Abstract
The 2021 military coup in Myanmar and the subsequent collapse of democratic governance have triggered a complex and protracted crisis with profound implications for Southeast Asia and its broader neighborhood. This paper critically examines the multidimensional threats posed by post-coup instability in Myanmar to regional order and cross-border security dynamics. It explores the implications for human security, insurgency proliferation, refugee flows, transnational crime, and regional institutional efficacy, particularly within ASEAN. Drawing on theories of regional security complexes and empirical developments since the coup, the analysis highlights Myanmar’s transformation into a critical node of instability in the Indo-Pacific, with spillover effects extending into neighboring states such as India, Thailand, China, and Bangladesh.
1. Introduction: Myanmar’s Coup and Regional Reverberations
On February 1, 2021, the Tatmadaw (Myanmar’s military) staged a coup, deposing the elected government of Aung San Suu Kyi and declaring a state of emergency. This event reversed a decade of quasi-democratic reform and has since led to massive civil unrest, armed resistance, and widespread violence, plunging the country into a state of near civil war.
This instability is not confined within Myanmar’s borders. It poses significant risks to regional order and cross-border security, particularly in Southeast and South Asia. The coup has destabilized existing diplomatic arrangements, created humanitarian crises, and undermined regional mechanisms for conflict management, making Myanmar a focal point for regional insecurity.
2. Spillover Effects on Neighboring States
a. Refugee Flows and Humanitarian Fallout
One of the most immediate consequences of the post-coup crisis has been the massive displacement of civilians. As violence escalates between the military and opposition forces—including ethnic armed organizations (EAOs) and the People’s Defence Forces (PDFs)—thousands have fled to neighboring countries.
- India (particularly Mizoram and Manipur) has received thousands of ethnic Chin refugees, placing strain on local resources and inflaming ethnic tensions.
- Thailand has faced refugee inflows across its western border, with intermittent military activity spilling into Thai territory.
- Bangladesh, already hosting nearly one million Rohingya refugees, fears renewed persecution and outflows from Rakhine State.
The unregulated movement of displaced populations presents serious health, security, and governance challenges, including the risk of radicalization, human trafficking, and disease outbreaks, exacerbated by the absence of a coordinated regional response.
b. Insurgency Proliferation and Border Militarization
Myanmar’s internal conflict has become increasingly militarized, with numerous ethnic armed groups reasserting control over their territories and aligning with anti-junta resistance forces. The consequence is a fragmentation of state authority, particularly in border regions.
- The India-Myanmar border has witnessed renewed activity by militant groups, including Naga, Manipuri, and Mizo insurgents, who use the porous border to evade security forces and conduct operations.
- China faces instability along its southwestern border, where ethnic Chinese armed groups and criminal syndicates have historically operated with relative autonomy.
- Thailand’s border regions have also seen a resurgence of cross-border gunfire, and the Thai army has bolstered its presence to prevent the conflict from spilling further into its territory.
The crisis thus risks transforming Myanmar into a regional insurgent sanctuary, weakening state capacities in adjacent regions and complicating bilateral relations.
3. Transnational Crime and Illicit Economies
In the power vacuum created by political collapse and weakened law enforcement, illicit activities have flourished:
- Drug trafficking from the Golden Triangle has surged, with Myanmar remaining a major producer of methamphetamines and heroin.
- Illegal arms flows have increased, arming both state and non-state actors, and heightening the risk of regional arms proliferation.
- Human trafficking and wildlife crimes have intensified, particularly in areas under the control of semi-autonomous militias and warlords.
These dynamics threaten to undermine rule of law and state legitimacy in neighboring countries. The growth of transnational criminal networks also impairs efforts to create a rules-based regional order, a key pillar of ASEAN’s security architecture.
4. ASEAN’s Credibility and Regional Norms
The Myanmar crisis presents a severe normative and institutional challenge for the Association of Southeast Asian Nations (ASEAN).
- ASEAN’s non-interference principle has historically limited its ability to manage internal conflicts of member states. However, the scale of Myanmar’s crisis has pressured ASEAN to act more decisively.
- The Five-Point Consensus, adopted in 2021 to guide conflict resolution, has been largely ignored by the junta, undermining ASEAN’s legitimacy.
- Myanmar’s rotating chairmanship and participation in ASEAN meetings have become points of contention, revealing divisions among member states.
ASEAN’s inability to enforce compliance or facilitate meaningful dialogue has led to questions about its relevance as a regional security provider, opening space for extra-regional actors to influence outcomes, including China, India, and the United States.
5. Strategic Competition and Great Power Involvement
Myanmar’s geostrategic location at the crossroads of South and Southeast Asia, along with its proximity to the Indian Ocean, makes it a focal point of great power rivalry:
- China has maintained diplomatic engagement with the junta, driven by strategic investments in infrastructure under the Belt and Road Initiative (BRI), particularly the China-Myanmar Economic Corridor (CMEC). Its role has been marked by ambivalence, balancing between political risk management and the protection of strategic assets.
- India, while concerned about instability along its eastern flank, has maintained a cautiously pragmatic stance, balancing security interests with its “Act East” policy.
- Western countries, especially the United States and the EU, have imposed sanctions and emphasized democratic restoration, but have limited leverage due to minimal economic and security engagement compared to regional powers.
The crisis has thus become a site of contestation where normative agendas (democracy vs. authoritarianism) intersect with strategic interests, increasing the risk of a proxy dynamic that could further destabilize the region.
6. Regional Security Complex Theory: A Framework for Understanding Myanmar’s Impact
Applying Barry Buzan and Ole Wæver’s Regional Security Complex Theory (RSCT), Myanmar can be seen as a core destabilizing unit within the South and Southeast Asian security complexes. Its internal security issues interact with neighboring states, generating regionalized insecurity that cannot be contained within its borders.
RSCT’s emphasis on security interdependence illustrates why Myanmar’s crisis requires multilateral responses. The cross-border impact on human security, insurgency, and transnational crime supports the need for enhanced sub-regional cooperation, possibly through a reinvigorated role for BIMSTEC or India-ASEAN frameworks.
Conclusion: A Node of Instability in the Indo-Pacific Order
The post-coup instability in Myanmar constitutes a serious threat to regional order and cross-border security dynamics, with implications that extend beyond national boundaries. The fragmentation of state authority, growing insurgent activities, transnational criminal networks, and unregulated refugee flows challenge the capacities of neighboring states and regional institutions alike.
Moreover, the geostrategic contest involving major powers adds a layer of complexity to any resolution. While the normative framework of ASEAN has struggled to respond effectively, other multilateral platforms and bilateral diplomacy may play a greater role in shaping outcomes.
In sum, Myanmar’s crisis represents not just a national tragedy, but a regional security dilemma, demanding sustained attention, coordinated strategies, and a recalibration of regional norms to preserve peace and stability in the Indo-Pacific.
