A China-led Trilateral Nexus as India’s New Challenge

The Kunming Trilateral Nexus: A Blueprint for Encirclement or Strategic Posturing?

China’s coordination with Pakistan and Bangladesh, initiated through the Kunming Trilateral (June 2025), signifies a deliberate recalibration of South Asian geopolitics. Far from isolated diplomatic overtures, this is an evolving institutional framework targeting India’s regional strategic autonomy. At its core, the nexus is less about economic cooperation than about China’s calculated ambition to wield regional hegemony by encircling India.

Institutional Foundations Behind the Nexus

The Kunming Trilateral’s roots trace back decades. China’s historic alliance with Pakistan, forged in the aftermath of the 1962 Sino-Indian war, serves as a cornerstone of this nexus. The ties were financially enshrined as Pakistan’s debt to China surged to over $29 billion by late 2024, while military interdependence grew with 80% of Pakistan’s arms imports originating from Chinese suppliers. Moreover, China’s readiness to shield Pakistan at the United Nations—including instances where it blocked designations of Pakistan-linked terrorists—highlights strategic patronage that transcends economic calculations.

Bangladesh, meanwhile, represents a more recent realignment. China’s initial hesitation to embrace Bangladesh after the 1971 war gave way to cautious integration efforts under the Belt and Road Initiative (BRI). The Aman-25 naval exercises, Bangladesh’s participation in them, and growing cooperation in Chinese-led infrastructure projects signal a deeper embrace of China-Pakistan plus one strategies. With specific implications for maritime access via the Bay of Bengal, Beijing’s overtures to Dhaka are strategic, not just transactional.

Arguments and Evidence: How Does India Lose?

Encirclement Anxiety: Geopolitical encirclement becomes plausible as the Kunming Trilateral extends Chinese influence both militarily and economically in regions bordering India. The vulnerable Siliguri Corridor, infamous as India’s ‘Chicken’s Neck,’ stands particularly exposed to rapid mobilization scenarios in case of Sino-Pakistani cooperation. Additionally, the increased interoperability between Pakistani and Bangladeshi military installations, primarily using Chinese technology, compounds the strategic challenge.

Maritime Realignment: China’s naval diplomacy in the Bay of Bengal, leveraging Bangladesh’s ports and Pakistan’s Gwadar hub, positions Beijing to project consistent power across both the Indian Ocean and South Asia’s littorals. This undermines India's edge within the Indo-Pacific architecture, a concern flagged consistently by Quad policymakers post-Galwan (2020).

Erosion of Policy Platforms: Regional groupings like BIMSTEC and BBIN—primarily driven by India—face marginalization as China develops parallel mechanisms that exclude India. Much like SAARC’s decline due to India-Pakistan bilateral friction, the functional irrelevance of these initiatives could rise sharply amid growing trilateral cooperation.

Institutional Critique: The Hidden Faultlines

The consistent narrative from Beijing is that Kunming-type trilateral engagements aim at ‘peace and prosperity.’ However, this façade camouflages deeper structural tensions. For instance, while Pakistan's dependence on China's financial ecosystem illustrates a bilateral marriage of convenience, Bangladesh’s motivations are clearly distinct. Dhaka’s cooperation stems from its need for infrastructure financing, not ideological alignment with China. Drawing parallels with Hambantota (Sri Lanka), Bangladesh risks being caught in a debt-trap diplomacy that could erode its sovereignty and autonomy.

Critically, these alliances exploit gaps within India’s outreach mechanisms. Despite India’s promising energy corridor diplomacy in South Asia, its failure to scale infrastructural projects—owing to funding constraints and bureaucratic inertia—has ceded ground to China’s BRI. The Ministry of External Affairs claims significant traction from BIMSTEC initiatives, yet funding for regional connectivity projects between 2020–2024 averaged a mere ₹8,500 crore, compared to China’s $45 billion BRI down payment in South Asia.

Counter-Narratives and Their Limits

Advocates of the trilateral argue that India’s perceived overreach in South Asia catalyzed China’s Kunming diplomacy. Some analysts point to Bangladesh’s unease over India’s trade restrictions and infrastructure delays as spurred motivations for closer ties with China. Yet this position rings hollow. India’s targeted concessions post-2022 on water-sharing frameworks and trade facilitation agreements address many of Dhaka’s grievances.

Moreover, a counter-argument suggesting that Beijing may falter in its long-term ambitions merits consideration. Past BRI failures in Nepal, Sri Lanka, and Myanmar underscore both financial limitations and socio-political pushbacks against Chinese interventions. Bangladesh, which owes much of its policy flexibility to democratic institutions, will likely moderate its enthusiasm for heavy-handed Chinese financing.

An International Perspective: Germany’s Cooperative Federalism vs China's Regional Hegemony

What China calls cooperative regionalism, Germany would term hegemonic overreach. Germany’s EU-driven model of integration—a supranational framework that foregrounds mutual consensus and economic interdependence—offers a sharp contrast to China’s predatory bilateralism. Germany's multilateral agreements, encoded within EU institutions, distribute power while limiting unilateral recalibrations. China, by excluding India from its Kunming trilateral, adopts a coercive approach designed to centralize South Asian power dynamics under its influence rather than diffuse it.

Where Does This Leave India?

India’s response cannot rely solely on defensive posturing along vulnerable borders or reactionary rebuttals through trade barriers. Instead, it ought to pursue multidimensional strategies combining force projection, economic incentives, and regional coalition-building.

Realistically, India could triple its budget allocations for Northeast border infrastructure to ₹25,000 crore in 2025–2027 cycles while simultaneously capitalizing on its Quad alignments to fortify Bay of Bengal security frameworks. Diplomatically, India must re-engage Dhaka through innovative financing models for shared connectivity rather than emphasizing control-heavy agreements, which alienate partners. Militarily, India must increase asset interoperability with Quad allies to stymie Sino-Pakistani maritime integration.
