In 2025, the traditional “big brother” dynamic—India’s long-standing dominant influence in South Asia—has been significantly disrupted. Under a new interim administration, Bangladesh is transitioning from a subordinate geopolitical position to a doctrine of “Strategic Assertiveness.”
This shift has transformed the geography of the region into a complex strategic contest. While India geographically surrounds Bangladesh on three sides, Bangladesh functions as the strategic connective corridor—or geopolitical fault line—between mainland India and its northeastern states, commonly referred to as the “Seven Sisters.”
Dhaka’s Strategic Assertiveness
The interim government in Dhaka, led by Chief Adviser Muhammad Yunus, has articulated that Bangladesh will no longer be a “passive corridor” for Indian interests.
This strategic recalibration is underpinned by key foundational security components. Foreign Affairs Adviser Touhid Hossein’s articulation of the “Strategic Fulcrum” doctrine marks a structural transformation in Bangladesh’s foreign and security policy.
This framework explicitly moves away from viewing India as the primary and uncontested regional partner. It recalibrates transit and connectivity arrangements—on which India heavily relies—transforming them from presumed privileges into active diplomatic instruments.
This strategic realignment positions Bangladesh as a balancing actor rather than a passive neighbour, leveraging its geographic centrality to negotiate from a position of strength and diversify its international engagements beyond traditional partners.
This recalibration is most visibly manifested in the military sector, where Dhaka is actively pursuing defence diversification to reduce long-standing alignments. The “Akash Bijoy-2025” air force exercises with Turkey and the exploration of formal maritime security links with Pakistan signify a deliberate and calculated engagement with non-traditional partners (The Diplomat, 2025).
Engagement with Islamabad, in particular, represents a significant turn given the historical context of 1971 and is interpreted as a direct strategic manoeuvre to counter what is perceived as India’s regional hegemony in its immediate neighbourhood, thereby asserting a more self-determined path.
The most sensitive diplomatic flashpoint remains the status of exiled Prime Minister Sheikh Hasina, who currently resides in India. Dhaka’s formal request for her extradition on serious allegations has emerged as a decisive turning point in bilateral relations.
This demand places New Delhi in a complex strategic dilemma, forcing a choice between legal cooperation and implicit protection. For Bangladesh, India’s response has become the crucial yardstick of mutual respect and trust, making the extradition issue the central diplomatic and strategic threshold defining the trajectory of relations in 2025, with implications extending far beyond the individual case.
The “Double-Lock” System
Geography in South Asia operates as a strategic instrument. The relationship between India’s Northeast and Bangladesh creates a unique condition of strategic entanglement. Bangladesh exists in a state of near-total land encirclement, sharing an extensive 4,096-kilometre border primarily with a single neighbour to its north, east and west.
This geography creates profound dependency, most acutely evident in the management of shared water resources. The two nations share 54 transboundary rivers, with India occupying the powerful position of hydrological gatekeeper for most, including major arteries such as the Ganges and Teesta.
This dynamic has enabled India to exercise significant “hydro-hegemony,” controlling water flows through structures like the Farakka Barrage to meet its own needs—historically resulting in severe water shortages and salinity intrusion downstream in Bangladesh.
This geographic containment also shapes Bangladesh’s economic access. Historically, bilateral commercial exchange has been robust, reaching approximately $15 billion in FY2024–25, with Bangladesh structurally integrated into Indian supply chains for essential raw materials, machinery and agricultural goods.
India remains one of Bangladesh’s largest trading partners, a relationship sustained by geography, cultural familiarity and critical multimodal connections that keep transaction costs low. However, this dependence represents a vulnerable interdependence.
Trade disputes and non-tariff barriers have periodically forced a diversion of Bangladeshi trade through slower and more expensive sea routes, increasing costs by up to 20 percent (Directorate General of Foreign Trade, 2025). The relationship remains structurally imbalanced, with Bangladesh consistently running a substantial trade deficit.
Notably, this sense of encirclement is mirrored in the geographic isolation of India’s own northeastern region.
The cluster of seven states is almost entirely cut off from the Indian mainland, bordered by China, Myanmar, Bhutan and Bangladesh. Its sole terrestrial link is the strategically critical Siliguri Corridor—a narrow strip of land just 20–22 kilometres wide, commonly referred to as the “Chicken’s Neck.”
This chokepoint renders the region highly susceptible to disruption and underscores its fundamental geographic dilemma—an “Achilles’ heel.”
Consequently, the Bangladesh–India relationship in this corridor is one of complex and volatile interdependence. For India, Bangladesh represents the most viable geopolitical bridgehead for connecting to and securing its northeastern states.
For Bangladesh, India remains an overwhelming geographic and economic reality. This structural bilateralism means political tensions—whether over water sharing or the extradition of former leaders—test the resilience of a partnership whose integration is effectively irreversible without imposing significant strategic and economic costs.
To counterbalance India’s “Neighbourhood First” dominance, Dhaka is seeking to revive SAARC, with Dr. Muhammad Yunus actively attempting to “breathe life” into the forum as a platform for broader multilateral engagement, including with Islamabad.
