"Shared rivers are not merely sources of water; they are instruments of diplomacy, development and strategic influence."
The proposed Teesta River Comprehensive Management and Restoration Project has re-emerged as an important geopolitical issue after Bangladesh Prime Minister Tarique Rahman secured Chinese assurances during his June 2026 visit to Beijing. Beyond river management, the project reflects the growing intersection of water security, regional diplomacy and strategic competition in South Asia.
Why is the Teesta Project significant?
China and Bangladesh have discussed Teesta's development since 2016, with the cooperation continuing across successive governments.
| Chinese Proposal | Key Features |
|---|---|
| River restoration | Dredging 140 million m³ of sediment |
| Land reclamation | 171 sq km reclaimed |
| Flood control | Repair of 110 km and construction of 124 km of embankments |
| Connectivity | 224 km road network |
| Inland transport | 82 jetty facilities |
| Environmental management | Riverbank erosion control, disaster reduction and ecological preservation |
The project focuses on Bangladesh's downstream stretch of the Teesta and therefore does not alter the river's upstream course inside India.
Objective:
Restore river flow → Reduce floods → Improve irrigation →
Enhance transport → Generate economic development
Why does Bangladesh seek such a project?
Northern Bangladesh depends heavily on the Teesta for agriculture.
Major beneficiary districts include:
- Nilphamari
- Rangpur
- Dinajpur
- Bogura
- Joypurhat
- Gaibandha
The principal challenge arises during the December-February dry season, when river discharge falls sharply, affecting irrigation for paddy and vegetable cultivation.
To address this, Bangladesh constructed the Teesta Barrage Irrigation Project (TBIP) in the 1990s, its largest irrigation scheme. However, reduced river flow has repeatedly affected its functioning, including the closure of barrage gates during low-flow periods.
Problem Cycle
Low winter discharge
↓
Reduced irrigation storage
↓
Lower agricultural productivity
↓
Economic losses in northern Bangladesh
Why is the Teesta equally important for India?
The Teesta originates from the Cholamu (Tso Lhamu) Lake in Sikkim before flowing through West Bengal into Bangladesh.
India utilises the river for:
- Hydropower generation through multiple projects in Sikkim.
- Irrigation via the Gajoldoba Barrage in West Bengal.
- Water supply for agriculture in West Bengal, Sikkim and Assam.
- Tourism and ecological conservation, including migratory bird habitats.
Thus, India also has significant developmental dependence on the river.
Why has the India-Bangladesh water-sharing agreement remained unresolved?
India and Bangladesh negotiated an interim Teesta water-sharing agreement around 2010-11.
However, the agreement was not signed during Prime Minister Manmohan Singh's 2011 Dhaka visit due to objections from the Government of West Bengal.
Joint Statement (2011): Both Prime Ministers agreed to conclude Teesta and Feni river agreements "on a fair and equitable basis" at the earliest.
Despite repeated discussions by former Prime Minister Sheikh Hasina with India, including renewed technical consultations in 2024, a final agreement has not materialised.
India also proposed financing nearly a US$1 billion Teesta management project inside Bangladesh before the political transition in Dhaka.
Why does China's involvement concern India?
The project extends beyond infrastructure into strategic geography.
| Indian Concern | Explanation |
|---|---|
| Strategic proximity | Project lies near the Siliguri Corridor ("Chicken's Neck"), India's narrow link with the Northeast. |
| Chinese presence | Long-term deployment of Chinese engineers and technical personnel near a sensitive region. |
| Strategic capability | POWERCHINA possesses expertise in large infrastructure with links to China's strategic sectors. |
Bangladesh, however, argues that it routinely undertakes international infrastructure projects involving foreign experts, citing examples such as:
- Ruppur Nuclear Power Plant (Russia and other foreign personnel)
- Padma Bridge constructed with Chinese assistance.
Broader implications
The Teesta issue illustrates multiple dimensions simultaneously:
- Water security and food security are closely interconnected.
- Transboundary rivers require cooperative basin-level management.
- Domestic federal politics can influence international treaty-making.
- Infrastructure projects increasingly carry geopolitical significance.
- China's expanding footprint in South Asia continues to reshape regional strategic dynamics.
Way Forward
- Conclude an equitable India-Bangladesh Teesta Water Sharing Agreement based on scientific assessment.
- Strengthen the Joint Rivers Commission for continuous basin management.
- Promote integrated river basin planning involving ecology, irrigation and disaster management.
- Increase data sharing on river flows and flood forecasting.
