Blood Alliance Renewed: What the Xi-Kim Summit Means for the New Cold War in Asia

On June 8–9, 2026, Chinese President Xi Jinping traveled to Pyongyang for his first overseas trip of the year and his first visit to North Korea in seven years [1]. Kim Jong Un received him with a state welcome and, over two days of talks, declared that deepening ties with China constitutes his country's "most important top-priority strategic work" [2]. The language was remarkable—not for its warmth, which is standard in Sino-DPRK communiqués, but for what it signaled: Kim's recalibration back toward Beijing after years spent cultivating Moscow as his primary patron [3].

The summit produced pledges to expand cooperation in trade, agriculture, health, construction, science, and technology [4]. Both leaders agreed to strengthen "strategic communication" through high-level visits [5]. Kim reaffirmed full support for the "One China principle" on Taiwan [1]. What was absent from the official readouts, however, may prove more consequential than what was included.

What Was Said—and What Wasn't

Neither side's official statement referenced North Korea's nuclear weapons program, denuclearization, or security developments on the Korean Peninsula [6]. This marks a stark departure from Xi's 2019 visit to Pyongyang, when China publicly stated its commitment to advancing denuclearization efforts [7].

Patrick Cronin, chair for Asia-Pacific security at the Hudson Institute, assessed the omission bluntly: "China is more focused on denying US influence than denying North Korea nuclear weapons" [7]. Ellen Kim of the Korea Economic Institute of America went further, arguing that "Kim was seeking China's endorsement of North Korea as a nuclear weapons state, and he got it through China's silence" [7].

Andrew Yeo of the Brookings Institution noted that denuclearization is simply no longer a top priority for Beijing as it was a decade ago [7]. China's policy ambiguity on the issue began emerging in 2024, driven in part by Beijing's concern that pressing Pyongyang too hard on nuclear issues could push Kim further into Moscow's orbit [7].

The Economics of Dependency

The material foundation of the China-North Korea relationship is trade—and on this score, the asymmetry is overwhelming. China accounts for an estimated 95% of North Korea's total external trade [8]. The cumulative bilateral trade volume reached $2.74 billion in 2025, a 25% surge from the previous year and approaching pre-pandemic levels [9].

The trade data tells a story of disruption and recovery. In 2017, before the Trump-era "maximum pressure" sanctions campaign, bilateral trade stood at $5.29 billion. It crashed to $2.43 billion in 2018 as sanctions bit, recovered partially by 2019 ($2.67 billion), then collapsed to just $530 million in 2020 when North Korea sealed its borders during COVID-19 [9]. The recovery since 2022 has been steady but incomplete—2025's $2.74 billion remains roughly half the 2017 peak [9].

China's exports to North Korea totaled $1.83 billion in 2024, while imports from North Korea were just $347 million, reflecting a massive trade surplus in Beijing's favor [10]. North Korea depends on China for the bulk of its fuel supply and food imports, giving Beijing theoretical leverage over Pyongyang's decision-making [8].

But the question of whether China has ever successfully used that leverage to restrain North Korean provocations yields a thin record. A Brookings Institution analysis concluded that Beijing is "neither a reliable stabilizer nor a direct enabler" of North Korea's nuclear threat [11]. China has voted for UN sanctions in the past—most notably after North Korea's 2017 nuclear test—but enforcement has been inconsistent, and since 2019, Beijing has done little to press Pyongyang on denuclearization or to restrict its missile program [11].

The 2019 Comparison: Promises Then and Now

Xi's June 2019 visit to Pyongyang occurred against a different backdrop. The Trump-Kim summits in Singapore (2018) and Hanoi (2019) had raised the prospect of diplomatic engagement, and China positioned itself as a supporter of denuclearization talks [7]. Xi expressed willingness to "play a constructive role" in resolving tensions on the peninsula [6].

Seven years later, those commitments are unfulfilled. North Korea conducted no further nuclear tests but dramatically accelerated its missile program, launching over 100 missiles between 2022 and 2024 [12]. China's response was to shield Pyongyang at the United Nations. In March 2024, Russia vetoed the renewal of the UN Panel of Experts monitoring North Korea sanctions, and China abstained rather than oppose Moscow—effectively allowing the panel's mandate to expire [13].

