India-Bangladesh Relations: Navigating CEPA, Connectivity, and Geopolitical Currents

Introduction: A Relationship at the Crossroads of Geoeconomics and Strategy

The intricate tapestry of India-Bangladesh relations was recently highlighted by a nuanced policy adjustment from New Delhi regarding a 2020 transshipment agreement. This agreement had been a landmark, granting Bangladesh unprecedented access to India’s land and sea ports for exporting goods to third countries like Nepal and Bhutan. However, citing significant logistical congestion and mounting pressure on its domestic infrastructure, India recalibrated the terms, prioritizing its own export surge. While rooted in sound economic pragmatism and the imperatives of the ‘Make in India’ initiative, this decision cannot be viewed in isolation. It is a microcosm of the complex geoeconomics at play, where national interests, regional commitments, and infrastructural realities intersect. This move underscores a maturing relationship where decisions are increasingly driven by a hard-nosed assessment of mutual benefit and national capacity, moving beyond purely historical sentiment.

Despite this recalibration, the overarching narrative remains one of extraordinary convergence and deepening integration. The relationship, often hailed as a “Shonali Adhyay” (Golden Chapter) and a model for South Asian neighborhood diplomacy, is on the cusp of a transformative leap. Both nations are intensely negotiating a landmark Comprehensive Economic Partnership Agreement (CEPA), an ambitious framework designed to catapult their economic ties into a new orbit. This forward momentum was further reinforced by a significant diplomatic agreement in late 2024, where both sides committed to operationalizing new cross-border rail and inland waterway routes, signaling an unwavering focus on a connectivity-driven future. This article provides a comprehensive analysis of the multifaceted India-Bangladesh relationship, examining its historical foundations, the pillars of contemporary cooperation, the persistent challenges, and the overarching strategic context defined by the growing influence of China and India’s ambition to solidify its role as the Net Security Provider in the vital Indian Ocean Region (IOR).

The Historical Bedrock: From Blood and Sacrifice to a Landmark Partnership

The genesis of the India-Bangladesh relationship is unlike any other, forged in the shared struggle and sacrifice of the 1971 Bangladesh Liberation War. India’s unequivocal diplomatic, military, and humanitarian support was the decisive factor in Bangladesh’s birth as an independent nation. This included sheltering nearly 10 million refugees and the direct intervention of the Indian Armed Forces, culminating in the surrender of Pakistani forces in Dhaka. This profound historical event created a deep reservoir of goodwill and a unique emotional connect. The formal architecture of the relationship was established with the signing of the 25-year Indo-Bangladesh Treaty of Friendship, Cooperation and Peace in March 1972. This treaty laid down the principles of mutual respect for sovereignty, non-interference, and extensive cooperation across all sectors.

However, the path has not been linear. The tragic assassination of Bangladesh’s founding father, Sheikh Mujibur Rahman, in 1975 ushered in a prolonged period of military rule and political instability. This phase witnessed a chilling of relations, with some regimes in Dhaka adopting a perceptibly anti-India stance, allowing insurgent groups from India’s Northeast to find safe havens on Bangladeshi soil. It was only with the return of a democratic government, particularly under the leadership of Prime Minister Sheikh Hasina, that the relationship was steered back towards its foundational spirit of trust and cooperation.

A monumental achievement that showcased the potential of this renewed partnership was the finalization and implementation of the Land Boundary Agreement (LBA) in 2015. This historic accord resolved one of the world’s most complex and protracted border disputes, involving the exchange of 162 enclaves (111 Indian enclaves in Bangladesh and 51 Bangladeshi enclaves in India). The seamless execution of the agreement, which required a constitutional amendment in India, granted citizenship and fundamental rights to over 50,000 previously stateless people, ending a humanitarian crisis that had festered for decades. In stark contrast, the inability to finalize the treaty on sharing the waters of the Teesta River remains a significant and persistent irritant. An agreement was drafted and agreed upon in 2011, but its signing has been held up due to steadfast opposition from the state government of West Bengal, which cites concerns over water scarcity in its northern districts. This impasse highlights the challenging interplay of federal politics in India’s foreign policy execution. Nevertheless, progress on other fronts, such as the 2022 Memorandum of Understanding (MoU) on the withdrawal of water from the common border river Kushiyara, demonstrates that incremental, pragmatic solutions to complex water-sharing issues are achievable.

Fun Fact: The India-Bangladesh border, at 4,096 kilometers, is the fifth-longest land border in the world. Due to the complex terrain of rivers, marshlands, and densely populated areas, it is also one of the most challenging to manage.

Pillars of Modern Cooperation: A Multi-Sectoral Symphony

The contemporary India-Bangladesh partnership is a vibrant and diversified enterprise, resting on several robust pillars that have transformed the regional landscape.

