The MSMT Report on North Korea Sanctions Implementation and the Dispute over the Monitoring Regime’s Legitimacy: Structural Implications and Policy Responses

Executive Summary

After the UN Panel of Experts was dissolved due to a Russian veto, the newly launched Multinational Sanctions Monitoring Team (MSMT) released a report on North Korean overseas workers. In response, North Korea opted not to dispute the facts but to challenge the legitimacy of the monitoring body itself. This strategy mirrors the rhetoric Russia employed in response to the IAEA, demonstrating that the structural condition of a permanent Security Council member’s veto is eroding the legitimacy of the entire North Korea monitoring framework. The case of North Korean laborers being deployed to Russian drone production lines under the guise of student visas proves that European and Asia-Pacific security are tangibly linked at the level of defense industry supply chains, and it has the potential to become a concrete agenda item for NATO-IP4 cooperation. However, as long as China, the largest host country for these workers, remains outside the MSMT, the effectiveness of implementation will be limited. This situation calls for an indirect approach through separate channels, such as the U.S.-China summit. Rather than seeking to win the legitimacy debate, South Korea should prioritize its response toward narrowing the implementation gap by upgrading its working-level participation in the MSMT, specifying intelligence sharing with NATO-IP4, and operating a parallel channel for engaging China.

I. Analysis of the Current Situation

The MSMT Report on North Korea Sanctions Implementation and North Korea’s Strong Backlash: An Analysis of the Current Situation

1. Background and Developments

The gap in the North Korea sanctions monitoring regime began in April 2024 with Russia’s exercise of its veto power. When Russia vetoed the mandate renewal for the UN Security Council’s Panel of Experts on North Korea sanctions, the multilateral monitoring system that had been in place for 15 years was dissolved [3]. To fill this void, 11 countries, including the United States, formed the Multinational Sanctions Monitoring Team (MSMT) [7]. The MSMT is not a body under the UN Security Council. As a minilateral group led by Western countries, it has faced questions about its legitimacy from its inception.

During this gap, the close ties between North Korea and Russia have elevated to a structural relationship. In June 2024, the two countries signed a Treaty on Comprehensive Strategic Partnership [3]. Subsequently, North Korea provided troops and munitions to Russia, and Russia responded in kind by acquiescing to the import of prohibited items or allowing the export of petroleum products exceeding the cap [3]. The expansion of logistics routes, exemplified by the opening of the Tumangang Bridge, shows that this cooperation has a structural foundation to continue even after the war [3]. Evidence of sensitive technology transfers, such as reactors for nuclear-powered submarines and air defense systems, also accumulated during this period [5].

The dispatch of North Korean overseas workers has entered a new phase within this structure. The UN Security Council completely banned the overseas dispatch of North Korean workers starting in 2019. This was based on the assessment that the foreign currency earned by these workers was funding North Korea's nuclear and missile programs [9]. However, after the monitoring system was neutralized, the scale of these dispatches has actually expanded. A key finding of the recent MSMT report is the sharp increase in workers dispatched to Russia [1].

2. Current Situation

On September 16, the MSMT released its report, "The Dispatch of Overseas Workers by the DPRK" [1]. The report estimated the number of North Korean overseas workers to be between 35,600 and 101,280. It stated that they are active in at least 17 countries, concentrated mainly in China and Russia [4]. The amount of foreign currency earned in a single year was estimated at $450 million to $800 million [4][9]. The report assesses that this money funds North Korea’s nuclear weapons and ballistic missile programs and urged all countries to immediately implement UN resolutions, repatriate North Korean workers, and refuse to issue new work permits [4].

The most notable part of the report concerns North Korean workers deployed to Russian drone factories. Yonhap News reported that some of them are working on Russian military drone production lines in violation of UN resolutions [6]. The Kyiv Independent reported more specifically on the MSMT's findings that Russia is bringing in North Korean workers on student visas to employ them in drone production [7]. The use of fraudulent means, such as manipulating visa types, suggests that this goes beyond simple labor dispatch and indicates that North Korean labor has been structurally integrated into Russia’s defense industry supply chain.

