A Rare Opening: Two Superpowers, Ten Days

Pyongyang hosted two major world leaders in the space of ten days in summer 2024 — something North Korea had not done in decades. Xi Jinping, China's leader, arrived on June 8–9, 2024, marking his first visit to North Korea in nearly seven years. Vladimir Putin, Russia's president, followed on June 18–19, his first trip to Pyongyang in 24 years. The back-to-back visits are not routine diplomatic courtesy. They signal that both China and Russia are reshaping how they work with North Korea — and that North Korea is playing a larger role in their strategic plans.

Why Xi Came First: China's Long Game

Xi's last visit to Pyongyang was in 2019, five years earlier. The gap was not accidental. It coincided with stalled nuclear talks between North Korea and the United States, North Korea's border closures during the COVID pandemic, and China's own shift in how it handles the Korean Peninsula as U.S.-China competition grew more intense.

By June 2024, the landscape had changed. NATO had begun linking threats in Asia to threats in Europe. The U.S., South Korea, and Japan had tightened their security partnerships. China saw an opening: a North Korea pulled closer to Beijing would be an asset in this competition. A North Korea drifting toward Russia without Chinese involvement would be a problem.

The order of these visits matters diplomatically. Xi arrived first. This is not meaningless protocol. China remains North Korea's lifeline — its largest source of food, fuel, and economic support. China also selectively enforces international sanctions against the North. In the hierarchy of Pyongyang's relationships, Beijing is still at the top. By visiting first, Xi was sending a message: China is the primary relationship here.

Putin's Visit: A Mutual Defense Pact

Putin's visit produced something concrete: Russia and North Korea signed a mutual defence agreement. Think of this as a security promise: if either country is attacked by another nation, the other has committed to come to its aid. The agreement echoes Cold War-era alliance treaties between the Soviet Union and its partners.

For Russia, the logic is straightforward: North Korea manufactures ammunition and missiles at scale. Russia is using enormous quantities of conventional munitions in its war in Ukraine. Few countries can supply this much weaponry quickly. North Korea can. For North Korea, the benefit is less immediate but possibly longer-lasting: access to Russian military technology, a partner that is not China (which gives Pyongyang some independence), and a security guarantee from a permanent member of the UN Security Council — the very body that has punished North Korea with sanctions.

This is a familiar pattern in international relations. Smaller countries have historically gained leverage by being useful to multiple larger powers at once. Pakistan did this during the Cold War by managing relationships with both the United States and China. North Korea is attempting something similar now — except that North Korea also has nuclear weapons, which makes it harder for any of its partners to control it completely.

China's Quiet Concern

Publicly, China says little about the Russia–North Korea pact. Behind closed doors, Beijing is likely uneasy. China benefits when rules are broken by others — it weakens the international order that constrains it. But it loses if North Korean weapons flowing to Russia cause the West to send more arms to Ukraine, hardening the divide between blocs. That is exactly the division China tries to avoid in its diplomacy.

A North Korea that leans too heavily toward Russia is also a North Korea that China cannot manage as easily. The Korean Peninsula, in Chinese strategy, is a buffer zone — a space that must remain within China's sphere of influence. That is why Xi's June visit included reassurance: to remind Kim Jong Un that Beijing is still the most important partner, and to signal to the world that China has not lost control of the peninsula to Moscow.

What commitments, if any, Xi secured from Kim — economic support, technology sharing, or additional security promises — remains undisclosed.

The Emerging Alignment: Loose Knit, Mutually Useful

The summer 2024 diplomacy did not produce a formal alliance like the Warsaw Pact was during the Cold War. Instead, it created overlapping bilateral relationships. North Korea and Russia help each other. Russia and China help each other. China and North Korea help each other. All three share a common complaint: the U.S.-led security system in Asia and Europe. None has publicly declared itself part of a unified bloc, and all benefit from that ambiguity.

But there are real consequences for other countries. South Korea, Japan, and the United States now face a Korean Peninsula that is directly connected to the Ukraine war in ways it has not been since the original Korean War. South Korea had avoided sending weapons to Ukraine; in late 2024, evidence of North Korean troops fighting in Russia prompted Seoul to reconsider. The United Nations Security Council, where Russia has veto power, is essentially unable to impose new sanctions on North Korea — the primary tool the West has used since 2006 to pressure Pyongyang. A system that took years to build through consensus is now unworkable.

What Happens Next

The Russia–North Korea relationship will survive only if both sides deliver on their promises. The real turning point would come if Russia shares advanced missile or nuclear technology with North Korea — something that would materially improve Pyongyang's ability to build long-range nuclear weapons. That would force harder choices from both China and the United States.

For now, Xi's return after seven years and Putin's return after 24 years tell us something clear: both powers thought the moment justified the trip. What they said behind closed doors, what they promised, and what Pyongyang asked for in return will shape the next chapter of Korean Peninsula security — a peninsula that has been locked in place since 1953 but is now, unmistakably, shifting.