The 2026 summit's cooperation pledges—in trade, agriculture, and technology—are broader in stated scope than 2019's but lack specific commitments on volumes, aid figures, or timelines. No joint statement referenced quantified economic assistance, energy subsidies, or weapons technology transfers [4][5].

Sanctions Erosion: The Dollar Value of Evasion

The formal UN sanctions regime against North Korea remains on paper, but its enforcement has eroded substantially. A November 2025 report by the U.S.-China Economic and Security Review Commission identified China as "the decisive enabler of sanctions evasion" by countries the report termed the "axis of autocracy" [14].

Specific categories of documented evasion include petroleum products, where UN Resolution 2397 caps refined petroleum exports to North Korea at 500,000 barrels annually. Ship-to-ship transfers in Chinese waters have allowed North Korea to exceed this cap repeatedly [14]. In July 2025, NK Pro found that sanctioned North Korean tankers were openly sailing in Chinese waters near known smuggling hotspots without interdiction by Chinese authorities [14].

Labor exports represent another channel. Russia reportedly issued more than 36,000 visas to North Korean nationals in 2025, most categorized as "education visas"—an arrangement that allows Pyongyang to earn foreign currency while circumventing UN sanctions banning DPRK labor exports [15].

The estimated dollar value of North Korea's sanctions-busting military trade with Russia alone is significant. Hankuk University professor Guseinova Olena estimated in October 2024 that Russia had acquired between $1.72 billion and $5.52 billion in munitions from North Korea through barter trade or mixed cash-barter arrangements [15].

In response to the collapse of the UN Panel of Experts, eleven countries—including the U.S., UK, France, Japan, and South Korea—established the Multilateral Sanctions Monitoring Team (MSMT) in October 2024 to fill the monitoring gap [13]. The MSMT has published two reports: one in May 2025 on Russia-DPRK military cooperation, and another in October 2025 on North Korean cyber activities and sanctions evasion [13].

The Russia Factor: Kim's Other Patron

The Xi-Kim summit cannot be understood in isolation from North Korea's deepening military relationship with Russia. Since 2022, Pyongyang has transferred an estimated 15 million 152mm artillery shells, 220 artillery pieces, and 148 KN-23 short-range ballistic missiles to Russian forces fighting in Ukraine [16][17]. By mid-2025, North Korean ammunition accounted for roughly half of Russian artillery shells fired in Ukraine, according to Ukrainian military intelligence [18].

North Korea has also deployed between 14,000 and 15,000 soldiers to fight alongside Russian troops since fall 2024 [16]. In exchange, the MSMT explicitly stated that Russia "provided data feedback on ballistic missiles, leading to improvements in missile guidance performance" [17]. U.S. Forces Korea Commander General Xavier Brunson warned in April 2025 that Russian technology sharing would "enable advancements of DPRK's weapons of mass destruction program across the next three to five years" [17].

This deepening Russia-DPRK relationship has complicated China's calculations. Analysts at the Foreign Policy Research Institute noted that the trilateral dynamic among Beijing, Moscow, and Pyongyang is less a formal alliance than a set of overlapping bilateral relationships with significant internal tensions [19]. North Korea has historically excelled at playing its patrons against each other—a strategy that served it well during the Cold War, when Pyongyang extracted aid from both the Soviet Union and China by threatening to lean toward the other [19].

Kim appears to be reprising that playbook. His declaration of China as his "top priority" comes after years of conspicuously prioritizing Moscow, including signing a mutual defense pact with Putin in June 2024 [20]. The message to Beijing is implicit: if you want to remain North Korea's primary partner, you need to offer more.

The Nuclear Domino Question

The consolidation of the China-North Korea partnership, combined with Beijing's apparent abandonment of denuclearization as a policy goal, has intensified debate over whether U.S. allies in Northeast Asia will pursue independent nuclear deterrents.

In South Korea, public support for acquiring indigenous nuclear weapons reached an all-time high of 76.2% in 2025, according to the Asan Institute for Policy Studies—up 5.3 percentage points from the previous year and the highest figure since the institute began tracking the question in 2010 [21]. Less than half of South Korean respondents believed the United States would use nuclear weapons to defend South Korea if North Korea launched a nuclear strike [21].

