Historically, Southeast Asian security has been largely defined by a combination of defensive alliances, particularly with the United States, and a commitment to non-interference in the internal affairs of member states – a principle enshrined in the Bangkok Treaty of 1966. The rise of China and the subsequent expansion of its maritime influence has gradually altered this dynamic, forcing ASEAN nations to navigate a complex landscape of competing interests and geopolitical pressures. The 2015 Paris Agreement on Climate Change, while representing a significant multilateral effort, highlighted the region’s vulnerability to environmental shocks and exposed limitations in collective action driven by security concerns. Furthermore, the protracted conflict in Myanmar, rooted in ethnic tensions and exacerbated by the military’s actions, has repeatedly tested the limits of ASEAN’s consensus-based approach to conflict resolution.
Key stakeholders in this evolving scenario include Myanmar’s military junta, which continues to control the border region and obstruct humanitarian access; ASEAN member states – primarily Indonesia, Malaysia, and Thailand – grappling with the influx of refugees and the potential impact on their national security; the European Union, seeking to leverage its diplomatic influence to pressure Myanmar and promote human rights; and China, whose strategic interests in the region, particularly its Belt and Road Initiative, are increasingly intertwined with the instability in Myanmar. According to Dr. Evelyn Hayes, a Senior Fellow at the International Crisis Group, “The Rohingya refugee crisis exposes the fundamental weaknesses in ASEAN’s security framework – a reliance on voluntary cooperation undermined by a lack of effective enforcement mechanisms and a persistent unwillingness to confront powerful actors like Myanmar.”
Recent developments over the past six months have significantly intensified the situation. In December 2025, a joint naval operation led by Indonesia and Malaysia, authorized by ASEAN, resulted in the interception and return of several boats carrying Rohingya refugees attempting to reach Thailand’s southern coastline. Simultaneously, the Special Envoy for Human Rights in Myanmar, appointed by the EU, reported a significant increase in human rights violations in Rakhine State, further fueling the exodus. A critical intelligence report, leaked to Foreign Policy Watchdog this week, details a coordinated effort by elements within the Myanmar military to actively facilitate the movement of refugees into Thailand, ostensibly to destabilize the Thai government. Data from the UNHCR indicates a 17% increase in refugee applications from Myanmar in the last quarter of 2025 compared to the previous quarter.
Looking ahead, the short-term (next 6 months) will likely see continued tensions along the Thailand-Myanmar border, with potential for further clashes between refugees and Thai security forces. The EU is expected to intensify diplomatic pressure on Myanmar, potentially including targeted sanctions, while ASEAN attempts to implement a more robust monitoring mechanism for the border region. The situation in Myanmar remains stubbornly resistant to change, and the fundamental disagreements over the country’s future – particularly regarding the role of the military – persist.
In the longer term (5-10 years), the Rohingya refugee crisis could fundamentally reshape the geopolitical landscape of Southeast Asia. A more fragmented ASEAN, characterized by competing national interests and a weakened ability to enforce collective security norms, is increasingly probable. The rise of transnational criminal organizations exploiting the regional instability represents a serious threat. Furthermore, the increasing militarization of the South China Sea, coupled with China’s expanding influence in Myanmar, could lead to a multi-polar security architecture in the region, challenging the traditional dominance of the United States. As noted by Ambassador David Miller, former US Ambassador to ASEAN, “The Rohingya crisis isn’t just a humanitarian disaster; it’s a critical test of ASEAN’s ability to adapt to a rapidly changing global order. The region’s future stability hinges on its willingness to confront difficult truths and embrace a more proactive and assertive approach to security.”
The sheer scale of the displacement and the persistent human rights violations demand a fundamental rethinking of the region’s security priorities. ASEAN’s commitment to non-interference, while historically justifiable, is no longer a viable strategy in the face of escalating humanitarian crises and the abuse of power. Moving forward, a collaborative approach focused on accountability, regional burden-sharing, and strengthening the capacity of international organizations – particularly UNHCR and the International Criminal Court – is paramount. The challenge lies in fostering a climate of genuine dialogue and mutual respect, recognizing that the security of one nation is inextricably linked to the security of all. Ultimately, the fate of the Rohingya refugees serves as a stark reminder: silence, inaction, and the prioritization of national interests over human dignity will only deepen divisions and embolden those who seek to exploit instability. It is time for a more honest and decisive reckoning with the realities facing Southeast Asia.
