Consider Teesta water sharing deal under ‘current circumstances’: Bangladesh FM post BJP’s Bengal win

What Happened

Following a change of government in West Bengal, Bangladesh's Foreign Minister publicly signalled that Dhaka cannot indefinitely await an India-Bangladesh Teesta water-sharing agreement.
Bangladesh's FM stated that the Teesta River Comprehensive Management and Restoration Project would be a central agenda item during an upcoming Beijing visit, positioning China as "an extremely important friend."
Dhaka emphasized it has its "own work to do" — indicating willingness to advance the China-backed river restoration project independently of any bilateral deal with India.
The West Bengal government change removes the state-level veto that had long blocked a Teesta agreement, yet Bangladesh is no longer certain India will translate this into a signed deal quickly.
India's position was further complicated by the Ganges Water Treaty of 1996, which is due to expire in late 2026 and whose renewal remains uncertain.

Teesta River: Geography and Basin States

The Teesta River originates from the Teesta Khangtse Glacier in the eastern Himalayas at an altitude above 5,400 metres. It flows for approximately 414 km total — roughly 305 km through India (Sikkim and West Bengal) and 109 km through Bangladesh — before joining the Jamuna River at Phulchhari Upazila. The Teesta is the largest river in Sikkim and the second largest in West Bengal.

The basin lies across Sikkim (72.43% of drainage area) and West Bengal (27.57%).
Total drainage area: approximately 12,540 sq. km across India and Bangladesh.
In Bangladesh, the river irrigates five northern districts, making it critical for dry-season agriculture.
The river is fed by Himalayan glaciers and snowmelt, making its flow highly seasonal.

Connection to this news: Bangladesh's dry-season agriculture depends on Teesta flows from December to May, a period when India's upstream usage — dominated by the Teesta Barrage at Gajoldoba in West Bengal — sharply reduces downstream volume. This seasonal shortage is the core of the dispute.

Water as a State Subject: India's Federal Constraint

Under Entry 17 of the State List (Schedule VII) of the Indian Constitution, water — including water supplies, irrigation, canals, drainage, and embankments — is a state subject. This means the Union government cannot unilaterally sign international agreements that alter a state's water allocation without the concerned state's consent in practice.

The constitutional position has meant West Bengal's approval has historically been necessary for any Teesta deal.
In 2011, a draft interim agreement was ready to be signed during a bilateral summit but was withdrawn at the last moment due to objections from the West Bengal Chief Minister.
The 1983 temporary arrangement gave Bangladesh 36% and India 39% of dry-season flows, with no formal treaty backing.
Bangladesh sought 50% of flows; India's central government had offered 37.5% in the 2011 draft.

Connection to this news: The political change in West Bengal now removes the most prominent state-level block. However, Bangladesh is signalling it will not wait indefinitely for New Delhi to translate this opportunity into a signed agreement.

The 1996 Ganga Water Treaty and Transboundary River Diplomacy

The Ganga Water Treaty (also called the Ganges Water Treaty) was signed in December 1996 for a 30-year term, governing the sharing of Ganga/Ganges flows at Farakka Barrage during the lean (dry) season. It is a landmark of bilateral water diplomacy between India and Bangladesh.

Treaty is set to expire in late 2026, adding urgency to the broader transboundary water negotiations.
India and Bangladesh share 54 transboundary rivers; only the Ganga has a formal water-sharing treaty.
The Teesta dispute has long been cited as a test case for whether India can manage multi-river basin agreements with downstream neighbours.
India reportedly floated revised terms for the Ganga treaty renewal that would offer Bangladesh a reduced share, citing climate-driven flow changes.

Connection to this news: With the Ganga Treaty expiring in 2026 and Teesta talks stalled for over a decade, Bangladesh is diversifying its options rather than relying on India as the sole development partner for its northern river basin.

China's Teesta River Project: Strategic Footprint

China formally entered the Teesta equation in 2019 when Bangladesh and PowerChina signed an agreement for the Teesta River Comprehensive Management and Restoration Project. China offered a $987 million loan in 2020 for a project that includes a 102-km embankment from the Teesta Barrage to Chilmari in Rangpur.

The project addresses irrigation, flood control, and river restoration in five Bangladesh districts.
India views Chinese infrastructure projects in Bangladesh — particularly near the Siliguri Corridor (Chicken's Neck) — as carrying strategic security implications.
The Siliguri Corridor is a narrow strip of land (roughly 22 km wide at its narrowest) connecting northeastern India to the rest of the country; the Teesta basin lies in proximity.
Bangladesh's current caretaker government has maintained the project as a development priority.

Connection to this news: Bangladesh's FM visiting Beijing to discuss Teesta while signalling impatience with India represents a concrete diplomatic shift — China is no longer merely a financial alternative but an active partner Dhaka is choosing to engage.
