The Galwan Valley clash of June 2020 marked a watershed in India–China relations. For the first time since 1975, soldiers on both sides lost their lives in a border confrontation, shattering a fragile equilibrium that had characterised the relationship for decades. Yet the Galwan episode was not an aberration — it was the violent expression of structural tensions that had been accumulating beneath the surface of diplomatic normalcy.
Structural Roots of Competition
The India–China rivalry is, at its core, a competition between two large civilisational states with overlapping spheres of strategic interest, contested borders, and divergent visions of the regional order. Unlike the Cold War's bipolar clarity, this rivalry operates in a complex multipolar environment where both countries are simultaneously competitors and participants in shared multilateral frameworks — most notably the Shanghai Cooperation Organisation and BRICS.
Three structural factors drive the competition. First, the unresolved border dispute across approximately 3,488 kilometres of the Line of Actual Control continues to generate periodic crises and militarisation. Second, China's growing strategic partnership with Pakistan — India's principal regional adversary — creates a structural encirclement dynamic that New Delhi views with deep concern. Third, Beijing's expanding presence in the Indian Ocean, through port investments, naval deployments, and economic relationships with littoral states, directly challenges India's conception of its primary strategic domain.
Power Transition and the Thucydides Problem
The structural realist framing of power transition theory helps illuminate one dimension of this rivalry. China's extraordinary economic and military rise over the past three decades has altered the regional balance of power in ways that India — itself a rising power — must navigate. The asymmetry is stark: China's GDP exceeds India's by a ratio of approximately 5:1, and its defence budget outpaces India's by a similar margin. Yet India's trajectory is upward, its democratic legitimacy serves as a form of soft power that Beijing cannot easily replicate, and its demographic dividend has yet to fully materialise.
What makes this rivalry particularly complex is that both states are, in different ways, revisionist with respect to the existing order — China more assertively so, India with greater ambiguity. India seeks to be recognised as a great power and a permanent member of the UN Security Council; China's ambitions extend to reshaping the normative architecture of the international system itself.
The Economics of Strategic Competition
The economic dimension of the rivalry has undergone a significant reconfiguration since 2020. New Delhi's ban on hundreds of Chinese mobile applications, restrictions on Chinese investment in sensitive sectors, and procurement exclusions from telecommunications infrastructure signal a deliberate strategy of partial decoupling. India has sought to position itself as an alternative manufacturing destination for companies diversifying supply chains away from China — a strategy that has yielded notable successes in electronics and pharmaceuticals.
Yet the economic relationship remains deeply asymmetric in China's favour. India's trade deficit with China has widened significantly, reflecting structural dependencies in intermediate goods, electronics components, and active pharmaceutical ingredients that cannot be reversed in the short term. This economic vulnerability complicates India's ability to adopt a more confrontational posture and creates domestic political tensions around the decoupling agenda.
Competing Architectures: The Multilateral Dimension
Both India and China are engaged in a parallel competition to shape regional and global multilateral architecture. China has championed the Belt and Road Initiative, the Asian Infrastructure Investment Bank, and the Regional Comprehensive Economic Partnership as instruments of its regional order-building agenda. India has responded with the Quad (alongside the United States, Japan, and Australia), bilateral security partnerships with Southeast Asian states, and its own connectivity initiatives — most notably the India-Middle East-Europe Economic Corridor announced at the G20 New Delhi Summit in 2023.
The competition for influence in South Asia — Nepal, Sri Lanka, Bangladesh, and the Maldives — represents a particularly active theatre of this strategic contest. China's economic presence in all four states has grown significantly, and its willingness to provide concessional financing without political conditionality has given Beijing leverage that India finds difficult to counter.
Strategic Implications for Regional Order
The India–China competition is not merely a bilateral affair — its outcomes will shape the strategic environment across the Indo-Pacific. A more assertive China that successfully consolidates its position on the border and marginalises Indian influence in South Asia would alter the regional balance in ways that concern Washington, Tokyo, Canberra, and the capitals of Southeast Asia. Conversely, a more confident India, strategically aligned with the democratic powers, would represent a significant counterweight to Chinese ambitions.
The challenge for Indian strategy is to navigate this competition without being instrumentalised by the United States in ways that foreclose India's strategic autonomy — a principle that remains deeply embedded in Indian strategic culture. New Delhi seeks a partnership of convenience with Washington and the Quad while maintaining its independent voice in multilateral fora and its relationships with Russia and the Global South.
This balancing act defines the central strategic challenge of India's foreign policy in the 2020s. Its outcome will determine not only the trajectory of the India–China relationship but the shape of the Asian order that emerges from the current period of geopolitical turbulence.