Japan presents a more complex picture. A Foreign Policy article argued in November 2025 that "it is no longer a question of if but when Japan and South Korea will acquire independent nuclear deterrents" [22]. But Japanese public opinion remains heavily opposed: a Yomiuri Shimbun/Japan Institute of International Affairs survey in early 2026 found 79% of respondents supporting the principle that Japan shall not possess nuclear weapons [23].

Both countries face significant legal and treaty constraints. South Korea is a signatory to the Nuclear Non-Proliferation Treaty (NPT) and maintains a bilateral agreement with the United States restricting enrichment and reprocessing activities. Japan's post-war constitution and its "Three Non-Nuclear Principles"—not possessing, not producing, and not permitting the introduction of nuclear weapons—add additional layers of constraint [23]. However, both nations maintain significant "nuclear latency": the technical infrastructure to develop weapons relatively quickly if the political decision were made [22].

The Steelman Case for Stability

Not all analysts view the Xi-Kim summit as destabilizing. The argument that closer China-North Korea ties reduce the risk of miscalculation rests on several premises.

First, Beijing has a direct interest in preventing conflict on its border. A war on the Korean Peninsula would produce a refugee crisis, potential nuclear contamination, and the prospect of U.S. forces on China's doorstep—all outcomes Beijing wants to avoid [11]. Closer ties give China better channels to communicate that message.

Second, a North Korea that feels more secure—backed by both Chinese economic support and Russian military cooperation—may be less likely to engage in brinkmanship. Some analysts argue that the DPRK's most provocative periods have coincided with moments of diplomatic isolation, not alignment [24].

Third, Xi's visit may serve to balance Moscow's growing influence over Pyongyang. If China can pull Kim back toward Beijing's orbit, it may restore a degree of restraint that Russia—which openly defends North Korea's nuclear status—does not provide [19]. Beijing still formally supports denuclearization, even if it no longer presses the issue publicly.

The counterargument is that China's version of "stability" means preserving the Kim regime and limiting U.S. influence, not reducing the nuclear threat. As the Brookings analysis noted, China's objectives are "fundamentally misaligned" with Washington's goals of denuclearization and alliance solidarity [11].

Taiwan and the Second-Order Effects

A more stable Kim regime, backed by Chinese economic support, has implications beyond the Korean Peninsula. The question of whether deeper Chinese commitment to North Korea frees up military resources or attention for a potential Taiwan contingency is debated among defense analysts.

The U.S. Congress has maintained bipartisan support for Taiwan's defense, with the 2026 Consolidated Appropriations Act earmarking $1 billion for the Taiwan Security Cooperation Initiative and $150 million to replace defense articles provided to Taiwan [25]. But some analysts argue that a consolidated China-North Korea-Russia alignment across Northeast Asia stretches U.S. defense planning across multiple potential flashpoints simultaneously.

Kim's explicit endorsement of the "One China principle" during the summit adds a diplomatic dimension [1]. While this is standard DPRK rhetoric, its reaffirmation in the context of elevated partnership status signals that Beijing may view North Korea as a useful card in its Taiwan strategy—not because a stable Kim regime frees up PLA resources in any direct sense, but because a tighter alliance system in Northeast Asia complicates U.S. force posture across the region.

What Comes Next

The Xi-Kim summit produced atmospherics and broad frameworks rather than specific, verifiable commitments. The concrete follow-through—whether trade volumes actually increase, whether Chinese economic assistance materializes at scale, and whether Beijing exercises any restraining influence over Pyongyang's weapons programs—will determine whether this represents a genuine strategic realignment or another round of aspirational rhetoric.

What is already clear is the shift in China's public posture. By visiting Pyongyang as his first overseas trip of 2026, by omitting any reference to denuclearization, and by accepting Kim's declaration of China as his "top priority" without demanding visible concessions, Xi has signaled that the old framework—in which Beijing maintained at least a rhetorical commitment to a denuclearized peninsula—is functionally dead [7][6].

For Seoul, Tokyo, and Washington, the policy implications are immediate. The sanctions regime is eroding. North Korea's weapons programs are advancing with Russian technical assistance. And China, the one power with genuine economic leverage over Pyongyang, has indicated it has other priorities.