North Korea's reaction was immediate. A statement from a Foreign Ministry spokesperson, released through the Korean Central News Agency (KCNA), labeled the MSMT a "conspiracy group." The statement claimed, "The so-called 'Multinational Sanctions Monitoring Team' led by the U.S. has clearly revealed its identity as a conspiracy group that distorts the normal into the abnormal and frames the legal as illegal by fabricating and publishing a 'report' that takes issue with the mutually beneficial and routine economic cooperation between the Democratic People's Republic of Korea and other countries" [8]. The Foreign Ministry framed the issue not as a matter of sanctions violations but as one of "openly ignoring the principles of international law, with respect for sovereignty and non-interference in internal affairs at their core" [8]. The Daily Maverick interpreted this as a backlash against "new sanctions," which reflects North Korea's intent to define the MSMT report itself not as a verification of UN resolution implementation but as a separate sanctions measure [4].

Around the same time, North Korea continued similar legitimacy attacks against other monitoring bodies. When the IAEA released a report identifying a new uranium enrichment facility at Yongbyon, Russia dismissed it, claiming a lack of evidence on the grounds that the IAEA has no on-site access in North Korea [10][16]. Kim Yo Jong also rejected UN resolutions related to the IAEA and reaffirmed the policy of maintaining nuclear forces [14]. In a separate statement, a spokesperson for the Ministry of National Defence condemned the establishment of a ROK-U.S. information-sharing system for responding to weapons of mass destruction as a "military confrontation scheme" [11]. North Korea's logic for rejecting the MSMT, the IAEA, and the ROK-U.S. information-sharing system consistently involves denying the legitimacy of the monitoring and implementation bodies themselves.

3. Key Actors and Positions

MSMT (11 countries)was formed with the goal of replacing the monitoring functions left vacant after the dissolution of the UN Panel of Experts [7]. It is a U.S.-led structure [7]. By calling on countries to repatriate North Korean workers and deny new work permits upon releasing its report, the MSMT has taken on the practical function of trying to restore the enforcement power of Security Council resolutions [4]. However, as it is not a Security Council body, it is not immune to debates over the international legal basis of its authority to verify resolution violations.

North Koreais responding with a two-pronged approach. The Foreign Ministry has shifted the focus to the legitimacy of the monitoring body itself, framing the MSMT report as a violation of sovereignty and interference in internal affairs [8]. At the same time, it has maintained its refusal to acknowledge any violation by redefining the labor dispatch as a "mutually beneficial and routine economic cooperative relationship" [8]. This can be read as a strategy to avoid a factual dispute over sanctions implementation and instead shift the debate to the legal standing of the monitoring regime.

Russiaoccupies a dual position in this structure. On one hand, it has become a direct beneficiary by incorporating North Korean labor into its drone factories and defense production lines [6][7]. On the other hand, it uses its position as a permanent member of the Security Council to undermine the legitimacy of monitoring bodies like the IAEA by claiming their findings lack evidence [10]. It plays a dual role as both the cause of the UN monitoring system's neutralization and an enabler of legitimacy attacks on the alternative monitoring system.

Chinawas identified in the report as the largest host country for North Korean workers [4][9]. However, no separate reaction from the Chinese government or state-run media has been confirmed. Given that there are no reports of China directly incorporating this labor into its defense industry like Russia, its acceptance of these workers is presumed to be largely commercial in nature. However, as the largest host country, its absence from the 11-nation MSMT and its non-cooperation with monitoring efforts remain a fundamental constraint on the effectiveness of the monitoring network.

United Statesthrough the USTR, is conducting separate multilateral training with about 50 trading partners on the implementation of bans on imports produced with forced labor [2]. This represents a parallel pressure track through trade regulations, distinct from the MSMT's call for implementing Security Council resolutions. It can be seen as an approach to address the North Korean worker issue on two legal tracks simultaneously: violation of Security Council resolutions and the prohibition of forced labor imports.

4. Key Issues

The first issue is the legitimacy of the monitoring body. By labeling the MSMT a "conspiracy group" not mandated by the UN Security Council [8], North Korea is decoupling the report's fact-finding function from the legal basis of its monitoring authority in order to attack the latter. Whether a minilateral group can exercise the authority of Security Council resolutions in the absence of the UN Panel of Experts is an unsettled area of international law.

