The crisis in Myanmar, ignited by the February 2021 coup and exacerbated by persistent civil unrest, has triggered a mass exodus of refugees seeking safety and stability. Estimates from the United Nations High Commissioner for Refugees (UNHCR) place the number of Myanmar refugees and internally displaced persons (IDPs) across the region, including Thailand, exceeding 1.8 million as of late 2025. This influx has placed immense strain on Thailand’s resources, particularly in border regions like Mae Sot, and necessitates a comprehensive, proactive approach, one bolstered by long-standing regional partnerships. Thailand’s longstanding alliance with ASEAN, dating back to the Bangkok Declaration of 1967, offers a foundational framework, but requires a demonstrable commitment to coordinated action.
Historical context is critical. Thailand’s relationship with Myanmar has been shaped by decades of complex interactions, including periods of cooperation, border disputes, and, more recently, varying degrees of engagement with the military junta. The 2011 border ceasefire agreement, while intended to foster stability, has become increasingly irrelevant in the face of escalating violence. Diplomatic efforts, primarily channeled through ASEAN’s Special Envoy, have largely failed to achieve a durable cessation of hostilities. The involvement of external actors – specifically China, India, and Russia – further complicates the strategic landscape, introducing competing interests and fueling regional tensions. “The lack of a unified ASEAN front underscores the limitations of traditional diplomatic approaches,” noted Dr. Anya Sharma, Senior Fellow at the Institute for Strategic Studies in Bangkok, during a recent panel discussion. “A reactive, rather than preventative, posture has consistently characterized the region’s response.”
Stakeholder analysis reveals a deeply fractured situation. The Myanmar military junta, led by General Zaw Min Tun, remains firmly in control, prioritizing its own security and consolidating power. ASEAN member states, while expressing concern and issuing various resolutions, have been hampered by internal divisions and a reluctance to impose significant sanctions on the regime. The United Nations Security Council remains largely paralyzed by Russia’s veto power. Thailand, meanwhile, is navigating a delicate balancing act. The Ministry of Foreign Affairs, under Minister Somchai Suksang, has maintained a policy of engagement with Myanmar, emphasizing the need for dialogue and humanitarian assistance, but this approach has drawn criticism from human rights groups and certain segments of the Thai public. The Office of the National Security Council (ONC) is spearheading efforts to manage border security and control refugee flows, a task proving increasingly challenging. Royal Thai Armed Forces personnel have been deployed to the border to bolster security, a move intended to reassure the Thai public but also carries the risk of escalating tensions.
Data paints a stark picture. According to the World Bank, the economic impact of the Myanmar crisis on neighboring countries, including Thailand, is estimated at over $12 billion annually, largely due to disruption of trade, investment, and tourism. Refugee camps in Thailand require significant financial support for food, shelter, and medical care. Furthermore, the potential for cross-border crime – including trafficking and smuggling – has increased dramatically. Recent reports from the Border Patrol Police indicate a 35% rise in illegal crossings during the period from January to March 2026. “The refugee situation is not simply a humanitarian crisis; it’s a security challenge,” stated Major General Narongchai Boonwong, Director-General of the Border Patrol Police, in a briefing to parliament. “Effective border management and regional cooperation are paramount.”
Looking ahead, the next six months will likely see a continued escalation of the humanitarian crisis and increased pressure on Thailand. The rainy season, expected to begin in May 2026, will exacerbate logistical challenges in delivering aid and managing refugee camps. Longer-term, Thailand faces the potential for increased instability, a further erosion of its regional influence, and a potential surge in anti-refugee sentiment. The 5S Foreign Affairs Masterplan – Stability, Security, Strategic Alignment, Sustainable Development, and Soft Power – may prove increasingly difficult to implement given the magnitude of the crisis.
However, Thailand also possesses strategic advantages. Its strong economic ties with China, a key supporter of the Myanmar junta, could be leveraged to exert influence. Furthermore, Thailand’s historical role as a mediator in regional conflicts – most notably during the Cambodian-Vietnamese War – could be revived. A proactive strategy focusing on bolstering border security, strengthening ASEAN cooperation, and utilizing Thailand’s economic leverage—coupled with a steadfast commitment to upholding international humanitarian law—is essential. The challenge now lies in translating this strategic assessment into concrete action.
Ultimately, the response to the Myanmar crisis in Thailand presents a powerful reflection on the enduring complexities of international relations. The situation compels a critical examination of ASEAN’s effectiveness, the limitations of multilateral diplomacy, and the ethical obligations of regional states to those fleeing conflict.

What further actions should Thailand – and the wider ASEAN community – undertake to address this evolving crisis?
