India and China aren't friends - but Nepal wants to unite them against climate threats

As the Himalayas warm at a pace outstripping the global average, the region’s climate hazards are evolving from a peripheral concern into a strategic imperative for the two Asian giants that dominate the range. India and China, whose 3,500‑kilometre frontier has been the theatre of wars, deadly clashes and a persistent military stand‑off along the Line of Actual Control, now face a shared threat that can sweep across borders without regard for political disputes. Nepal’s prime minister, Balendra Shah, seized the platform of the United Nations General Assembly in September to argue that the climate emergency could become a catalyst for cooperation, proposing a Himalayan Climate Resilience Mechanism that would bind the three nations in disaster response, data sharing and scientific collaboration. The proposal, while still nascent, raises a fundamental question: can the urgency of climate‑induced disasters override entrenched geopolitical rivalries, and what would such a shift mean for regional stability?

Climate Change as a Strategic Driver in the Himalayas

The Himalayas have entered a period of rapid environmental transformation. Recent observations indicate that temperatures in the mountain chain are rising faster than the global mean, accelerating glacier retreat, permafrost thaw and the formation of glacial lakes. A March report from the International Centre for Integrated Mountain Development noted that ice loss across the Hindu Kush Himalaya has doubled since 2000 compared with the 1974‑1999 period. On the Qinghai‑Tibet Plateau, glaciers have shrunk by roughly a quarter in area over the past six decades, according to Kang Shichang of the Chinese Academy of Sciences. The plateau now hosts more than 14,000 glacial lakes covering over 1,100 square kilometres, a figure that underscores the scale of the emerging flood risk.

These physical changes translate directly into heightened hazard exposure. Expanding glacial lakes increase the probability of outburst floods that can cascade downstream into Nepal, India and Bhutan. Landslide and rockfall risks are also intensifying; a 2024 American Geophysical Union study projected a significant rise in landslide hazards across the Himalayas and Tibet, with the greatest relative increase on the Tibetan Plateau. The convergence of these threats means that a single event—such as a debris flood—can have trans‑border consequences, threatening lives, infrastructure and livelihoods far beyond the immediate impact zone.

Nepal’s Diplomatic Initiative: The Himalayan Climate Resilience Mechanism

Prime Minister Shah’s appeal at the UN framed the Himalayas as a “laboratory of international cooperation rather than a frontier of fragmented information.” His proposal calls for a formal mechanism that would institutionalise cross‑border disaster response and facilitate the exchange of scientific data and expertise. While the details remain under development, a senior official from Nepal’s foreign ministry indicated that a preliminary framework is being drafted to build a common understanding among the three states. The proposal is deliberately broad, seeking to create a platform that can accommodate both emergency response coordination and longer‑term scientific collaboration, thereby addressing the immediate humanitarian need and the underlying data gaps that exacerbate risk.

Crucially, the mechanism would aim to overcome the current fragmentation of information that hampers effective response. For instance, the loss of hydrological data sharing—China stopped providing Brahmaputra data in June 2023 and India has not received Sutlej data since 2022—has left downstream nations without critical early‑warning capacity. By institutionalising data exchange, the mechanism could restore and expand the flow of information that is essential for flood forecasting, landslide risk mapping and coordinated evacuation efforts.

Historical Attempts at Sino‑Indian Climate Cooperation

India and China have a modest record of joint climate initiatives, largely confined to multilateral fora such as UN climate negotiations where both have aligned against Western emissions‑reduction demands. In 2009, the two countries signed an agreement to conduct joint research on glacier melt in the Himalayas and Tibet. The arrangement paired India’s Wadia Institute of Himalayan Geology with China’s Cold and Arid Regions Environmental and Engineering Research Institute. However, according to Dr. D.P. Dobhal, a retired glaciologist who led the Wadia Institute’s glaciology programme, the collaboration stalled after a single meeting, producing no tangible outcomes.