1. Economic and Commercial Ties: The Engine of Integration

The economic relationship is the central pillar and the primary driver of bilateral ties. Bangladesh stands as India’s largest trade partner in South Asia, while India is Bangladesh’s second-largest trade partner globally. Bilateral trade has witnessed a phenomenal surge, growing from around $9 billion in 2017-18 to over $18 billion in FY 2021-22, before moderating slightly to around $15.88 billion in FY 2022-23 due to global economic pressures. To unlock the full potential and address existing imbalances, both nations are in the advanced stages of negotiating the Comprehensive Economic Partnership Agreement (CEPA).

The CEPA represents a paradigm shift from the existing South Asian Free Trade Area (SAFTA) framework. It is a far more ambitious agreement aiming to create a truly integrated economic space. Key objectives include:

• Reducing the Trade Imbalance: The trade balance is heavily skewed in India’s favor. CEPA aims to facilitate greater market access for Bangladeshi goods by tackling Non-Tariff Barriers (NTBs), such as complex customs procedures, testing, and certification requirements (Sanitary and Phytosanitary - SPS/TBT measures).
• Deepening Value Chains: The agreement focuses on building resilient regional value chains in sectors like textiles, pharmaceuticals, leather, and agri-processing. This would allow raw materials from India to be processed in Bangladesh and exported globally, leveraging Bangladesh’s manufacturing strengths.
• Expanding to Services and Investment: CEPA will include chapters on trade in services, promoting investment, intellectual property rights, and digital trade, creating a modern and comprehensive economic architecture.

For Bangladesh, which is on track to graduate from its Least Developed Country (LDC) status in 2026, the CEPA is critical. LDC graduation will mean the loss of duty-free, quota-free access to many developed markets. The CEPA will provide a new framework for preferential market access in India and enhance its overall export competitiveness. For India, the CEPA is a strategic tool to economically integrate its landlocked North-Eastern states with the dynamic economy of Bangladesh, transforming a sensitive border into a zone of prosperity.

2. Connectivity: The New Currency of Diplomacy

Connectivity has become the mantra of the India-Bangladesh relationship, viewed as the ultimate enabler of economic growth and regional integration. The strategy is to create a seamless multi-modal network.

• Waterways: The Protocol on Inland Water Transit and Trade (PIWTT) is the cornerstone of this effort. This protocol allows Indian vessels to traverse Bangladesh’s extensive river systems to reach the North-Eastern states, and for bilateral trade between the two countries. The recent expansion to 10 routes and the inclusion of new ports of call have enhanced its effectiveness. The use of Bangladesh’s Ashuganj port for transshipping goods to Tripura, for instance, reduces transit time from over 1500 km by road to just a few hundred kilometers.
• Railways: Tremendous progress has been made in restoring the pre-1965 railway linkages that were severed after the 1965 Indo-Pak war. The landmark Agartala-Akhaura rail link, inaugurated in late 2023, is a game-changer, directly connecting Tripura’s railway network to Bangladesh’s, providing access to the Chittagong port. Popular passenger services like the Maitree Express (Dhaka-Kolkata), Bandhan Express (Khulna-Kolkata), and Mitali Express (New Jalpaiguri-Dhaka) are powerful symbols of the burgeoning people-to-people ties.
• Roadways and Bridges: The construction of the Maitri Setu (Friendship Bridge) over the Feni River, connecting Sabroom in Tripura with Ramgarh in Bangladesh, provides India’s Northeast with direct access to the Chittagong port, which is only 80 km away. While the ambitious BBIN (Bangladesh, Bhutan, India, Nepal) Motor Vehicles Agreement has been stalled due to Bhutan’s environmental concerns, India and Bangladesh are moving ahead bilaterally to operationalize its framework, which will allow for the seamless movement of cargo and passenger vehicles.
• Energy Connectivity: This is a new and highly promising frontier. The India-Bangladesh Friendship Pipeline, a 131.5 km pipeline to transport high-speed diesel from a marketing terminal in Siliguri, India to a depot in Parbatipur, Bangladesh, was inaugurated in 2023. This ensures a sustainable, reliable, and cost-effective supply of fuel to northern Bangladesh. Furthermore, Bangladesh currently imports over 1160 MW of electricity from India, and there are plans to create a regional energy grid that could eventually include hydropower from Nepal and Bhutan.

