This study examines how North Korea exploits vulnerabilities in maritime transportation and legal gray zones under the United Nations Security Council sanctions regime to evade sanctions, and analyzes the role and effectiveness of the Proliferation Security Initiative (PSI) in responding to these practices, thereby exploring both the limitations and the potential of international maritime security governance. Focusing on the changes in sanctions and countermeasures since the launch of the PSI from 2003 to 2025, the study analyzes the strategic patterns through which North Korea has adapted to international surveillance mechanisms and maximized the efficiency of its sanctions evasion practices.
The study reviews PSI policy documents, United Nations Security Council resolutions, and North Korean legislation related to illicit maritime shipping, and conducts qualitative analysis of specific cases such as ship to ship transfers and flag laundering to assess the operational achievements and structural limitations of the PSI. By integratively applying three theoretical frameworks, namely the regulatory paradox, smuggling state theory, and gray zone strategy, the study analyzes the interactive structure of sanctions, evasion, and countermeasures.
The main findings of this study are as follows. First, following the So San incident in 2002 and the subsequent recognition of the need for the establishment of the PSI, North Korea began to intensify its maritime sanctions evasion efforts. After the launch of the PSI, North Korea systematized multilayered transshipment strategies and vessel identity laundering techniques through cooperation with China and Russia, and the non cooperative posture of major powers played a decisive role in shaping the origins of these evasion strategies. Second, the PSI failed to achieve systematic interdiction due to the absence of legal binding force and the lack of cooperation from key states. Despite the success of individual interdiction operations such as the BBC China case, it was unable to dismantle structural sanctions evasion networks, while organized evasion techniques became increasingly sophisticated in proportion to the tightening of sanctions. This clearly demonstrates the regulatory paradox. Third, following the systematic non cooperation of China and Russia, North Korea evolved toward smart evasion methods after the Wise Honest incident in 2018, including dual registration, crypto currency based money laundering, and cyber technologies. Fourth, recognizing the limitations of individual interdictions, the international community strengthened multilateral maritime surveillance mechanisms following the establishment of the PSI and the Pacific Security Maritime Exchange (PSMX). As of 2025, minilateral cooperation centered on South Korea, the United States, and Japan has emerged as a new model of international maritime security governance.
The dissertation applies three theoretical frameworks. First, the regulatory paradox explains the vicious cycle in which stronger sanctions lead to increasingly sophisticated evasion techniques. Second, smuggling state theory illustrates North Korea’s state organized mobilization of national capacity for sanctions evasion. Third, gray zone strategy explains how the interaction between sanctions and countermeasures unfolds within the domain of coercion below the threshold of war.
In conclusion, North Korea’s maritime sanctions evasion originated under the influence of the PSI beginning in 2003, took shape between 2006 and 2017 in response to the strengthening of international sanctions, and has been further reinforced since 2018 amid major power non-cooperation and gaps in international law. Despite the success of individual interdiction operations, the failure to dismantle structural sanctions evasion networks reveals the fundamental limitations of the PSI. Nevertheless, the international community is exploring a new model of international maritime security governance by strengthening minilateral cooperation centered on South Korea, the United States, and Japan. To overcome the vicious cycle of sanctions, evasion, and countermeasures, a paradigmatic shift toward a balance between pressure and cooperation is essential.
