The Hundred Billion Trap: How India’s China Deficit Became a National Security Problem

This article is the second in a series looking back at India in 2025 across politics, governance, the economy, and the social, cultural, and communal landscape. Here international affairs observer Shama Rebecca Sarin digs into the nitty-gritty of trade transactions between China and India to point out how China’s strides in this sector is aggravating not only economic imbalances but is also developing as a security threat for India.

 

India’s trade ledger with China no longer reads like a routine economic statistic; it reads like a balance sheet of dependence. In FY25, goods worth barely about USD 14.2 billion left Indian ports for China, while imports from China surged to roughly USD 113 billion, pushing the bilateral trade deficit to an unprecedented about USD 99 billion. That single relationship now shapes India’s external accounts more than any other, even as tensions on the border and in multilateral forums harden.

 

The Making Of A Structural Imbalance

Two decades ago, the trade gap was a rounding error, well under USD 1 billion at the start of the century. By FY21, the deficit had swollen to a level in the mid‑40‑billion‑dollar range, only to more than double again in four years, touching about USD 99 billion in FY25 as imports climbed and exports actually fell. India now runs a healthy surplus with partners like the United States, but the China shortfall is so large it can overshadow those gains and distort the overall current account picture.

This explosion is not simply about buying more consumer goods; it reflects the way India plugged into global value chains. As manufacturing and infrastructure spending accelerated, Indian industry turned to China for cheaper, faster and often higher quality inputs, from chips to chemicals. The result is an asymmetric interdependence: India depends on Chinese factories to sustain growth, while China can treat India as just one of many markets.

 

Inside the Import Machine

Behind the headline numbers lies a stark pattern. Electronics, electrical machinery and telecom gear now form the single largest chunk of imports from China, together accounting for well over a third of the bill. Estimates suggest that India sources around 70% of its electronic components and sub assemblies from Chinese suppliers, a share that rises above 80–90% in smartphones, networking equipment and some consumer electronics. Every new factory line that assembles gadgets for export carries a hidden tag: “Powered by Chinese parts”.

Green energy imports tell a similar story. In FY25, India imported over 350 lakh solar photovoltaic modules from China, valued at roughly USD 1.7 billion, despite ambitious plans to build domestic capacity. Chinese firms also dominate supplies of lithium ion cells and battery components, with their share estimated at well over 70% of India’s imports in this category and in many segments above 75%. The same pattern holds in pharmaceuticals: for critical active pharmaceutical ingredients, especially antibiotics, India relies on China for 80–90% of its requirements; certain molecules see dependence as high as 95%. Far from being confined to cheap trinkets, dependence is deepest in the very sectors India identifies as strategic for its energy transition, health security and industrial upgrading.

 

Policy Slogans, Policy Outcomes

Successive governments have tried to square this circle with an assertive vocabulary: “Make in India”, Production Linked Incentive schemes, talk of “de risking” supply chains and tariff tweaks aimed at nurturing domestic industry. The PLI programmes alone span more than a dozen sectors with a budgeted outlay of about ₹2 lakh crore, backed by higher customs duties on solar hardware, electronics and some chemicals. Yet FY25 data tell an uncomfortable story: India’s exports to China actually fell about 14–15% even as imports grew, widening the deficit further and underscoring how limited policy impact has been so far.

Part of the problem lies in the design of incentives. Many PLI supported projects focus on final assembly, not the full supply chain. A smartphone “made” in India often arrives as a nearly complete knock down kit from China, with Indian plants adding labour and minor components; similar dynamics play out in solar modules and consumer electronics. The value captured domestically remains small, while China continues to earn the bulk of profits from higher tech components, machinery and materials. Tariffs and anti dumping duties, deployed without a coherent industrial strategy, sometimes simply reroute the same imports through third countries at higher cost.

 

Strategic Vulnerability in a Hostile Relationship

This economic structure would be worrying even between close allies; it is alarming between two rivals that face off along a disputed border and compete for influence across Asia. Analysts warn that India’s dependence on Chinese inputs in energy, health care and digital infrastructure gives Beijing potential leverage far beyond trade talks. In a crisis triggered by conflict, sanctions or internal shocks in China, disruptions in the flow of APIs, solar modules, batteries or power grid equipment could cascade quickly through Indian hospitals, factories and power plants.

Chinese industrial overcapacity compounds the problem. Heavily subsidised firms use aggressive pricing to dump steel, chemicals, EV components and solar equipment abroad, undercutting domestic producers and discouraging long term investment in competing facilities. In sectors where India is trying to scale up, from EVs to green hydrogen, cheap Chinese imports can win short term applause from consumers but lock in long term technological dependence and job losses. The viral social media graphic that understates imports in earlier years may look like a simple mistake, but it fits into a broader political comfort with glossing over how deep this vulnerability runs.

 

Toward a Genuine Reset

A serious course correction would treat the China deficit not as an embarrassing number to be explained away, but as an organising principle for economic strategy. One step is to set clear, time bound targets for reducing Chinese import shares in critical sectors, electronics, APIs, solar and batteries, paired with transparent road maps for domestic capacity, technology transfer and skills. Incentive schemes should reward local value addition and R&D, not mere assembly; firms hitting deeper localisation thresholds could receive higher benefits, while those stuck in screwdriver technology models see support taper off.

Externally, India will need a more active trade and investment diplomacy to build alternative sourcing hubs in Southeast Asia, Africa, Latin America and with trusted partners in the developed world. This could include long term contracts for critical minerals and components, co development of technology with allies, and careful use of investment from Chinese firms under strict security and data safeguards, where it accelerates genuine domestic capability. For an AIDEM story, the argument is not isolationism but de risking: India’s rise as a manufacturing and green energy power will ring hollow if the country remains locked into a hundred billion dollar deficit loop with China, and closing this loop is as much a matter of national security as it is of trade policy.