Since the early 2000s, limited data‑sharing agreements existed for the Brahmaputra and Sutlej rivers, but these have lapsed. India’s junior foreign minister Kirti Vardhan Singh disclosed in August 2025 that the agreements expired, noting that China ceased Brahmaputra data provision in 2023 and India has not received Sutlej data since 2022. China offered no public explanation for the 2023 cessation, and earlier interruptions—such as the 2017 halt during a military stand‑off—were attributed to “technical problems” at Tibetan monitoring stations. These episodes illustrate how geopolitical tension can quickly undermine even modest scientific cooperation.

Geopolitical Obstacles to a Tri‑National Climate Framework

The primary barrier to any substantive climate partnership lies in the dual‑use nature of the data and infrastructure involved. Hydrological and glaciological observations have clear civilian value for flood forecasting, yet the same data can inform military logistics, river‑crossing plans and strategic assessments of terrain stability. Walter Ladwig of the Royal United Services notes that information deemed essential by climate scientists may be perceived as strategic intelligence by national security establishments, especially where two militaries face each other across a contested frontier. This perception creates a security dilemma: sharing data can enhance disaster preparedness but also potentially expose vulnerabilities.

Moreover, the unresolved territorial disputes that span the LAC exacerbate mistrust. The line, though de facto, remains a flashpoint for stand‑offs and occasional skirmishes. Any formal mechanism that requires regular interaction between agencies in Delhi and Beijing would need to navigate a delicate balance between confidence‑building and safeguarding national security interests. Beijing’s historical caution, as highlighted by analyst William Yang of the International Crisis Group, suggests that even amid a recent thaw in high‑level engagement, the Chinese leadership will likely condition any major agreement on the broader context of border negotiations.

Potential Strategic Benefits of Cooperation

Despite these challenges, the strategic calculus for both India and China may evolve in response to the growing climate threat. A coordinated response to a major Himalayan disaster would mitigate humanitarian loss, reduce economic disruption and limit the political fallout that can amplify domestic criticism of government performance. For China, participation in a multilateral mechanism could reinforce its narrative as a responsible global power, complementing its broader Belt and Road Initiative (BRI) engagements in South Asia while avoiding the perception of unilateral dominance.

For India, re‑engaging with China on climate data could restore a pragmatic channel of communication that may spill over into other areas of bilateral tension. The resumption of data sharing on the Brahmaputra, for example, would improve flood forecasting for downstream Indian states, enhancing agricultural planning and disaster mitigation. Such functional cooperation could serve as a confidence‑building measure, gradually reducing the risk of miscalculation along the LAC.

Regional and Global Implications of a Himalayan Climate Mechanism

If Nepal’s proposal gains traction, the Himalayas could become a model for climate‑security cooperation in contested border zones worldwide. The mechanism would demonstrate that shared environmental risks can create a common security space, even where sovereign disputes persist. This would align with broader global trends where climate change is increasingly recognised as a “threat multiplier” that can exacerbate existing conflicts but also open avenues for joint action.

On a multilateral level, a successful Himalayan framework could feed into the UN climate architecture, offering a concrete example of sub‑regional cooperation that complements global mitigation efforts. It would also provide a platform for integrating scientific expertise from the region’s leading research institutions, such as the Chinese Academy of Sciences’ Institute of Mountain Hazards and Environment and India’s Wadia Institute, thereby enriching the global knowledge base on high‑altitude climate impacts.

Outlook: From Proposal to Policy

At present, neither India nor China has formally responded to Nepal’s overture, and the mechanism remains in the conceptual stage. The pace of progress will hinge on several variables: the willingness of Beijing and New Delhi to separate climate data from security concerns; the ability of Nepal to act as a neutral convenor that can broker technical protocols acceptable to both sides; and the broader diplomatic climate, including any escalation or de‑escalation of border tensions.

Analysts such as William Yang caution that Beijing’s caution is likely to persist until the border dispute sees substantive movement. Nonetheless, the “recent thaw” in high‑level political engagement and the practical necessity of addressing increasingly frequent debris floods—like the catastrophic event in August that prompted Shah’s UN address—provide a window of opportunity. Should the three governments manage to translate the Himalayan Climate Resilience Mechanism from proposal to policy, the region could witness a rare instance where climate imperatives reshape the strategic calculus of two rival powers, fostering a limited but meaningful arena of cooperation that may, over time, contribute to broader confidence‑building and stability in the Indo‑Pacific.
