Bangladesh’s Deepening Ties with Pakistan’s ISI: What It Means for India’s Eastern Security Calculus

For decades, India’s eastern frontier was seen as the quieter flank of its national security landscape — a border defined more by shared rivers, cultural overlap, and economic interdependence with Bangladesh than by the kind of adversarial tension that has long characterised the western border with Pakistan. That comfortable assumption is now being tested. Reports of a six-member delegation from Bangladesh’s Directorate General of Forces Intelligence travelling to Pakistan in mid-August, following a similar visit by its Director General to Islamabad just months into his tenure, point to a steadily deepening security and intelligence relationship between Dhaka and Islamabad. For India, this is not a development to be dismissed as routine diplomatic engagement between two sovereign nations. It carries real implications for the strategic environment along one of the country’s longest and most sensitive borders.

A Relationship Rebuilt on Shifting Ground

To understand why this matters, it helps to recall how unusual this warming has been, at least by the standards of the past half-century. Bangladesh’s very founding in 1971 was shaped by a bitter break from Pakistan, and for much of its post-independence history, Dhaka’s relationship with Islamabad remained distant, occasionally cordial but never close. That changed markedly following the fall of Sheikh Hasina’s government in August 2024, an event that reshaped Bangladesh’s political landscape and, by extension, its foreign policy orientation. Under the subsequent interim arrangement, Pakistan’s military and intelligence establishment reportedly found what one former Indian ambassador described as “exceptional outreach” into Bangladesh’s institutions — an opening that appears to have persisted even as Dhaka’s current leadership has tried to project a more pragmatic, balanced foreign policy image.

This is the context in which the recent DGFI visits to Pakistan should be read. They are not isolated incidents but part of a pattern: senior Bangladeshi military intelligence officials meeting with Pakistan Army officers and their ISI counterparts, delegations travelling back and forth, and a broader normalisation of security ties that would have seemed unlikely a few years ago.

Why This Matters for India

India’s stakes in this relationship are considerable, for several interlocking reasons. First, geography itself is unforgiving. Tripura, along with several other northeastern states, shares its longest border with Bangladesh, and this frontier has historically been vulnerable to infiltration routes, arms smuggling, and support networks for insurgent groups operating in India’s Northeast. A more permissive security environment in Dhaka, shaped by closer coordination with Pakistan’s intelligence apparatus, raises legitimate concerns about whether such vulnerabilities could be exploited more systematically than in the past.

Second, there is the question of strategic leverage. As analysts have pointed out, Bangladesh does not necessarily need to choose between India and Pakistan to benefit from closer ties with Islamabad. Rather, Pakistan offers Dhaka an additional strategic lever precisely at a moment when its relationship with New Delhi remains unsettled — a reminder that India’s regional partnerships cannot be taken for granted, particularly during periods of political transition in neighbouring capitals.

Third, this development does not exist in isolation from Bangladesh’s broader foreign policy recalibration, including its evolving proximity to China. A Sino-Pakistan axis finding renewed traction in Dhaka would represent a meaningful shift in the regional balance, one that could complicate India’s traditional assumption of natural primacy in its immediate neighbourhood.

A Measured, Not Alarmist, Response

None of this warrants panic or overreaction. Bangladesh remains a sovereign nation entitled to conduct its foreign relations as it sees fit, and India’s own relationship with Dhaka retains deep economic, cultural, and infrastructural interdependencies that neither side can easily unwind. Trade linkages, water-sharing arrangements, and connectivity projects continue to bind the two countries together in ways that a handful of intelligence-level visits cannot easily undo.

What this moment calls for instead is clear-eyed vigilance rather than alarm. India’s security establishment, particularly in border states like Tripura, would do well to treat this development as a signal to reinforce intelligence-sharing mechanisms, strengthen border surveillance infrastructure, and maintain close coordination between state police and central agencies — precisely the kind of institutional readiness that recent counter-terror operations elsewhere in the country have demonstrated can be effective when properly resourced.

At the diplomatic level, India’s response should be to continue investing in the relationship with Dhaka on its own merits — through trade, connectivity, and people-to-people ties — rather than allowing anxiety over Bangladesh’s Pakistan outreach to dictate a more defensive or transactional posture. Neighbourhood diplomacy rarely rewards reactive policymaking.

Ultimately, the deepening Dhaka-Islamabad security relationship is a reminder that India’s eastern periphery, long treated as relatively settled, now demands the same sustained strategic attention traditionally reserved for its western and northern borders. Adapting to that reality, calmly and systematically, will matter more than any single diplomatic gesture in the months ahead.