- Ensure transparency in third-country infrastructure projects to minimise strategic mistrust.
- Encourage trilateral cooperation where developmental interests converge without compromising sovereignty.
Conclusion
The Teesta is no longer merely a river-sharing dispute but a test of cooperative water governance, neighbourhood diplomacy and strategic balancing in South Asia. A sustainable solution lies in reconciling developmental needs with ecological sustainability while fostering mutual trust among regional stakeholders. As climate variability intensifies pressure on shared rivers, cooperative management will become indispensable for long-term regional stability.

Quick Q&A
What is the Teesta River Comprehensive Management and Restoration Project, and why has it emerged as a strategically significant issue in India-Bangladesh-China relations?
The Teesta River Comprehensive Management and Restoration Project is a large-scale river management, flood control, irrigation and regional development initiative proposed with Chinese assistance for Bangladesh. The proposal originated through a Memorandum of Understanding (MoU) signed in 2016 between Bangladesh and China's POWERCHINA and was revived in 2025 through an extension signed by the Bangladesh Water Development Board. The project includes dredging nearly 140 million cubic metres of sediment, reclaiming around 171 square kilometres of land, strengthening and constructing over 230 kilometres of embankments, developing more than 220 kilometres of roads and establishing multiple jetty facilities to improve inland connectivity and economic activity. Since the project lies entirely within Bangladesh as a lower riparian state, it focuses on utilizing the water currently flowing into Bangladesh rather than altering upstream flows. The significance of the project extends beyond water management. Economically, it seeks to reduce floods, prevent riverbank erosion, improve irrigation and stimulate development in northern Bangladesh. Strategically, China's participation introduces an important geopolitical dimension because the project area lies close to India's Siliguri Corridor, commonly known as the 'Chicken's Neck', a narrow stretch connecting mainland India with the North-East. India views extensive Chinese infrastructure and technical presence near this sensitive region with caution. Diplomatically, the project reflects Bangladesh's strategy of diversifying development partnerships while balancing relations with India and China. For UPSC, the issue integrates GS-II topics of neighbourhood relations, transboundary river governance, cooperative federalism, water diplomacy and India's Act East policy, while also linking with GS-III themes of disaster management, infrastructure development, environmental sustainability and strategic security.
Why has the sharing of Teesta River waters remained unresolved despite decades of negotiations between India and Bangladesh, and what factors have complicated the issue?
The Teesta water-sharing dispute remains unresolved because it combines hydrological constraints, domestic political considerations, federal dynamics, agricultural requirements and strategic concerns. Although India and Bangladesh negotiated an interim agreement around 2010-11, it was not finalized during Prime Minister Manmohan Singh's visit to Dhaka in 2011 due primarily to objections raised by the Government of West Bengal under Chief Minister Mamata Banerjee. Since water is a State subject under India's constitutional framework, the consent of affected States is politically and practically important, making river diplomacy more complex. Bangladesh argues that river flows decline sharply during the crucial winter irrigation season between December and February, affecting agriculture across northern districts such as Rangpur, Nilphamari and Dinajpur. India, on the other hand, depends on the Teesta for irrigation in West Bengal, hydroelectric generation in Sikkim and regional development. Multiple dams and barrages upstream, including the Gajoldoba Barrage, regulate water for domestic needs. Seasonal climate variability, glacier-fed river dynamics and increasing uncertainties due to climate change further complicate water availability. Diplomatic negotiations have continued through Joint River Commission meetings, bilateral summits and technical committees, yet political consensus has remained elusive. The dispute illustrates the challenge of reconciling national diplomacy with federal politics and competing developmental priorities. From Bangladesh's perspective, delayed agreements encourage exploration of alternative development partnerships, including China. For UPSC, the issue demonstrates the importance of cooperative federalism, hydro-diplomacy, international river law, climate adaptation and neighbourhood-first diplomacy. It also highlights how unresolved bilateral issues can create opportunities for external powers to expand their influence in South Asia.
How does the Teesta River influence the economic, environmental and strategic interests of both India and Bangladesh, and what lessons does it offer for transboundary river governance?
