Beyond Border Tensions: How China and India Quietly Cooperate

On 31 August 2025, in the northern Chinese port city of Tianjin, something quietly consequential took place. Xi Jinping and Narendra Modi met for the first time in seven years. No maps were redrawn. No sovereignty claims withdrawn. Yet what emerged was more revealing than any treaty: a managed thaw driven not by affection, but by constraint. This is rivalry without rupture, competition without catastrophe, and mutual dependence disguised as strategic autonomy.

China-India cooperation: Beyond border tensions to economic interdependence
Economic ties bind even as territorial disputes persist: the paradox of modern great power rivalry
For two nuclear-armed rivals with an unresolved border dispute stretching nearly 3,500 kilometres, the August 2025 Tianjin meeting was no small gesture. Xi spoke of partnership rather than rivalry. Modi referred to an "atmosphere of peace and stability". Flights between the two countries, suspended since deadly clashes in 2020, were to resume. Yet this was also not a reconciliation. Instead, it was something subtler and more revealing: a managed thaw driven not by affection, but by constraint.

Why War Never Came

Since the brutal hand-to-hand fighting in the Galwan Valley in June 2020, which killed at least 20 Indian and 4 Chinese soldiers, many analysts predicted an inexorable slide toward confrontation. That prediction has not materialised. The reason is not goodwill. It is cost.

A border war in the Himalayas would be economically disruptive, militarily complex, diplomatically isolating and politically risky for both sides. China faces slowing growth, demographic decline and financial fragility. India confronts employment pressures, fiscal constraints and regional instability. Neither can afford a conflict that would frighten investors, fracture supply chains and invite external intervention.

THE COST OF CONFLICT

China's GDP growth has slowed to 5 percent whilst managing a debt-to-GDP ratio exceeding 280 percent. India must create 8 to 10 million jobs annually to absorb new labour market entrants. A prolonged border conflict would derail both economies' fundamental priorities: stability for China, employment for India.

Nuclear deterrence reinforces restraint. So does international scrutiny. But above all, mutual dependence, especially economic, has acted as a brake on escalation. The Tianjin meeting acknowledged this reality without celebrating it.

Trade Beneath the Tension

Even at the height of diplomatic frost, trade continued. In 2023 and 2024, China was India's largest trading partner, with bilateral commerce exceeding $118 billion. The imbalance is stark: China exports roughly $120 billion of goods to India annually, whilst India exports under $15 billion to China. Yet this imbalance also explains the resilience of ties.

SUPPLY CHAIN DEPENDENCE

Indian pharmaceuticals depend heavily on Chinese active pharmaceutical ingredients, with over 40 percent of inputs sourced from China. India is the world's largest supplier of generic medicines to the United States, but its supply chain runs through Chinese factories. Telecommunications equipment, industrial machinery, solar panels and lithium-ion batteries flow steadily from China into Indian manufacturing.

Attempts at full decoupling would raise costs for Indian producers and slow growth. India has tightened rules on Chinese investment, banned hundreds of Chinese mobile applications, and scrutinised technology firms. China has absorbed the restrictions without retaliation. The result is not disengagement, but selective insulation.

This is rivalry without rupture.

The Border as Theatre and Constraint

At the heart of mistrust lies the Line of Actual Control, the de facto border created after the 1962 war. It remains undefined, deliberately ambiguous, and periodically contested. China controls Aksai Chin, which India claims as part of Ladakh. China also claims Arunachal Pradesh, which it calls "South Tibet", whilst India administers it fully. Strategic considerations dominate: high-altitude vantage points, supply routes, religious symbolism and infrastructure connectivity.

The 2024 disengagement agreement did not resolve these disputes. It reduced risk. Patrols resumed. Buffer zones were adjusted. Monthly review mechanisms were reinstated. The objective was not peace, but predictability.

This was a tactical thaw, not a strategic shift. The border remains contested. But contestation need not mean confrontation.