The second issue is the integration of North Korean labor into Russia's defense industry. The evidence of workers being mobilized for drone factories using student visas [7] shows that the dispatch of North Korean labor has transformed from a simple means of earning foreign currency into a structure that directly supports Russia's weapons production capacity. This is a case that demonstrates the tangible connection of European security (Russia's capacity to wage war against Ukraine) and Indo-Pacific security (the source of funding for North Korea's nuclear and missile programs) through a single supply chain.

The third issue is the position of China, the largest host country. As long as China remains outside the MSMT and does not cooperate with monitoring, the implementation recommendations of the report can only be partially effective. Whether this issue is addressed on the agenda of a future U.S.-China summit will be an indicator of the actual direction of sanctions implementation.

II. In-Depth Analysis of the Issue

The MSMT Report on North Korea Sanctions Implementation and North Korea’s Strong Backlash: An In-Depth Analysis

1. Analysis of Root Causes

The starting point of this conflict is the change in the monitoring body. Until April 2024, the body monitoring the implementation of North Korea sanctions was the UN Security Council's Panel of Experts. This panel was a body established by a Security Council resolution. This means it was an official body approved by the 15 members of the Council, including the permanent members. The situation changed when Russia vetoed the extension of this panel's mandate [3]. The UN-level monitoring system that had existed for 15 years was dissolved [3].

The MSMT filled this void. It is a group formed by 11 countries, including the United States [7]. It is not a body created by a Security Council resolution. It is a minilateral group formed voluntarily by the participating countries. This is the legitimacy gap that North Korea is exploiting. In its statement, the North Korean Foreign Ministry labeled the MSMT a "conspiracy group" [8]. It claimed that "the so-called 'Multinational Sanctions Monitoring Team' led by the U.S. fabricated and published a 'report' that takes issue with the mutually beneficial and routine economic cooperation between the Democratic People's Republic of Korea and other countries" [8]. What North Korea is targeting with this language is not the factual content of the report, but the authority of the body that produced it.

North Korea's logical structure is clear. Its argument is that since Russia, a permanent member of the Security Council, vetoed the continuation of the monitoring body, no subsequent monitoring system can inherit the authority of UN resolutions. The framing of the MSMT report as "new sanctions" follows the same logic [4]. It is an attempt not to dispute violations of existing UN resolutions, but to nullify the monitoring body itself by portraying it as an act of creating new norms. This is echoed in a separate statement released by a spokesperson for the Ministry of National Defence. Labeling the establishment of a U.S.-South Korea information-sharing system a "military confrontation scheme" [11] is the same rhetoric, substituting a sovereignty violation frame for multilateral cooperation in general.

2. Structural Context

Security Structure: The Integration of North Korean Labor and Russia's Defense Industry

The most tangible aspect of this report is the deployment of North Korean workers to Russian drone factories. Yonhap News reported that some of them are working on military drone production lines [6]. The Kyiv Independent went a step further, reporting on MSMT findings that Russia is bringing them in on student visas to mobilize them for drone production [7]. This is a method of disguising their status by manipulating visa types. It means this is not a simple dispatch of labor, but a structure in which North Korean labor is integrated into Russia's defense industry supply chain.

This structure is an extension of the North Korea-Russia military-technical cooperation that has accumulated since the 2023 Vostochny summit [5]. North Korea is providing troops, artillery shells, and now even drone production personnel. In return, Russia is leaving a trail of evidence of sensitive technology transfers, such as reactors for nuclear-powered submarines and air defense systems [3][5]. The fact that labor dispatch has moved beyond a means of earning foreign currency to a stage of involvement in weapons production itself directly links this issue to European security. If some of the drones Russia deploys on the Ukrainian front are produced by North Korean labor, this becomes not a Northeast Asian issue but a component of Europe's security supply chain. This provides the grounds for cooperation between NATO and the IP4 (South Korea, Japan, Australia, New Zealand) to expand beyond symbolic expressions of solidarity to the practical agenda of supply chain monitoring.

