Bangladesh Looks East as India Water-Sharing Deadlock Drags Into Seventh Decade
Bangladesh is pushing ahead with an ambitious programme of dam and reservoir construction along its northern and eastern river systems — a strategic pivot that signals deepening frustration with India's failure to deliver a reliable water-sharing framework after nearly seven decades of bilateral negotiation.
The acceleration of these projects, substantially financed through Chinese infrastructure loans and technical partnerships, represents more than a response to seasonal flooding. It reflects a structural recalibration in how Dhaka is managing its long-term water security as climate variability intensifies and India's own upstream consumption grows.
The Ganges Compact and Its Limits
India and Bangladesh signed their first major water-sharing agreement for the Ganges at Farakka in 1977, a treaty that allocated flows between the two countries and established a Joint Committee to manage disputes. That framework was renewed in 1996 for an initial 30-year term and has since been extended, but officials in Dhaka describe its operation as increasingly inadequate to conditions on the ground.
The problem is not purely legal. Both countries have expanded their agricultural water demand substantially since the original compact was signed. India's construction of barrages and irrigation infrastructure upstream — including the Farakka Barrage itself — has altered the seasonal flow dynamics that Bangladesh's farmers depend on. During dry-season months, flows into Bangladesh's major distributaries have at times fallen below the thresholds the treaty was designed to guarantee.
Bangladesh's Ministry of Water Resources has repeatedly raised these concerns in Joint Committee sessions, requesting updated flow monitoring mechanisms and renegotiation of allocation thresholds to reflect changed hydrological conditions. Progress has been incremental. Several rounds of technical talks between 2020 and 2025 produced working-group reports but no binding revisions to the allocation formula.
Dhaka's patience, according to officials familiar with the negotiations who spoke on background, has thinned considerably. "The framework was designed for a different hydrological era," one official said. "We are not renegotiating out of hostility. We need instruments that function in the conditions we actually face."
China's Footprint in Dhaka's Water Architecture
Into this vacuum, Chinese state-linked construction firms and financing institutions have moved with notable speed. Projects that would have been tendered through international development institutions a decade ago are now routinely financed through a combination of Chinese EXIM bank credits, the Silk Road Fund, and direct bilateral aid packages managed through Beijing'samba economic corridor frameworks.
The projects Bangladesh has prioritised — including the long-discussed P upper Karnaphuli Reservoir and several run-of-river installations on eastern tributaries — are being built to compressed timelines. Chinese construction methodology, which typically bundles design, procurement, and civil works under a single contract, has delivered faster on-the-ground progress than the slower procurement cycles mandated by World Bank or Asian Development Bank financing agreements.
Beijing's interest in these projects is strategic but not purely altruistic. Each completed dam on a transboundary river gives China a degree of downstream leverage — a fact Dhaka's own water planners are aware of but have weighed against the more immediate problem of unreliable supply. "We have a bilateral dispute with India that is harming our agricultural output right now," one analyst at a Dhaka-based security think-tank said. "Chinese financing addresses this decade's problem. The next decade's problem is a separate conversation."
China's approach to South Asian water infrastructure has attracted scrutiny from Western analysts who note that Beijing has not signed the UN Watercourses Convention and has historically been reluctant to accept international frameworks governing shared river systems. In the Mekong basin, Chinese upstream dam operations have altered seasonal flow patterns affecting lower riparian states — a record that Indian policymakers cite when raising concerns about Dhaka's Chinese partnerships. Dhaka's position, articulated by senior water ministry officials, is that the operational realities differ: Bangladesh is not attempting to build dams on the Ganges proper but on eastern tributaries where Chinese upstream behaviour is not the relevant variable.
India's Regional Posture and the Cost of Inertia
New Delhi has taken note. India's Ministry of External Affairs has, in recent diplomatic exchanges with Bangladesh counterparts, expressed concern about the pace of Chinese involvement in sensitive water infrastructure — language that Dhaka has found both expected and somewhat beside the point. The core issue for Bangladesh is not geopolitics; it is irrigation supply during the dry season and flood attenuation during monsoonal peaks.
India's own water infrastructure programme has expanded significantly under its National River Linking Project, which proposes large-scale inter-basin transfers within India. Several components of that programme, if completed, would further alter the flow regimes entering Bangladesh. The Teesta River — where a bilateral sharing agreement has been under negotiation for over a decade without conclusion — is the most sensitive case. India built a barrage on the Teesta at Gazoldoba in 2019, a structure whose operational parameters Bangladesh was not consulted on in advance. That decision contributed to a marked cooling in the bilateral relationship at the official level.
India's strategic community is not uniform in its assessment. Former diplomats and regional security analysts who have worked on the Bangladesh relationship acknowledge that New Delhi's negotiating posture has often been driven by domestic political calculations in West Bengal — where any perceived concession on Teesta flows is politically toxic — rather than by a coherent subcontinental water policy. The result is that a framework nominally managed through the Joint Commission has in practice made little progress on the hardest cases, while smaller technical disputes accumulate into a broader atmosphere of distrust.
What Comes Next
The trajectory is not irreversible, but it is not neutral either. If Bangladesh completes its current slate of Chinese-financed projects within the next five to seven years, it will have substantially reduced its vulnerability to Indian water-sharing disputes — but also created new dependencies on Beijing. That dependency has a compounding quality: each completed project becomes a reference point for the next contract, and Chinese firms' ability to underbid on timeline and scope creates a self-reinforcing procurement dynamic.
For India, the cost of the current impasse is measured in regional standing, not just in water flows. Bangladesh is India's largest bilateral trade partner in South Asia and a critical buffer state on its eastern flank. A Dhaka that has genuinely viable alternatives to Indian infrastructure cooperation is a Dhaka that approaches the relationship from a position of increased leverage — one that Beijing will be attentive to cultivating.
The Joint Committee will meet again in the autumn. Officials on both sides expect no breakthrough on the core allocation questions, though both sides are likely to reaffirm the framework's continuing validity. What remains absent is any mechanism for updating the treaty in response to hydrological reality — and that absence is what is driving Dhaka to act on its own terms.
This publication's analysis differs from the wire framing primarily in foregrounding the structural conditions driving Bangladesh's strategic recalibration rather than presenting the shift as a straightforward geopolitical alignment with Beijing. The wire narrative treats Chinese financing as the primary variable; the analysis here suggests it is a response to the failure of existing frameworks — a distinction with significant implications for how India's policy community should understand what is at stake.