Why the Timing Mattered

The timing of the Tianjin meeting was no accident. The Shanghai Cooperation Organisation summit offered a neutral multilateral setting. The BRICS meeting loomed. China sought diplomatic calm as it expanded influence in the Global South. India faced growing pressure from its business community to stabilise relations, particularly as American tariffs under Donald Trump began to bite.

THE TRUMP TARIFF SHOCK

In July 2025, the Trump administration imposed tariffs totalling 50 percent on Indian exports: half framed as "reciprocal", half as punishment for India's continued purchase of Russian oil. The move shocked Indian policymakers. For two decades, Washington had cultivated India as a strategic partner against China. Suddenly, the partnership appeared transactional. India's exports to the United States, valued at approximately $80 billion annually, faced severe headwinds. The shock accelerated New Delhi's recalibration.

As relations with Washington encountered turbulence, New Delhi adjusted. Not by abandoning the United States, but by rebalancing. Strategic autonomy, long India's guiding doctrine, reasserted itself. If Washington treated the partnership as conditional, India would diversify its options. The Tianjin meeting was one such diversification.

STRATEGIC AUTONOMY REASSERTED
Multi-Alignment as Survival Strategy

India's foreign policy has long rested on the principle of strategic autonomy: the refusal to align exclusively with any great power bloc. This principle, inherited from the Non-Aligned Movement, is not ideological romanticism. It is survival strategy.

India purchases defence equipment from Russia, participates in military exercises with the United States, engages economically with China, and coordinates diplomatically with the European Union. This multi-alignment allows India to extract benefits from multiple relationships without surrendering autonomy to any single partner.

The Trump tariffs reminded New Delhi why this approach matters. Dependencies are risks. Diversification is prudence. The Tianjin meeting was not betrayal of the West. It was insurance against Western unreliability.

Cooperation Without Trust

China and India cooperate most effectively where ideology is least relevant. They align in multilateral forums such as BRICS, the G20 and the Shanghai Cooperation Organisation. On climate negotiations, both resist binding targets imposed by advanced economies. On development finance, both argue for reform of global institutions. On trade, both push back against Western protectionism.

This cooperation is pragmatic, not sentimental. Neither side assumes benign intent from the other. But both recognise that obstructionism is costly.

Even religious diplomacy has re-emerged. In 2025, the Kailash Manasarovar pilgrimage, crossing Tibetan territory, resumed after a five-year pause. For Hindus, Mount Kailash holds profound spiritual significance as the abode of Lord Shiva. The pilgrimage requires Chinese permission to cross into Tibet. Its resumption signals limited confidence-building without altering sovereignty claims. India does not recognise Chinese control over Tibet; China does not relinquish it. Yet pilgrims cross the border, monks offer blessings, and diplomacy finds expression in ritual.

Cooperation without trust is still cooperation. The absence of affection does not preclude the presence of interest.

Competing for the Global South

China and India are not merely neighbours; they are aspirants to leadership of the Global South. China leverages capital. Through the Belt and Road Initiative, it finances ports, roads and power plants, often at scale, sometimes at risk. India leverages diplomacy. It positions itself as a convenor, a bridge-builder, and a voice for emerging economies in global forums.

BRI INVESTMENT SCALE

China's Belt and Road Initiative has committed over $1 trillion in infrastructure financing across more than 140 countries since 2013. Annual BRI-related investments peaked at approximately $200 billion in 2019 before moderating. India's international development assistance, by contrast, totals roughly $3 billion annually, concentrated in South Asia and East Africa. The financial asymmetry is vast.

Neither approach is universally trusted. Sri Lanka's debt crisis has made many wary of Chinese lending. Hambantota Port, financed by China and leased back to Chinese operators after Sri Lanka defaulted, became a symbol of "debt-trap diplomacy". India's limited fiscal capacity constrains its ability to match China's investment volumes. The Global South accepts support from both without necessarily granting allegiance to either.

