Technology Transfer or Technology Theft? How Defence Agreements Shape Global Power—China vs India

In international politics, defence agreements are not merely contracts—they are instruments of power. The manner in which nations interpret, exploit, or respect these agreements often determines whether they rise as trusted partners or feared disruptors.


Few case studies illustrate this contrast better than China and India, two rising powers that started from comparable industrial baselines in the late Cold War era yet diverged sharply in how they used foreign military technology.

China chose strategic exploitation.India chose strategic restraint.


Both approaches produced results—but at very different costs.


Licensed Production: A Double-Edged Sword


Licensed production is designed as a controlled pathway:

  • The supplier shares manufacturing know-how

  • The recipient gains industrial depth

  • Intellectual property remains protected


In theory.


In practice, licensed production has become one of the most abused mechanisms in defence history.


China and the SU-27: From Licensee to Imitator


China’s agreement with Russia in the 1990s to manufacture the SU‑27 under license as the J-11 was supposed to be limited in scope.


Instead, it became a blueprint for industrial leapfrogging.


What China Did Differently


China:

  • Systematically disassembled imported kits

  • Mapped metallurgy, aerodynamics, and avionics

  • Integrated indigenous radar, sensors, and weapons

  • Gradually replaced Russian engines and electronics


The result was the J-11B, followed by the J-16, aircraft that retained Russian DNA but were functionally Chinese.

Russia protested. Contracts were violated. Trust collapsed.


But China had already achieved its objective.


Leapfrogging an Entire Aerospace Generation


By aggressively reverse-engineering foreign platforms, China compressed four decades of aerospace learning into less than twenty years.


This strategy enabled:

  • Indigenous AESA radars

  • High-thrust turbofan engines

  • Integrated sensor fusion

  • Rapid transition toward stealth platforms


Today, China is openly testing sixth-generation combat aircraft, something unthinkable without that early breach of trust.

Strategically, the gamble worked.


Diplomatically, the bill came later.


India and the SU-30MKI: Discipline Over Disruption


India’s experience with licensed production of the SU‑30MKI could not be more different.


India assembled and manufactured over 270 airframes—one of the largest licensed fighter production runs in the world.


Yet India:

  • Respected IP boundaries

  • Paid royalties consistently

  • Integrated upgrades transparently

  • Sought joint development rather than unilateral copying


This approach did not create a leapfrog—but it created something else.

Credibility.


The Cost of Playing by the Rules


India’s restraint had consequences:

  • Indigenous engines lagged

  • Radar and sensor maturity arrived late

  • Platform timelines stretched by decades


While China moved to next-generation systems, India often found itself catching up, forced to start R&D from first principles.

Strategically painful—but politically invaluable.


Trust as a Strategic Asset


In defence geopolitics, trust is currency.


India’s reputation as a rule-abiding partner enabled access that China never received.


The clearest example lies beneath the oceans.


Submarine Technology: Why Germany Trusted India, Not China


Germany has historically guarded its submarine propulsion technologies with extreme caution.


China was explicitly denied access due to fears of reverse engineering.


India, however, received technology transfer under Project-75, enabling indigenous submarine construction at Mazagon Dock Shipbuilders Limited.


This decision was not sentimental—it was strategic.


Germany trusted India not to copy, violate, or proliferate sensitive technology.


That trust cannot be reverse-engineered.


Sanctions, Policy Shocks, and Strategic Vulnerability


India’s rule-based approach comes with vulnerabilities:

  • Sanctions risk

  • Export control regimes

  • Political shifts in supplier nations


The same trust that enables collaboration also creates dependency choke points.

China eliminated this risk early—by burning bridges.


India accepted the risk—by preserving them.


Two Paths, Two Futures

China

India

Fast capability growth

Slower but sustainable growth

High sanctions risk

High trust quotient

Rapid leapfrogging

Long gestation cycles

Strategic suspicion

Strategic credibility

Neither path is morally pure.Neither path is strategically perfect.


The Emerging Middle Path


India is now attempting a hybrid strategy:

  • Co-development instead of licensing

  • Modular collaboration

  • Indigenous cores with foreign subsystems

  • Iron-clad contracts


This shift reflects a mature understanding:Trust alone is not power—but power without trust is brittle.


Conclusion: Power Is Not Just What You Build—It’s Who Trusts You


China chose speed over trust—and succeeded militarily, at a diplomatic cost.


India chose trust over speed—and paid in time, but gained strategic legitimacy.


As global defence cooperation enters an era of tighter controls and suspicion, India’s path may prove slower—but more survivable.


In the next article on Ambat Legal Insight, we will examine:

  • How treaty violations reshape international law

  • Why iron-clad defence agreements are now essential

  • And how nations are legally hardening technology transfer in response to China’s playbook


This is not just about aircraft or submarines.


It is about the future architecture of global power.