The Teesta River is a classic example of how a shared river simultaneously supports economic development, ecological sustainability and national security. Originating from the Cholamu (Tso Lhamu) Lake in Sikkim at an altitude of over 5,000 metres, the river flows through Sikkim and West Bengal before entering Bangladesh. In India, the river supports several hydroelectric projects, irrigation systems, tourism and biodiversity conservation. The Gajoldoba Barrage and multiple hydropower stations contribute significantly to regional electricity generation and agricultural productivity. In Bangladesh, the Teesta is the lifeline of northern districts where irrigation supports rice cultivation and vegetable farming. The Teesta Barrage Irrigation Project was developed to stabilize agricultural production in a region historically affected by floods followed by severe dry spells. However, reduced dry-season flows have affected irrigation potential and local livelihoods. Environmentally, the river sustains wetlands, migratory birds and fragile Himalayan ecosystems. Excessive sedimentation, erosion, changing rainfall patterns and glacier retreat have increased vulnerability to both floods and water scarcity. Strategically, Teesta demonstrates that rivers are not merely ecological resources but also instruments of diplomacy and regional cooperation. The challenge is to balance upstream developmental needs with downstream rights through equitable and reasonable utilization, data sharing, flood forecasting and integrated basin management. International experiences from the Mekong River Commission and the Indus Waters Treaty show that institutional mechanisms can reduce tensions even amid political differences. For UPSC, Teesta provides an excellent case study connecting GS-I geography, GS-II international relations, GS-III environment, disaster management and infrastructure planning while emphasizing sustainable and cooperative river basin governance.
Critically analyse China's growing involvement in the Teesta River project and assess its implications for India's neighbourhood policy and regional strategic environment.
China's involvement in the Teesta River project reflects the intersection of development cooperation and geopolitical competition in South Asia. Officially, the project is presented as a developmental initiative focusing on flood management, riverbank protection, land reclamation, irrigation, transport infrastructure and regional economic growth in Bangladesh. China's technical expertise in dam construction and river engineering makes it an attractive development partner. However, infrastructure projects undertaken by Chinese state-owned enterprises often carry broader strategic implications because they contribute to Beijing's expanding economic and diplomatic footprint. For India, concerns arise primarily because the project is located close to the strategically sensitive Siliguri Corridor, which connects mainland India to its North-Eastern States. A sustained presence of Chinese engineers, technicians and infrastructure companies near this corridor is viewed through a national security lens. At the same time, Bangladesh maintains that its engagement with China is driven by developmental needs rather than geopolitical alignment. Bangladesh has similarly cooperated with multiple international partners in projects such as the Ruppur Nuclear Power Plant and the Padma Bridge. Therefore, interpreting every Chinese investment solely through a security perspective would oversimplify Bangladesh's foreign policy, which traditionally seeks strategic autonomy by balancing major powers. India's response requires a nuanced approach that combines timely implementation of development projects, greater economic integration, enhanced connectivity, water-sharing progress and respect for Bangladesh's sovereign choices. Excessive securitization without addressing legitimate developmental concerns may weaken India's influence. For UPSC, this issue illustrates concepts such as the Neighbourhood First Policy, strategic competition in the Indo-Pacific, development diplomacy, soft power, regional connectivity and balancing national security with cooperative engagement.
How can the Teesta River dispute serve as a case study for understanding the challenges and opportunities of water diplomacy, cooperative federalism and regional cooperation in South Asia?
The Teesta River dispute represents one of South Asia's most instructive case studies on transboundary water governance because it combines domestic governance, international diplomacy, environmental sustainability and regional geopolitics. At the domestic level, India's experience demonstrates how cooperative federalism influences foreign policy. Although international negotiations are conducted by the Union Government, successful implementation often requires political consensus with States such as West Bengal, whose agricultural and developmental interests are directly affected. This constitutional reality explains why the proposed 2011 interim agreement could not be finalized despite bilateral political willingness. At the bilateral level, Bangladesh's demand for equitable dry-season water availability highlights the dependence of downstream countries on upstream river management. The issue affects irrigation, food security, rural livelihoods and climate resilience, making water-sharing a humanitarian and developmental concern rather than merely a diplomatic issue. Regionally, China's participation demonstrates how unresolved bilateral issues can invite external actors offering finance, infrastructure and technology. The case therefore underlines the strategic importance of proactive diplomacy, timely implementation of commitments and confidence-building measures. Sustainable solutions could include basin-wide scientific studies, real-time hydrological data sharing, integrated flood forecasting, climate-resilient infrastructure, joint river commissions with greater technical capacity and periodic review mechanisms. Comparative lessons may also be drawn from institutions such as the Indus Waters Treaty and the Mekong River Commission, which show that structured engagement can continue despite political disagreements. For UPSC, the Teesta dispute connects GS-II themes of international relations and federalism with GS-III topics of disaster management, agriculture, climate change and environmental governance, making it an ideal interdisciplinary case study for both Mains examination and the Personality Test.
