Pax Silica Explained: Why India Was Left Out of the US Critical Minerals and AI Alliance

Pax Silica shows how the US is reshaping the AI supply chain—and why India is not yet seen as a full-stack technology partner.

Introduction:

Pax Silica is a US-led AI and semiconductor alliance—and India’s exclusion shows it is not yet seen as a full-stack AI supply chain power. However, India has been excluded from the inaugural group—despite ongoing US–India cooperation on critical minerals and emerging technologies.

Pax Silica brings together eight US allies—Japan, South Korea, Singapore, the Netherlands, the United Kingdom, Israel, the United Arab Emirates, and Australia—countries that already control key parts of the global AI and semiconductor ecosystem.

India’s absence raises a key question: Why was India left out of a US-led alliance focused on critical minerals and advanced technology?

5 Key Takeaways

  1. Pax Silica is a US-led effort to secure the full AI and silicon supply chain.
  2. The alliance focuses on trusted alternatives to China-centric supply chains.
  3. Members control advanced chips, AI infrastructure, and mineral refining.
  4. India cooperates with the US on minerals but lacks end-to-end AI production.
  5. India is seen as a future partner—not yet a core AI supply chain power.

What Is Pax Silica?

According to the US State Department, Pax Silica covers the entire silicon value chain, including:

  • Critical minerals and energy inputs
  • Semiconductor manufacturing and equipment
  • Advanced chip packaging and memory
  • AI data centers and infrastructure
  • Global logistics and supply chain security

The goal is to ensure that AI-critical technologies remain within trusted, aligned nations, reducing dependence on China and other high-risk suppliers.

Why These Eight Countries Chosen

Each Pax Silica member plays a critical role in today’s AI and semiconductor ecosystem:

  • Japan: Advanced materials, chip tools, and memory technology
  • South Korea: Global leaders in DRAM, NAND, and advanced fabs
  • Netherlands: Home to ASML, the world’s most important chip equipment firm
  • Singapore: Semiconductor manufacturing and global logistics hub
  • United Kingdom: Strong AI research and chip IP ecosystem
  • Israel: AI chips, semiconductor R&D, and defense technology
  • UAE: Capital, energy security, and AI infrastructure investment
  • Australia: Key supplier of lithium and rare earth minerals

Together, these nations host the most critical companies powering the global AI supply chain.

Pax Silica’s Real Objective: Reducing Dependence on China

Pax Silica is a strategic response to what the US calls “coercive dependencies” in global supply chains.

China dominates:

  • Mineral refining
  • Battery materials
  • Parts of semiconductor packaging

By aligning mineral-rich countries with chipmaking and AI infrastructure leaders, the US aims to build a trusted economic order for the AI era.

Why India Was Left Out

India’s exclusion is notable because critical minerals are now a major pillar of US–India ties.

In 2024, both countries signed a Memorandum of Understanding (MoU) on critical minerals, aimed at strengthening supply chain resilience. India is also a key partner under the Initiative on Critical and Emerging Technologies (iCET).

However, Pax Silica focuses on immediate, scalable AI production capability, not long-term potential.

The Core Issue: End-to-End AI Supply Chain Control

India currently lacks:

  • Advanced-node semiconductor fabs
  • Large-scale AI compute infrastructure
  • Critical mineral refining capacity
  • Global chip equipment suppliers

By contrast, every Pax Silica member already controls at least one irreplaceable layer of the AI production stack.

India’s Strengths—and Its Gaps

Strengths

  • World-class semiconductor design talent
  • Strong software and AI services ecosystem
  • Growing electronics manufacturing base
  • Strategic alignment with the US and allies

India’s Gaps

  • Limited advanced chip manufacturing
  • Dependence on imported refined minerals
  • Early-stage semiconductor fabrication
  • Smaller role in AI hardware production

These gaps explain why India is not yet seen as a core AI supply chain anchor.

A Signal, Not a Diplomatic Snub

India’s absence from Pax Silica should be viewed as a strategic signal, not a rejection.

The US appears to be drawing a line between:

  • Mineral cooperation partners (where India fits)
  • Advanced AI production leaders (where India is still emerging)

This mirrors Washington’s broader approach of forming small, high-trust technology blocs before expanding them.

What India Must Do to Join Future AI Alliances

To become indispensable to alliances like Pax Silica, India must:

  1. Accelerate semiconductor fabs beyond assembly and testing
  2. Build domestic mineral refining and processing capacity
  3. Scale AI data centers and compute infrastructure
  4. Attract global chip equipment and materials firms
  5. Move faster from policy announcements to execution

The Bigger Picture: The AI Supply Chain Is Fragmenting

The era of open, globalized tech supply chains is ending.

The AI age will be defined by:

  • Trusted alliances
  • Strategic minerals
  • Controlled chip manufacturing
  • Secure AI infrastructure

Countries outside these inner circles risk becoming technology consumers, not producers.

Our Take: What Pax Silica Really Signals

Pax Silica is less about exclusion and more about capability-first alignment. The US is prioritising partners that already control decisive layers of the AI stack—chips, tools, capital, and minerals—because AI supply chains reward speed and scale, not potential alone.

India’s absence reflects execution gaps, not strategic distance. If New Delhi accelerates advanced fabs, mineral refining, and AI compute at scale, entry into future Pax Silica expansions looks plausible. Until then, India remains a strategic partner-in-waiting, not a core node.

Conclusion

Pax Silica shows the AI race is no longer about intent—it is about execution.

India remains a key US partner on critical minerals and emerging technologies, but it is not yet seen as a full-stack AI supply chain power.

The next few years will determine whether India stays on the sidelines—or becomes central to the world’s most important technology alliances.