Economic Structure: China as a Monitoring Blind Spot

The MSMT report states that North Korean workers are active in at least 17 countries, concentrated mainly in China and Russia [4]. However, the specific cases detailed in the report are focused on the Russian drone factories [6][7]. Although China is identified as the largest host of North Korean workers, specific violations at the worksite level are relatively unexposed. This is related to the structural limitation that the MSMT's intelligence-gathering capabilities depend on the accessibility of Western intelligence agencies. While trends within Russia are largely captured by Western intelligence networks through the lens of the Ukraine war, the situation of North Korean workers in China does not have a comparable path to exposure. Consequently, the effectiveness of sanctions implementation depends on the cooperation of China, the largest host country, which is effectively outside the monitoring network. Whether the agenda of a U.S.-China summit includes the issue of repatriating North Korean workers will be the variable that determines if the report's recommendations remain on paper or lead to actual implementation.

Political Structure: The Sanctions Regime as a Contest of Legitimacy

The sources of enforcement power differ between a monitoring system based on Security Council resolutions and one based on a minilateral group. The former, despite the constraint of the permanent member veto, formally has binding force on all 193 UN member states. The latter relies on the implementation measures of the participating countries themselves. The MSMT's call for countries to "repatriate North Korean workers and refuse to issue new work permits" [4] takes the form of urging implementation of a Security Council resolution, but actual enforcement is left to the domestic laws and policy will of individual nations. The participation of major European countries in this group is an attempt to transfer the authority of the original resolutions to a minilateral framework. North Korea's insistence on questioning the legitimacy of the monitoring body is a response intended to block this transfer attempt itself.

3. Historical Precedents and Comparison with Similar Cases

The dynamic of a Panel of Experts being dissolved and a minilateral monitoring system emerging is not an entirely new phenomenon. The Coordinating Committee for Multilateral Export Controls (COCOM), the Cold War-era export control regime against the Soviet bloc, was also a voluntary group of Western countries, not a UN body. It had no enforcement power but secured a degree of effectiveness through information sharing and policy coordination among participating states. The structure of the MSMT is similar. Its effectiveness depends less on legal binding force and more on the political will of its members and the density of their information sharing.

The relationship between the IAEA and North Korea also shows a similar pattern of denying legitimacy. Since expelling inspectors in 2009, North Korea has completely blocked the IAEA's on-site access. Regarding the recent IAEA report that identified a new uranium enrichment facility at Yongbyon, Russia also disparaged it with the logic that "the evidence is insufficient because the IAEA has no access to North Korea" [10][16]. This is a method of undermining the credibility of the report itself based on the monitoring body's lack of access. Although Russia has not yet issued an official position on the MSMT report, the possibility remains that the rhetoric seen in the IAEA case will be repeated. If the combination of a permanent Security Council member directly denying the legitimacy of a Western-led monitoring body is also applied to the MSMT, North Korea's "conspiracy group" label will gain real power beyond mere diplomatic rhetoric.

The issue of worker dispatch itself is not new. Even after the 2019 Security Council resolution, the presence of North Korean workers abroad was never completely terminated. The fact that the figures presented in this report are actually higher than previous estimates [1][9] shows that the gap between the text of the sanctions resolutions and the reality of their implementation has widened since the change in the monitoring system.

4. Key Variables Shaping Future Developments

First is Russia's approach to the MSMT. The key question is whether Russia will apply the "lack of access" logic [10] it used against the IAEA report to the MSMT report as well. If Russia joins this framing, it will create a dynamic where a permanent Security Council member and a sanctioned state simultaneously deny the legitimacy of the monitoring body.

Second is the agenda of the U.S.-China summit. Whether China, the largest host of North Korean workers, will respond to repatriation demands depends on whether the issue is included in the negotiation package of a bilateral summit. If it is not included, the MSMT's recommendations will be only partially implemented, limited to the Russia-related cases.

Third is whether the NATO-IP4 cooperation agenda deepens. Depending on how specifically European countries problematize the fact that the deployment of North Korean personnel on drone production lines [6][7] is directly linked to arms supplies for the Ukrainian front, this issue will either remain at the level of symbolic condemnation or lead to tangible supply chain interdiction measures.

Fourth is South Korea's policy mix. The South Korean government's policy of engagement with North Korea and its commitment to sanctions implementation as an MSMT member could send signals in different directions. Whether it is possible to pursue both policies in parallel, or if a choice to prioritize one is inevitable, will become a central axis of future policy debates.