Few developing countries see China or India as a benevolent leader. They see options. And in a multipolar world, options are power.


Military Asymmetry, Strategic Caution

Militarily, the asymmetry is stark. China's defence budget exceeds $230 billion; India's is roughly $75 billion. China's military modernisation has accelerated, with advances in air power, cyber capabilities, naval reach, and hypersonic weapons development. India remains the world's second-largest arms importer, dependent on foreign suppliers for critical platforms.

MILITARY EXPENDITURE COMPARISON (2024)

China: $230 billion (1.6% of GDP), world's second-largest military spender after the United States

India: $75 billion (2.4% of GDP), third-largest spender but limited modernisation capacity

Gap: China spends more than three times India's defence budget in absolute terms, though India spends a higher percentage of GDP

Yet this imbalance has not translated into adventurism. China's strategists understand that pushing India into a formal alliance with the United States would be counterproductive. India's strategists understand that overt alignment would constrain autonomy. Instead, India pursues multi-alignment: defence ties with the United States, energy and arms coordination with Russia, and engagement with China, all at once. China tolerates this ambiguity because the alternative is worse.

India participates in the Quad alongside the United States, Japan and Australia. It conducts joint military exercises with American forces. It purchases advanced surveillance drones and maritime patrol aircraft from Washington. Yet it also buys S-400 missile defence systems from Russia despite American sanctions threats, imports crude oil from Iran, and engages economically with China. This is not incoherence. It is calculated ambiguity.

Military asymmetry does not determine strategic outcomes when the weaker party has options and the stronger party has constraints.

A Rivalry That Is Managed, Not Resolved

The temptation is to frame China-India relations as a story of inevitable conflict. History offers little support for such determinism. What exists instead is a relationship shaped by geography, economics and restraint. Competition is real. Distrust is durable. But escalation is costly, and both sides know it.

The Tianjin meeting did not mark a new era of friendship. It marked something more important: mutual recognition that rivalry, left unmanaged, becomes self-defeating. Both countries benefit from stable borders. Both need predictable trade. Both seek influence in the Global South without triggering great-power confrontation.

This is not peace. It is balance. And in a fractured global order, balance may be the most stabilising force available.

The Lesson for the World

In an age of polarisation, the China-India relationship offers a counterintuitive lesson. Great powers do not always choose confrontation. Often, they choose coexistence: tense, transactional, imperfect, but functional.

The Western tendency is to view rivalry through the lens of the Cold War, where ideology hardened into existential opposition. But China and India are not ideological adversaries. They are status competitors with overlapping interests and incompatible territorial claims. They distrust each other profoundly yet depend on each other economically. They compete for influence yet coordinate in multilateral forums.

This pattern defies binary framings. It is neither alliance nor enmity. It is managed rivalry, a relationship that acknowledges competition without surrendering to it. Both sides recognise that unmanaged rivalry spirals into losses neither can afford.

The lesson is not that economics prevents war. It is that strategic calculation can override nationalist passion when leaders choose restraint over escalation.

The Tianjin meeting will not be remembered as a historic turning point. It will be remembered, if at all, as a tactical adjustment. But tactical adjustments matter. They signal intent. They manage expectations. They reduce the risk of miscalculation.

In a world where great power war would be catastrophic, the ability to manage rivalry without rupture is not a small achievement. It is statecraft.

IN BRIEF
Why China and India Cooperate Despite Rivalry

• Economic interdependence raises the cost of conflict (bilateral trade exceeds $118 billion)

• Neither can afford border war amidst domestic economic pressures

• Trump tariffs weakened India's reliance on US partnership, accelerating recalibration

• Multilateral forums (BRICS, SCO, G20) provide neutral ground for coordination

• Both compete for Global South influence but avoid zero-sum confrontation

• Military asymmetry does not translate into adventurism due to strategic constraints

• Strategic autonomy (India) and great power competition (China) both benefit from stability

• Managed rivalry is more stable than unmanaged confrontation
