Behind the thick jungles and winding rivers that separate Myanmar from its neighbours, a dangerous new fault line is emerging. The Arakan Army (AA), an ethnic Rakhine insurgent group, has dramatically advanced into key areas of Myanmar’s Rakhine State, capturing critical military installations and border posts along the frontier with Bangladesh. This sudden surge of insurgent power is upending the region’s fragile balance, raising urgent questions about refugee flows, cross-border militancy, and the strategic ambitions of giants like India and China.

Arakan Army’s New Footprint:


In a matter of weeks, the Arakan Army—long a thorn in the side of Myanmar’s beleaguered military regime—has seized Maungdaw in Rakhine State. Even more troubling for regional stability is the AA’s capture of strategic border posts, notably the BGP-5 base along the Myanmar-Bangladesh frontier. Satellite images and ground reports suggest the AA now controls a vital chokepoint dictating who enters and exits Myanmar along one of the most porous and sensitive borders in Asia.

The group’s presence in these vital areas raises fresh security dilemmas. With the AA positioned squarely at the gates, the question that analysts in Yangon and Dhaka are asking is: Will the Arakan Army push further, crossing into Bangladeshi territory next? Speculation centers on the potential targeting of Chittagong, a bustling port city with a diverse population mix—including roughly 25% Hindus and 5% Christians. Any infiltration or assault here would risk inflaming long-standing religious and ethnic tensions, possibly reverberating across the broader South Asian landscape.

Bangladesh on the Brink:
Bangladesh, already hosting over 740,000 Rohingya refugees since the brutal 2017 crackdown in Myanmar, finds itself edging toward a humanitarian tipping point. The renewed instability, spurred by the AA’s advances, threatens to send yet another wave of desperate families fleeing violence. Border officials and NGOs brace for a fresh influx that could strain Dhaka’s resources—already stretched thin by the refugee crisis—and compound ethnic and religious resentments simmering beneath the surface.

“What we are witnessing is a destabilization with ramifications that go far beyond Myanmar’s frontiers,” says a Dhaka-based security analyst. “If more Rohingya spill over, Bangladesh’s fragile sociopolitical fabric risks tearing further.”

For Bangladesh’s Prime Minister Sheikh Hasina, any deterioration on the frontier poses daunting challenges—both political and economic. Slowing the influx of refugees and maintaining communal harmony within Bangladesh’s borders could prove an uphill task if the AA’s insurgency destabilizes Rakhine further. Amid this, Dhaka’s quest for regional support—especially from India—will likely intensify.

India’s Delicate Balancing Act:
New Delhi’s vantage point on this turmoil is far from detached. India shares a 1,600-km porous border with Myanmar, a frontier historically prone to the cross-border flow of contraband, arms, and undocumented migrants. In Manipur and Mizoram, Indian security officials are already on alert. The AA’s growing influence could push more displaced persons, perhaps even battle-hardened fighters and traffickers, into India’s Northeast—an area already grappling with complex ethnic tensions and insurgencies of its own.

Even more critical is the potential impact on India’s $500 million Kaladan Multimodal Transit Transport Project, a flagship connectivity initiative linking India’s Eastern coastline with the Northeast via Myanmar’s troubled Rakhine State. If the AA solidifies its hold near these transit points, it could derail India’s carefully laid economic and strategic plans, giving New Delhi fresh headaches in a region where it vies with China for influence.

“Instability in Myanmar directly undercuts India’s aspirations to secure its eastern flank and improve connectivity,” notes a senior Indian diplomat familiar with the matter. “We need to tighten border security and engage in discreet but robust diplomacy to ensure that the region does not slide into chaos.”

China’s High-Stakes Gamble:
For Beijing, the Arakan Army’s gains come at a particularly delicate moment. China has long backed Myanmar’s ruling military junta, seeing the relationship as a gateway to the Indian Ocean and a means to expand its Belt and Road footprint. With the junta struggling to contain the AA’s advance, China’s grip on Myanmar’s internal politics could loosen.

Beijing’s financial leverage—reports suggest around 40% of Myanmar’s external debt is owed to China—might soften the blow, but the unrest complicates matters. China has invested heavily in infrastructure projects in Myanmar’s conflict-ridden western flank. The AA’s advance threatens to disrupt these projects and dent Beijing’s efforts to normalize the junta on the international stage.

“China’s strategy relies on a stable Myanmar regime that can ensure smooth operations of its investments,” explains a security scholar from a Singapore-based think tank. “If the AA keeps scoring victories, Beijing’s carefully curated image as a stable, development-oriented backer will be tarnished, and it may struggle to protect its assets on the ground.”

A Global Flashpoint with Limited Diplomacy:
As the Arakan Army’s stealth and firepower reshape the ground realities, global powers have shown limited levers of influence. Western states, including the US and the EU, remain focused on sanctions that isolate the junta without directly engaging the AA or addressing the deeper ethnic and political fissures at play. Without robust diplomatic intervention, the region risks devolving into a hotspot of conflicting interests, shadowy alliances, and perpetual instability.

India, for its part, must step carefully. Gaining an upper hand in this complex scenario requires deft navigation—balancing humanitarian responsibilities, border security interests, and the strategic imperative to counter China’s dominance in Southeast Asia. New Delhi’s moves will influence how this tinderbox evolves. Enhancing security measures, deepening intelligence cooperation with Dhaka, and possibly opening backchannels with select stakeholders in Myanmar might be on the cards.

The Road Ahead:
As of now, the Arakan Army shows no sign of retreat. The key questions—whether it will cross into Bangladesh, how Dhaka will respond to a new flood of refugees, how India’s Northeast will cope with renewed instability, and whether China can still script a favorable outcome—remain unanswered.

For the millions caught in the middle, uncertainty looms large. The region stands at a crossroads: either stakeholders come together in a delicate diplomatic dance to restore stability, or the fragile fault lines deepen into a full-blown regional crisis. The next moves by the Arakan Army and the responses from Dhaka, New Delhi, and Beijing will determine whether the borderlands of Myanmar turn into an active crucible of conflict or find a narrow path back from the brink.
