Pakistan's starkly contrasting responses to upstream water infrastructure built by India and China have drawn sharp scrutiny, with a new report arguing that Islamabad's stance on transboundary water security is shaped as much by strategic alignments as by genuine hydrological concerns. The report, published in Organiser, highlights a fundamental inconsistency: if upstream interventions threaten downstream interests, that principle should apply regardless of whether the upstream nation is India or China.

China's Dam on the Upper Indus

China has constructed a medium-scale dam on the Sengge Zangpo — the Tibetan name for the upper reaches of the Indus River — near Demchok in western Tibet, close to the Line of Actual Control (LAC) with Ladakh. According to the report, this structure diverts and regulates sections of the river for local hydropower generation while supporting infrastructure expansion in Tibet's Ngari prefecture. Reports of the project have reportedly been available for more than a decade.

The Chinese project sits upstream of both India and Pakistan and, according to the report, could have implications for seasonal water flows further downstream. Despite these potential strategic consequences, the development has not prompted any sustained diplomatic or political campaign from Islamabad.

Pakistan's Persistent Objections to Indian Projects

The contrast with Pakistan's posture toward Indian water projects is stark. Islamabad has repeatedly raised objections to Indian run-of-the-river hydropower projects and maintenance works on the Chenab and Jhelum rivers, alleging violations of the 1960 Indus Waters Treaty and describing such projects as direct threats to its agriculture and water security.

These objections have been pursued through multiple international mechanisms, including the World Bank and the Permanent Court of Arbitration. Pakistan has consistently accused India of violating the spirit of the treaty over hydropower projects on the western rivers — a campaign that has attracted significant international attention over the years.

The Silence on China's Upstream Activity

By contrast, China's project on the Sengge Zangpo has attracted little public criticism from Pakistan. The report notes the absence of major parliamentary debates, international legal initiatives, or official warnings comparable to those routinely issued against India over similar concerns. 'The absence of sustained public objections stands out, given Pakistan's dependence on the Indus River system,' the report stated.

This muted response, the report argues, has strengthened perceptions that Islamabad's water diplomacy is driven as much by geopolitical calculations as by concerns over actual water security.

The China-Pakistan Strategic Calculus

The report attributes the differing responses to the broader strategic relationship between Islamabad and Beijing. China serves as Pakistan's largest supplier of military equipment, a major investor through the China-Pakistan Economic Corridor (CPEC), and a consistent diplomatic backer in international forums. Publicly challenging Beijing over upstream water infrastructure, the report suggests, could complicate a relationship that remains central to Pakistan's strategic and economic interests.

This geopolitical dependency, critics argue, has effectively created a double standard — one where India faces sustained legal and diplomatic pressure over the Indus Waters Treaty, while China's upstream interventions on the same river system pass largely without comment. As South Asia's water security pressures intensify, the consistency of Pakistan's diplomatic positions is likely to face growing scrutiny.
