambitions
No country has invested more deliberately in Arctic power than Russia.
Russia’s Arctic coastline stretches 24,000 kilometres — longer than any other nation’s. The Arctic generates approximately 20% of Russia’s GDP and accounts for 80% of its natural gas production. Russia has spent the last fifteen years rebuilding military infrastructure across its Arctic territory that was abandoned after the Soviet collapse: airfields, radar stations, missile batteries, submarine bases, and icebreaker fleets.
Russia now operates the world’s largest icebreaker fleet by an enormous margin — including the only nuclear-powered icebreakers in service. These vessels are not merely logistical assets. In a region where naval operations are constrained by ice, the ability to operate year-round is a decisive military advantage. Russia has also reopened and massively upgraded the Soviet-era bases on Franz Josef Land, Novaya Zemlya, and the New Siberian Islands — placing air defense and anti-ship missile systems at positions that cover the entire Northern Sea Route and the approaches to the Barents Sea.
The strategic logic is clear. Russia’s Northern Fleet — headquartered at Severomorsk near Murmansk — is home to the majority of Russia’s nuclear-armed submarines. The Arctic waters between Norway and the Russian coast, known to NATO planners as the GIUK Gap (Greenland-Iceland-United Kingdom), are the route through which Russian submarines must pass to access the North Atlantic. Control of Arctic sea lanes and airspace is not primarily about shipping routes or oil rights. It is about the strategic reach of Russia’s nuclear deterrent.
NATO’s Scramble North
Russia’s Arctic build-up accelerated NATO’s own reassessment of its northern flank — a process that the war in Ukraine dramatically accelerated.
Finland and Sweden, historically neutral nations that had carefully avoided military alliance to preserve their relationships with Russia, applied for NATO membership in 2022 and joined in 2023 and 2024 respectively. The strategic consequences for the Arctic were immediate. Finland’s membership closed the gap between NATO’s northern flank and Russia’s Arctic infrastructure. Sweden’s membership strengthened NATO’s Baltic and North Atlantic positioning. The Arctic is now a NATO lake in a way it has never been before.
Norway, a founding NATO member, has dramatically increased defense spending and military exercises in its Arctic north. The United States has expanded its presence at Thule Air Base in Greenland and has been in protracted negotiations over expanded basing rights in Greenland’s territory — a conversation that has been politically complicated by the Greenlandic independence movement and Danish sovereignty concerns.
The fundamental NATO challenge in the Arctic is technological. Much of NATO’s military hardware was designed for Central European or Middle Eastern environments and does not perform well in Arctic conditions. Cold weather operations require specialized equipment, trained personnel, and supply chains that most NATO militaries have allowed to atrophy since the Cold War. Rebuilding those capabilities — and doing so faster than Russia’s head start is consolidated — is an urgent and expensive project.
China’s Arctic Ambitions: The Non-Arctic Power
Perhaps the most significant development in Arctic geopolitics is one that does not involve any of the eight Arctic states.
China declared itself a “Near-Arctic state” in its 2018 Arctic Policy White Paper — a designation that has no basis in international law but reflects China’s intent to be treated as a stakeholder in the region’s future. China’s interest in the Arctic is multidimensional.
Economically, China sees the Northern Sea Route as a potential alternative to the Strait of Malacca and the Suez Canal — the current chokepoints of its trade routes to Europe and North America. A reliable Arctic shipping route would reduce China’s dependence on sea lanes it cannot currently control. Chinese state-owned shipping companies have invested in Arctic ports and shipping infrastructure in Russia, including the Yamal LNG project.
In terms of resources, China has positioned itself as a potential investor in Arctic mineral and energy extraction. Chinese companies have pursued interests in Greenlandic rare earth mining, Norwegian deep-sea deposits, and Icelandic fisheries. Greenland’s rare earth deposits are particularly significant — they include some of the world’s largest reserves of neodymium, dysprosium, and other elements essential for electric motors, wind turbines, and military electronics.
Scientifically, China has established research stations in Iceland and Svalbard, operates icebreaking research vessels, and has substantially increased its Arctic research funding. Scientific presence serves dual purposes: it generates genuine knowledge and it establishes the habit of being there.
Militarily, China and Russia have conducted joint naval exercises in the Arctic and the Barents Sea. The depth of military cooperation between Beijing and Moscow in the Arctic is not fully visible, but the trajectory concerns Western planners. A Sino-Russian Arctic partnership — combining Russia’s geographic position and military infrastructure with China’s capital and technological capacity — would be a qualitatively different strategic challenge than either power alone.
The Legal Battlefield
Beneath the military and economic competition lies a legal dispute that international law has not cleanly resolved.
The UN Convention on the Law of the Sea (UNCLOS) provides the primary framework for maritime boundaries and resource rights. Under UNCLOS, a country’s exclusive economic zone extends 200 nautical miles from its coast, with the possibility of extended continental shelf claims beyond that. The Arctic Ocean’s central basin — the “High Seas” area beyond all national EEZs — is, in principle, a global commons.
Multiple countries have submitted overlapping continental shelf claims to the UN Commission on the Limits of the Continental Shelf. Russia, Canada, and Denmark (on behalf of Greenland) all claim portions of the same underwater ridge system — the Lomonosov Ridge — as extensions of their continental shelves. The Commission’s process is slow, non-binding, and ultimately political in its resolution.
Russia has been the most aggressive in asserting its claims, including a famous 2007 stunt in which a Russian submarine planted a titanium flag on the seabed at the North Pole — a theatrical gesture with no legal standing but considerable symbolic force.
What the Melting Ice Really Means
The Arctic geopolitical contest is ultimately inseparable from the climate dynamics that are making it relevant.
The same process that is opening shipping routes and exposing mineral deposits is also releasing carbon stored in permafrost, disrupting weather patterns across the Northern Hemisphere, and threatening the livelihoods and cultural survival of indigenous Arctic communities who have lived in the region for millennia and whose interests are consistently afterthoughts in the great power competition.
There is a deep irony in the scramble for Arctic resources. The oil and gas beneath the Arctic seabed — if extracted and burned — would themselves accelerate the warming that made them accessible. The great powers racing to exploit the Arctic are, in a literal sense, racing to dig up the fuel for their own crisis.
Whether that irony translates into restraint is a different question. Historical precedent suggests it does not.
The Arctic is becoming the world’s next contested frontier precisely because it sits at the intersection of climate change, resource competition, military strategy, and the question of which legal frameworks actually govern the edges of the international order when the major powers disagree. Each of those dynamics is explosive on its own. Together, in a region warming faster than anywhere else on Earth, they constitute one of the most complex geopolitical challenges of the coming decades.