Mnemonic for Connectivity Pillars: To remember the key areas of connectivity cooperation, think of the acronym “WATER”: W - Waterways (PIWTT, Ashuganj Port) A - Airways (Air travel bubble, airport usage) T - Terrestrial (Roads like BBIN, Maitri Setu) E - Energy (Friendship Pipeline, Power Grid) R - Railways (Agartala-Akhaura, Express trains)

3. Security and Defence Cooperation: Building a Shield of Trust

Given the long and porous border, a robust security partnership is not just desirable but essential for regional stability.

• Counter-Terrorism: The government of Sheikh Hasina has maintained an unwavering zero-tolerance policy towards terrorism and extremism. This has been a strategic game-changer for India’s internal security. Bangladesh has systematically dismantled the networks of Indian Insurgent Groups (IIGs) from the Northeast, such as the United Liberation Front of Asom (ULFA), that had used its territory for decades. This cooperation is underpinned by real-time intelligence sharing between security agencies.
• Border Management: The Comprehensive Border Management Plan (CBMP) is in place to improve coordination. However, challenges persist. Cross-border smuggling of narcotics (especially Yaba tablets), cattle, and gold, along with human trafficking, remains a serious concern. The issue of border killings, or deaths of civilians during BSF operations, is a highly sensitive and emotional issue in Bangladesh. Both the Border Security Force (BSF) and Border Guard Bangladesh (BGB) are committed to bringing such incidents down to zero, with the BSF increasingly using non-lethal weapons.
• Defence Partnership: Defence ties have been significantly upgraded. This is institutionalized through annual joint exercises like SAMPRITI (Army) and BONGO SAGAR (Navy), and regular Coordinated Patrols (CORPATs). India has extended a $500 million Line of Credit (LoC) to Bangladesh for the procurement of defence equipment, which is aimed at helping Bangladesh diversify its military hardware and build its own defence industrial base. This cooperation is crucial for ensuring security in the Bay of Bengal.

Statistic Spotlight: The Bay of Bengal is a critical strategic waterway. It carries an estimated 40,000 ships and nearly a quarter of the world’s traded goods annually. Its security is paramount for the economic well-being of both India and Bangladesh.

The China Factor: A Strategic Tightrope Walk

No analysis of the India-Bangladesh relationship is complete without examining the pervasive influence of China. Beijing has emerged as Bangladesh’s largest trading partner and its single largest supplier of military hardware. As a key partner in China’s Belt and Road Initiative (BRI), Bangladesh has seen a massive influx of Chinese investment in its infrastructure.

Chinese state-owned companies are behind major projects like the Padma Bridge Rail Link and the Karnaphuli River Tunnel. Beijing is also heavily involved in upgrading Bangladesh’s port infrastructure. From a security perspective, China’s role is even more pronounced. It has supplied Bangladesh with a wide array of military equipment, including frigates, fighter aircraft, and, most notably, two Ming-class submarines in 2017. Plans for a Chinese-built submarine support base in Cox’s Bazar (BNS Sheikh Hasina) have further amplified strategic concerns in New Delhi, which views these developments as part of China’s broader “string of pearls” strategy to encircle India.

India’s response has been calibrated and competitive, not confrontational. It has doubled down on its own ‘Neighbourhood First’ and ‘Act East’ policies, accelerating the implementation of its projects. India’s development partnership model, which emphasizes concessional financing through Lines of Credit, grant assistance, capacity building, and a demand-driven approach, is presented as a more sustainable and transparent alternative to China’s often opaque, loan-heavy model. By leveraging deep-rooted cultural, linguistic, and historical ties, India positions itself as the natural, long-term, and reliable partner for Bangladesh. For its part, Bangladesh practices a pragmatic foreign policy of “friendship to all, malice towards none,” skillfully balancing its relationships with both Asian giants to maximize its developmental gains.

• GS Paper 3 (Economy & Security): The focus on connectivity, regional value chains (CEPA), and infrastructure directly links to the Indian Economy syllabus. The aspects of border management, counter-terrorism, and maritime security (Bay of Bengal) are central to the Internal Security syllabus.
• GS Paper 1 (Post-Independence History): The 1971 Liberation War and the subsequent evolution of the relationship are key parts of post-independence Indian history and foreign policy.

Future Outlook and Policy Relevance

The future of the India-Bangladesh relationship is poised for significant growth but will require astute management of challenges. The finalization of the CEPA will be a watershed moment, potentially creating a seamless economic space and unlocking immense commercial potential. However, the Teesta issue remains a major political stumbling block. Failure to resolve it could erode political capital and create space for other actors. The strategic competition with China will intensify, requiring India to be nimble, responsive, and consistent in its project delivery and diplomatic engagement. The long-term relevance of this partnership is immense; a stable, prosperous, and friendly Bangladesh is a prerequisite for the security and economic development of India’s eastern and northeastern regions and is central to India’s vision of a peaceful and integrated South Asia.
