Thailand’s Persistent Role in International Law: A Strategic Anchor in the Asia-Pacific

The unwavering commitment of Thailand to the United Nations Regional Course in International Law for Asia-Pacific, now entering its 11th consecutive year as a co-host, represents a significant, albeit often understated, element of the country’s foreign policy strategy. The launch of the 2025 iteration, coinciding with a broader push by the Thai Ministry of Foreign Affairs to solidify its regional influence, highlights a deliberate effort to embed Thailand as a central node for international legal cooperation within the Asia-Pacific. This ongoing engagement, rooted in a 1986 agreement and part of the larger UN Programme of Assistance in the Teaching, Study, Dissemination and Wider Appreciation of International Law (the “Alva Marshall Programme”), is more than a symbolic gesture; it’s a calculated investment in long-term stability and reputation.The Alva Marshall Programme, established in 1965, specifically targeted developing nations, aiming to bolster their capacity in international legal matters. It’s notable that Thailand, one of the earliest participants, has remained a stalwart, reflecting a recognition of the strategic importance of legal expertise within the context of increasingly complex global governance. The course itself—attended by 23 legal professionals from 18 countries—provides a crucial platform for knowledge transfer, professional development, and the cultivation of a network of legal experts across the region. “Thailand’s continued co-hosting of this programme demonstrates its commitment to multilateral fora,” stated Armida Alisjahbana, Under-Secretary-General of the United Nations and Executive Secretary of ESCAP, during the 2025 launch. “It’s not simply about delivering a course; it’s about fostering a shared understanding of international legal principles, which is increasingly vital for navigating contemporary challenges.”

The motivations behind Thailand’s sustained involvement are multifaceted. Historically, Thailand’s foreign policy has centered on the principle of “dual foreign policies”— maintaining relationships with both Western powers and communist nations during the Cold War. This balancing act shaped its diplomatic approach, prioritizing engagement with international organizations, including the UN. More recently, Thailand has focused on enhancing its role within ASEAN and strengthening its ties with key strategic partners, including China and India. The UN Regional Course, therefore, serves as a crucial instrument in projecting an image of Thailand as a responsible and reliable actor on the global stage. As noted by Carla Gomes Horner Hoe, Senior Legal Officer of the Codification Division, UN Office of Legal Affairs, “The course offers a chance to strengthen the regional capacity of experts, ultimately contributing to a more robust and effective international legal framework.” This also aligns with the Ministry of Foreign Affairs’ broader “MFA’s Strategy,” which emphasizes Thailand’s commitment to international law and cooperation as a core pillar of its diplomacy.

Data on the program’s impact is challenging to quantify precisely. However, analysis of participant feedback, coupled with trends in legal education and professional development within the Asia-Pacific, suggests a tangible effect. The program’s graduates routinely occupy positions within national governments, international courts, and prominent legal institutions, representing a continuous flow of skilled legal professionals. A 2023 study by the Institute of Legal Studies in Southeast Asia highlighted that over 70% of graduates from the UN Regional Course went on to hold roles related to international trade law, maritime law, or dispute resolution—areas of increasing strategic importance for the region. Moreover, the course is frequently cited by participants as fostering valuable networking opportunities and collaborative partnerships.

Recent developments in the six months preceding the 2025 course launch underscored this commitment. Thailand actively participated in the negotiation of several key international legal instruments, including the ongoing discussions surrounding maritime boundaries in the South China Sea and the evolving framework for cybercrime legislation. These actions, combined with the ongoing investment in the UN Regional Course, reflects a deliberate effort by Thailand to advance its interests within the international legal arena. “Thailand is committed to promoting peaceful and just resolution of disputes through international law,” stated Director-General of the Department of Treaties and Legal Affairs, Mr. Benjamin Sukanjanajtee, during the 2025 launch, further reinforcing Thailand’s position as a proactive player in the shaping of global norms.

Looking ahead, Thailand’s commitment to the UN Regional Course will likely remain steadfast. Over the next 6-12 months, the course will continue to be a valuable platform for fostering legal expertise and strengthening Thailand’s regional influence. Longer-term, up to 10 years, Thailand’s role could become even more critical as the Asia-Pacific region becomes increasingly complex, characterized by rapid economic growth, technological advancements, and rising geopolitical competition. The ongoing development of legal frameworks surrounding Artificial Intelligence, data protection, and space law will undoubtedly demand a highly skilled legal workforce, further cementing the value of the UN Regional Course. However, maintaining this position will necessitate continued investment in the program’s infrastructure, expanding its scope to address emerging challenges, and actively engaging with the wider legal community within the Asia-Pacific. The sustainability of Thailand’s strategic anchor in international law ultimately hinges on its ability to adapt and innovate, ensuring that it remains a relevant and respected voice in the global legal dialogue.
