In the diplomacy of the Bay of Bengal, polite public declarations often disguise intense friction. When Brigadier General (Retd) Dr. AKM Shamsul Islam, Defence Adviser to the Bangladesh Prime Minister, arrived in New Delhi for the fifth BIMSTEC National Security Advisers meeting, his public praise of India's leadership in regional security was carefully designed to ease tensions. Yet, behind this diplomatic courtesy lies a complex and fragile relationship. Dhaka’s participation in the July 2026 summit occurred despite a major diplomatic dispute involving the denial of entry to another high-level Bangladeshi official at Delhi airport. This incident threatened to disrupt bilateral relations, making Bangladesh's presence a calculated attempt to balance national dignity with regional security needs.
The meeting occurred as Bangladesh adjusts to a new political landscape under Prime Minister Tarique Rahman, whose administration prioritizes domestic stability and rebuilding institutions. For Dhaka, engaging with India is a strategic necessity rather than a preference, as both nations face shared challenges in maritime security, cyber threats, and the Rohingya refugee crisis.
High Stakes on the Maritime Frontier
The Bay of Bengal is a crucial economic and strategic corridor. It supports a population of 1.7 billion and represents a combined GDP exceeding $5 trillion. This vast maritime area is vital for trade and energy, but its size also makes it highly vulnerable.

As the lead country for security cooperation within BIMSTEC, India is attempting to establish itself as the primary security provider in the region. However, this ambition is complicated by the diverse interests of the other member states: Bangladesh, Bhutan, Myanmar, Nepal, Sri Lanka, and Thailand. While Bangladesh acknowledges India's leadership, it seeks a cooperative approach based on shared responsibility rather than a single dominant power.
Dhaka is particularly concerned about maritime security. This issue is not limited to traditional naval defense. It also involves addressing illegal fishing, smuggling, and protecting critical underwater infrastructure. Submarine communication cables and offshore energy platforms are vital to the region's economy, but they remain vulnerable to accidents and deliberate disruption. For Bangladesh, securing these assets requires practical cooperation, including joint patrols and direct communication channels among regional navies and coast guards.
Diplomatic Friction and Strategic Realities
The New Delhi summit took place against a backdrop of diplomatic tension. The relationship between Bangladesh and India was strained following an incident at Delhi airport, where Prime Minister's Adviser Dr. Zahed Ur Rahman was turned back. Dhaka rejected India’s official explanation of the incident as unsatisfactory, leading to questions about whether Bangladesh would attend the security summit.
"Bangladesh will attend the BIMSTEC National Security Advisers' Meeting... notwithstanding the recent diplomatic row over the treatment of Prime Minister's Adviser Dr. Zahed Ur Rahman at Delhi airport."
Ultimately, Bangladesh chose to attend. This decision reflects a pragmatic approach to foreign policy. As the current chair of BIMSTEC, Dhaka recognized that boycotting the event would weaken its regional position and undermine the multilateral platform. The decision also shows that while bilateral disputes are significant, they are often managed separately from broader regional security agreements.
The Rohingya Crisis as a Regional Security Concern
A primary concern for Bangladesh is the unresolved Rohingya crisis. For nearly a decade, Bangladesh has hosted more than 1.2 million refugees from Myanmar. This situation has created substantial economic and social challenges for the country.
The Rohingya Crisis Impact
=========================================
* Displaced Population: Over 1.2 million
* Primary Location: Cox's Bazar, Bangladesh
* Key Demands: Safe, voluntary, and dignified repatriation
* Security Implications: Human trafficking, border instability, radicalization
This crisis is more than a humanitarian issue; it is a significant regional security concern. The border regions between Bangladesh and Myanmar are unstable, characterized by transnational crime, human trafficking, and drug smuggling. Dhaka has repeatedly called on BIMSTEC members to help create the conditions necessary for the safe return of the refugees.
However, achieving a regional consensus remains difficult. Myanmar is a member of BIMSTEC, and its military government has shown little interest in facilitating repatriation. Other member states, including India, have often taken a cautious approach, balancing their humanitarian concerns with their strategic interests in Myanmar.
Cyber Threats and the Digital Divide
The security challenges in the Bay of Bengal extend beyond physical borders into the digital space. As regional economies become more connected, they face growing cyber threats. These include attacks on critical infrastructure and coordinated disinformation campaigns.
During the summit, Bangladesh highlighted the need for collective capacity-building in cybersecurity. The digital network is only as secure as its weakest link. If one nation lacks the resources to secure its systems, it can create vulnerabilities for the entire region. Consequently, Dhaka is advocating for a systematic exchange of technical expertise and best practices. This initiative aims to reduce disparities in cybersecurity capabilities and ensure that regional networks are better protected against sophisticated cyber threats.
Balancing Sovereignty with Cooperation
While Bangladesh supports closer security integration, it remains cautious about potential overreach. Brigadier General Islam noted that cooperative efforts must respect national sovereignty and be based on consensus. This perspective is shared by several smaller BIMSTEC members, who are wary of security arrangements that might favor the interests of larger states.
The success of BIMSTEC will depend on its ability to address these concerns. If the organization is seen primarily as an instrument for India's strategic ambitions, it may struggle to secure lasting commitment from its members. Conversely, if it can function as a genuine partnership that respects the sovereignty of all nations, it could become a key driver of stability in the region.
For Dhaka, the path forward involves maintaining this delicate balance. It must cooperate with India on critical security issues while defending its own interests and sovereignty.
