China Grows Wary as Putin-Kim Alliance Deepens

BEIJING / PYONGYANG — China is growing increasingly uneasy with the deepening military partnership between Russia and North Korea, according to reporting by RBC-Ukraine, raising questions about how far Beijing is willing to let Moscow pull one of its closest neighbors into a war-footing relationship that China did not design and cannot fully control.

The wariness comes as the Kim-Putin axis produces tangible military outputs: North Korea’s state media outlet KCNA confirmed this week that Pyongyang conducted live-fire drills involving artillery and ballistic missiles, a demonstration of capability that analysts said reinforces the military utility North Korea now claims within its partnership with Moscow. A BBC investigation published this week found that a fresh wave of North Korean soldiers may be on the way to Russia to join fighting in Ukraine.

For Beijing, the picture emerging from Moscow-Pyongyang coordination is not one it orchestrated — and that distinction matters.

What Beijing Wanted, and What It Got

China’s preferred posture in the Russia-Ukraine war has been studied neutrality: close enough to Moscow to benefit from cheap Russian energy and a weakened Western rival, distant enough to protect trade relationships with Europe and avoid secondary sanctions. That balance requires Beijing to be seen as a potential stabilizer, not as a co-belligerent.

The Russia-North Korea axis complicates that image in two ways. First, North Korean troops fighting in Ukraine under Russian command — a deployment already documented in 2025 — makes the conflict a multilateral affair in ways that draw harder Western scrutiny of anyone Moscow counts as aligned. Second, and more directly relevant to Chinese interests, a confident, combat-hardened, Russia-backed North Korea on China’s northeastern border is not obviously in Beijing’s strategic interest.

Pyongyang has historically served as a buffer state that China manages carefully — pressuring just enough to prevent nuclear provocation, supporting just enough to prevent collapse. A North Korea that is receiving advanced Russian military technology, battlefield experience, and what appears to be significant economic support from Moscow is a North Korea less dependent on Beijing for its survival. That shifts leverage.

The Drills Signal

KCNA’s announcement of live-fire exercises involving both artillery and missiles came without the advance diplomatic signaling Pyongyang sometimes uses to calibrate regional tension. The drills serve multiple audiences: they demonstrate operational readiness that Russia can point to as proof its North Korean partner contributes real military value, and they remind South Korea, Japan, and the United States that Pyongyang’s force posture has continued to develop regardless of the war in Europe.

For Beijing, the timing matters. Live-fire exercises by a neighbor increase pressure on China to take a public position — either toward quiet endorsement, which risks Western blowback, or toward mild criticism, which risks friction with Pyongyang and, by extension, Moscow.

The Troop Question

The BBC’s reporting on a potential new deployment of North Korean soldiers to Russia reflects a structural dynamic: if the original troop commitment produced results — battlefield experience, weapons testing under combat conditions, economic transfers from Moscow — Pyongyang has every incentive to continue and expand it. That logic does not require Beijing’s approval, and apparently did not receive it.

North Korean troops fighting in an active war in Ukraine create a precedent that China cannot easily reverse. Personnel rotation at scale means training pipelines, logistics channels, and intelligence-sharing arrangements that institutionalize the Russia-North Korea relationship over time. Each rotation makes the next one easier.

Beijing’s Narrow Options

China has limited tools to restrain the partnership without publicly breaking with either Moscow or Pyongyang. Economic leverage over North Korea remains real but has diminished as Russian transfers substitute for Chinese trade. Diplomatic pressure risks looking like alignment with Western efforts to isolate Russia — exactly the optic Beijing has spent three years avoiding.

The result is the posture RBC-Ukraine’s reporting describes: wariness, not action. Beijing watches a security architecture on its northeastern flank shift in ways it did not plan and may not be able to reverse, while managing the public appearance of a regional power still in control of its neighborhood.

What to Watch

Three indicators will signal whether Chinese discomfort escalates into something more consequential: whether Beijing reduces diplomatic cover for Pyongyang at the United Nations Security Council; whether Chinese state media begins edging toward more critical framing of the Putin-Kim relationship; and whether Chinese economic engagement with North Korea — currently suppressed but not eliminated — is adjusted as a signal to Moscow.

None of those shifts appear imminent. But the gap between what China wanted from the Russia-Ukraine war and what the Russia-North Korea alliance is producing is now wide enough that analysts and foreign governments are noting it.

The war’s political stalemate and the continued exchange of strikes in Ukraine show no sign of resolving in ways that would naturally wind down the Moscow-Pyongyang partnership. As long as Russia needs manpower and Pyongyang needs revenue and technology, the bilateral arrangement has structural incentives that operate independently of what Beijing prefers.
