The Reality on the Naf Frontier: Why Dhaka Must Rethink Its Approach to Border Security

By Oo Kyaw Thar ၊ Opinion ၊ June 23, 2026

The Arakan–Bangladesh frontier has emerged as one of South Asia’s most sensitive and least understood borderlands. In Dhaka, public debate is often shaped by concerns over refugee pressures, cross-border insecurity, and the spillover effects of Myanmar’s prolonged conflict. Yet this framing increasingly overlooks a fundamental development: the political and security order along the Naf River has undergone a significant transformation.

In recent years, segments of Bangladeshi media and commentary have portrayed the Arakan Army (AA) primarily as a destabilizing actor, particularly in relation to reports involving the detention of Bangladeshi fishermen near the maritime boundary. Such incidents are frequently described as arbitrary arrests or abductions. While Bangladesh’s security concerns are legitimate and merit attention, these interpretations do not always fully reflect the evolving realities on the ground in Arakan State.

A more accurate assessment requires attention not only to individual incidents, but also to the changing structure of authority that now shapes border governance.

The Persistent Issue of Illegal Cross-Border Fishing

Illegal fishing across the Arakan–Bangladesh maritime frontier has long been a recurring feature of the region. For decades, Bangladeshi fishing vessels have intermittently entered waters administered by Myanmar to engage in illegal fishing, a practice that persisted in part due to limited enforcement capacity and insufficient attention to safeguarding maritime boundaries by Myanmar governments. Successive civilian and military authorities in Naypyidaw faced significant limitations in monitoring and regulating maritime boundaries in this area, allowing such practices to become relatively routine over time.

This pattern is now changing.

With the Arakan Army exercising effective control over much of the border region, maritime governance has become more structured and actively enforced. Patrols have increased, fishing activity is more closely monitored, and territorial waters are regulated with greater consistency than in previous years.

In this context, the detention of fishermen should be understood within a specific territorial and administrative framework. In all reported cases, such incidents occur after vessels enter waters under Arakan administration illegally. There is no indication that the Arakan Army has conducted cross-border enforcement actions into Bangladeshi territory.

This distinction is not merely technical; it is foundational. Under widely recognized international practice, authorities exercising de facto control over a territory or maritime zone retain the right to regulate activities within that area and enforce applicable rules. Whether or not the Arakan Army is formally recognized does not alter the operational reality of control on the ground.

A more constructive approach would shift attention away from isolated confrontations and toward prevention, particularly through improved maritime awareness, clearer communication of boundary practices, and practical mechanisms to reduce repeated incidents of illegal fishing.

A Broader and More Complex Security Environment

The illegal fishing issue represents only one dimension of a broader and more complex security environment along the frontier.

Since the escalation of conflict in Myanmar, the Arakan–Bangladesh border region has become increasingly affected by transnational criminal activity and irregular armed movements. Reports of human trafficking, narcotics smuggling, kidnapping, and cross-border criminal networks reflect a setting in which traditional enforcement mechanisms face sustained pressure.

Security concerns have also been raised in relation to refugee settlements in Bangladesh, where authorities have at times reported the presence or influence of armed actors.

From the perspective of authorities exercising control in Arakan, this environment introduces additional security considerations, including concerns about infiltration and the potential use of civilian activities, such as illegal fishing, as cover for movement across sensitive areas. Whether every reported incident can be independently verified is less central than recognizing that such perceptions materially shape enforcement behavior in conflict-affected borderlands.

In such conditions, border governance often becomes precautionary by necessity, as authorities attempt to balance civilian livelihoods with evolving security risks.

The Emergence of a New Political Reality

The most consequential factor reshaping the Arakan–Bangladesh frontier is the emergence of a new political reality.

Over the past two years, the Arakan Army has made significant territorial gains against Myanmar’s military and now exercises effective control over most of Arakan, including the entire border with Bangladesh. This development has significantly altered the operational environment of border management.

In international practice, engagement is not determined solely by formal recognition but also by effective authority. Across multiple conflict settings, states have engaged with de facto authorities when required by security, humanitarian, or administrative necessity. The Arakan–Bangladesh frontier increasingly reflects this pattern.

The Arakan Army and its political wing, the United League of Arakan (ULA), now perform core governance functions across large areas of territory. These include maintaining local order, administering services, managing movement, and overseeing security structures.

Regardless of political considerations, these functions directly shape conditions along the border and therefore cannot be excluded from practical policy analysis.

For Bangladesh, continued reliance on traditional state-to-state assumptions risks creating a growing gap between diplomatic frameworks and operational realities on the ground.

The Refugee Repatriation Challenge

This gap is particularly evident in discussions surrounding (Rohingya) refugee repatriation.

Bangladesh continues to host more than one million displaced refugees, bearing a substantial humanitarian, economic, and security burden. Despite sustained diplomatic efforts, repatriation initiatives have not progressed due to ongoing insecurity in Arakan, limited trust, and the absence of credible guarantees for safe return.

At the center of the issue lies a basic but unavoidable question: who holds effective authority over areas of intended return?

In much of northern Arakan, governance is increasingly exercised by actors with de facto control. Any viable repatriation framework will therefore require engagement with all parties capable of ensuring security, access, and administrative functionality on the ground.

Excluding relevant stakeholders may align with political sensitivities, but it is unlikely to produce sustainable outcomes.

A durable solution requires a pragmatic focus not on recognition, but on implementation.

From Confrontation to Managed Cooperation

The Arakan–Bangladesh frontier should not be defined by mutual suspicion or reactive political narratives. Communities along the Naf River share longstanding economic, cultural, and social ties that predate modern borders. Their stability depends on predictable border governance, secure livelihoods, functioning trade channels, and effective management of cross-border risks.

These are shared interests rather than competing ones.

Rather than treating each incident as a diplomatic flashpoint, policymakers and analysts may find greater value in developing structured mechanisms for cooperation. These could include improved communication channels between border authorities, coordinated approaches to transnational crime, maritime awareness initiatives, and confidence-building measures aimed at reducing avoidable friction.

Such an approach does not require Bangladesh to alter its formal diplomatic positions. It requires only a closer alignment between policy assumptions and the realities of enforcement on the ground.

In international affairs, effective policy begins with accurate diagnosis. Along the Naf frontier, that diagnosis has changed significantly. The central question for Dhaka is not whether this transformation is desirable, but how policy should adapt to manage its consequences.

As the balance of power along the Arakan–Bangladesh border continues to evolve, pragmatic engagement not political denial offers the most viable path toward sustainable border security, regional stability, and long-term solutions to one of South Asia’s most persistent frontier challenges.