Simultaneously, by invoking the vulnerability of the “Chicken’s Neck” through calibrated rhetoric and public signalling, Bangladesh’s leadership aims to extract policy shifts on border killings and water-sharing, challenging India’s position as the region’s sole arbiter.
Connectivity as a Weapon
In 2025, the narrative of connectivity has shifted from “mutual development” to “strategic denial.” Chief Adviser Yunus’s framing of Bangladesh as the “only guardian of the ocean” for Northeast India represents a refined articulation of Dhaka’s evolving strategic autonomy.
This statement (The Daily Star, 2025), while described by Dhaka as having “honest intention,” recontextualises maritime access from a geographic reality into transactional leverage. It allows Bangladesh to recast connectivity on its own terms and justify diversifying strategic partnerships to advance its infrastructure and economic objectives. The recharacterisation of transit rights has thus emerged as the principal driver of Dhaka’s broader foreign policy pivot.
This realignment is exemplified by the architectural framing of a Bangladesh–China–Pakistan trilateral framework.
The platform prioritises multi-sectoral cooperation across trade, agrotechnology and maritime security, supported by a dedicated implementation task force. A central outcome of this alignment is the restoration of direct trade links with Pakistan, particularly through the newly launched Karachi–Chittagong maritime route, which significantly compresses transit timelines.
This development offers Dhaka a strategic alternative to its chronic $10 billion trade imbalance with India, especially following New Delhi’s protectionist restrictions on key Bangladeshi exports such as jute via land routes. It signals a multi-vector realignment of economic and diplomatic channels.
Simultaneously, Dhaka is recalibrating its engagement with major Indian-led initiatives to safeguard sovereign and economic interests. The proposed grouping with China and Pakistan is increasingly viewed as a potential alternative to the stalled SAARC, paralysed by India–Pakistan tensions.
Within this context, Bangladesh has adopted a “wait-and-watch” posture towards the Bangladesh–Bhutan–India–Nepal (BBIN) initiative and initiated a comprehensive audit of the Adani Power deal, as reported by The Economic Times (2025).
These moves form part of a coherent strategy to mitigate perceived overdependence on a single neighbour. While this recalibration enhances Dhaka’s bargaining power and partnership options, it also introduces new geopolitical variables affecting regional stability and long-term economic dependencies.
Bangladesh’s foreign policy shift prioritises strategic autonomy by diversifying partnerships away from India to mitigate structural dependency, notably through deepening ties with China and Pakistan (Kunming Trilateral, 2025).
It actively employs geographic leverage, treating maritime positioning as diplomatic capital to strengthen negotiations. Addressing trade asymmetries—such as seeking alternative routes like Karachi–Chittagong—aims to reduce dependence on India. According to the Ministry of Foreign Affairs (2025), while Dhaka maintains that this alignment is an “economic mechanism” rather than a “military bloc,” it is widely perceived as a “SAARC-minus-India” alternative.
Strategic Countermeasures
Both nations are now investing in infrastructure designed to bypass mutual dependencies. To reduce reliance on Bangladesh and secure the vulnerable “Chicken’s Neck,” India is implementing what analysts describe as a “Look-Away” policy.
This approach focuses on creating alternative supply routes and fortifying the region. A key initiative is the Kaladan Multi-Modal Transit Transport Project, which seeks to connect India’s northeastern states to the sea via Myanmar’s Sittwe port, bypassing Bangladesh entirely.
Concurrently, India is enhancing military preparedness by establishing new army garrisons near Kishanganj. This fortification is intended to shield the corridor from potential multi-front escalation, envisioned as a pincer scenario involving pressure from China in the north and a geopolitical wildcard—Bangladesh—in the south (Observer Research Foundation, 2025).
According to Bangladesh Sangbad Sangstha (2025), to alleviate perceptions of being “boxed in,” Dhaka is pursuing a sovereign maritime trajectory and defence diversification. A pivotal component of this reorientation is the development of the Matarbari Deep Sea Port with Japanese assistance, intended to position Bangladesh as a central node in Bay of Bengal commerce.
In parallel, Bangladesh is enhancing its naval and air capabilities through strategic acquisitions, including interest in JF-17 Block III fighter jets and the continued integration of Chinese submarines. These steps reflect a determined effort to build defence capacity capable of protecting sea lines of communication and projecting power in the Bay of Bengal.
The geopolitical trajectories of Bangladesh and India’s Northeast exist in a condition of inescapable mutual interdependence, creating a “Strategic Lock” in which comprehensive security is, by necessity, a cooperative endeavour.
India’s strategic leverage is constrained by acute geographic vulnerability at the Siliguri Corridor, where coercive pressure on Dhaka could risk isolating its northeastern states. At the same time, Bangladesh remains bound by the geopolitical gravity of its powerful neighbour. This enduring interlock ensures that while strategic postures may harden, outright disengagement remains an impractical and costly option for both sides.
