A fortress on rails, carrying a leader back into the world
After more than four years of self-imposed isolation, North Korea's Kim Jong Un is preparing to cross his country's borders once more — not toward reconciliation or denuclearization, but toward a quieter and more transactional kind of diplomacy. His armored train, rolling toward Vladivostok to meet Vladimir Putin, carries with it the weight of two sanctioned nations finding common cause in each other's necessity. What was once a story of cautious diplomatic opening now bends toward a different arc: the consolidation of an axis defined not by shared values, but by shared pressure.
- After four years of pandemic-era silence, Kim Jong Un's first foreign trip signals that North Korea is ready to re-engage — but on terms shaped by war, not peace.
- Russia's grinding campaign in Ukraine has created a weapons deficit that North Korea, with its vast munitions stockpiles, is uniquely positioned to fill — making this summit less a diplomatic courtesy than a supply negotiation.
- The choice of armored train over aircraft is itself a message: a deliberate, unhurried assertion of control and security consciousness, echoing a dynasty's deep-seated fear of vulnerability in transit.
- The meeting risks accelerating international alarm, as a formalized military partnership between Moscow and Pyongyang could strain sanctions regimes and alter the material calculus of the Ukraine conflict.
- What was once a diplomatic whirlwind — Singapore, Hanoi, Panmunjom — has narrowed to a single corridor: the rail line between two isolated powers drawing closer as the world watches.
Kim Jong Un was preparing to board his armored train — more than twenty green-painted cars — for a journey across the Russian Far East to Vladivostok. The trip, expected in September 2023, had not been officially announced, but its purpose was widely understood: a meeting with Vladimir Putin to discuss the supply of North Korean weapons to Russia's war in Ukraine.
The train was more than transport. Fitted with communications equipment and space for senior advisors, it functioned as a mobile command center — a reflection of the security culture that has long defined North Korean leadership. Kim's father, Kim Jong Il, famously refused to fly at all. The younger Kim has proven more willing to board aircraft, but for this journey he chose the rails — a choice shadowed, perhaps, by the memory of a massive explosion that struck a station near the Chinese border just after his father's train had passed through in 2004, killing over a hundred people.
Kim had actually traveled more than his father during his years in power. Between 2018 and 2019, he crossed borders repeatedly: by train to Beijing to meet Xi Jinping, on foot across the DMZ to meet South Korea's president, by jet to Singapore for a historic summit with Donald Trump, and by rail through China to a second Trump meeting in Hanoi that ultimately collapsed. In April 2019, he made his first visit to Vladivostok to meet Putin. Then came the pandemic, and silence.
Now, four years later, the silence was ending — but the context had transformed entirely. Russia needed ammunition for a war of attrition. North Korea had stockpiles and incentives. The armored train rolling toward the border was not a symbol of renewed openness, but of something more calculated: two internationally isolated states finding in each other a partner that the rest of the world was unwilling to be.
Kim Jong Un was preparing to board an armoured train bound for Russia's far eastern port of Vladivostok, a journey that would mark his first venture beyond North Korea's borders in more than four years. The trip, expected in September 2023, had not been officially announced, but the destination and timing pointed toward a single purpose: a meeting with Vladimir Putin, likely to discuss the supply of North Korean weapons to Russia's war in Ukraine.
The train itself was a marvel of paranoia and engineering. More than twenty armoured cars, painted in the leader's signature green, would carry Kim across the border and through the Russian Far East. The journey would consume nearly a full day to cover the thousand-plus kilometres, a duration that reflected both the distance and the deliberate pace of North Korea's aging rail infrastructure. Inside the train, Kim's personal cabin was fitted with white interior walls, communications equipment, and space for meetings with his closest advisors. This was not a casual mode of transport but a mobile command centre, a statement of security and control made manifest in steel and careful design.
Kim's preference for train travel over air had become something of a signature. His father, Kim Jong Il, had famously avoided flying altogether, but the younger leader had proven willing to take to the skies when circumstances demanded it. He owned a Russian-made Ilyushin jet, which he had deployed for several of his diplomatic missions. Yet for the journey to Russia, he had chosen the train—a choice that spoke to the weight of the moment and perhaps to the lessons of history. In 2004, a massive explosion had torn through a rail station near the Chinese border just after Kim Jong Il's train had passed through, killing more than a hundred people. The cause was never determined, nor was it ever confirmed whether the blast had been an assassination attempt. The memory lingered.
Since taking power in 2011, Kim had actually travelled abroad more frequently than his father had. His first foreign trip as leader came in March 2018, when he took that green train to Beijing to meet Xi Jinping, China's paramount leader and North Korea's most crucial ally. The following month, in April, he made history by crossing the demilitarized zone on foot at Panmunjom to meet South Korean President Moon Jae-in—the first time any North Korean leader had set foot in the South. By May, he was flying his Ilyushin to Dalian for another summit with Xi. In June, he boarded an Air China Boeing 747 for a direct flight to Singapore, where he sat down with Donald Trump in what was billed as a historic first summit between a sitting American president and a North Korean leader. The two sides issued a joint statement promising new relations and North Korean denuclearization, though the promise would prove hollow.
The diplomatic calendar of 2018 and 2019 had been a whirlwind. Kim returned to China by jet in June 2018, toured industrial facilities and agricultural research centres, and discussed denuclearization with Xi. In January 2019, he took the train back to Beijing for a fourth visit. In February, he spent three days on the rails crossing China en route to Hanoi for a second summit with Trump. That meeting collapsed after two days, the two sides unable to agree on sanctions relief and the mechanics of nuclear disarmament. In April 2019, Kim had made his first trip to Vladivostok, taking the train across the Tumen River into Russia to meet Putin. In June, he crossed the inter-Korean border again for talks with Trump.
Then came silence. For more than four years, Kim had not left North Korea. The pandemic had shuttered borders and isolated the regime further. But now, in 2023, the calculus had shifted. Russia needed weapons for its grinding war in Ukraine. North Korea had weapons to sell. The armoured train was being prepared. The meeting with Putin would happen, and when it did, it would signal not merely a resumption of Kim's foreign diplomacy but a fundamental realignment—North Korea stepping openly into Russia's orbit at a moment when both nations faced international isolation and both had reasons to bind themselves closer together.

Why does Kim Jong Un insist on taking a train when he has access to a jet? It seems inefficient.
It's not really about efficiency. The train is a fortress on rails. He controls every metre of track, every station, every moment. A plane puts him in the air, dependent on pilots and mechanics and the whims of airspace. The train is his domain.
But his father died in an explosion near a train station. Wouldn't that make him wary of rail travel?
You'd think so. But the explosion happened to his father, not to him. And the cause was never proven. For Kim Jong Un, the train represents continuity with his father's methods, even if those methods were dangerous. It's a statement: I am in control here.
What does this September trip to Russia actually mean?
It means North Korea is betting on Russia. It means weapons sales, military cooperation, a formal alliance at a moment when both countries are isolated. It's Kim stepping out of the shadows after four years and saying: we are not alone.
Could this meeting reshape the Ukraine war?
Not directly. But if North Korean weapons start flowing to Russia in volume, it extends Russia's capacity to fight. It also signals to the world that sanctions regimes are porous, that isolated states can find each other and survive together.
Is this risky for Kim?
Everything he does is risky. But staying isolated is also risky. This is a calculated gamble that Russia's partnership is worth the exposure.
