US Secretary of State Marco Rubio on Wednesday told lawmakers that the United States has assembled a coalition of more than 30 countries to secure global supplies of rare earth minerals, in a coordinated push to reduce dependence on China for resources critical to advanced manufacturing, clean energy and defence systems. The disclosure, made before the House Foreign Affairs Committee in Washington, frames supply-chain resilience as a central plank of the administration's foreign policy.

Key Developments

Rubio said the State Department recently convened a rare earths ministerial attended by ‘over 30-some-odd countries from around the world, all who were signing up for an American-led effort to ensure that critical supplies of rare earth minerals around the world are available for our emerging economies, and we don't remain overly dependent on China'.

He also flagged progress on a parallel initiative branded ‘Pax Silica', which he said now has 14 member countries cooperating to safeguard supply chains tied to artificial intelligence development. ‘These are 14 countries that are cooperating with one another to protect the supply chains critical to AI and AI development in the future,' Rubio said.

Why Rare Earths Matter

Rare earth minerals are embedded in electric vehicles, batteries, wind turbines, advanced electronics, semiconductors and defence platforms. China presently dominates large parts of the global rare-earth processing chain and remains a major supplier of critical minerals used across high-technology sectors, a concentration that has alarmed policymakers in Washington and allied capitals.

Concerns over concentrated supply chains have intensified in recent years, as export restrictions and geopolitical frictions exposed how thin the buffer is between industrial demand and a single dominant supplier.

What the Administration Said

Outlining what he described as the administration's foreign policy record over the past 16 to 17 months, Rubio repeatedly returned to efforts to counter Beijing's influence in strategic sectors, alongside diplomatic moves in Europe, the Middle East, Africa and Asia. He cast economic security, critical technologies and supply-chain resilience as core components of modern statecraft.

Rubio also pointed to stepped-up engagement with Pacific Island nations. ‘The Pacific Islands, small Pacific Islands, under constant pressure and threat from China, have received more attention from this administration than they received in the last 10 years combined,' he said.

Impact on India

For New Delhi, the rare-earths push carries direct strategic weight. India has been working to diversify supply chains and build domestic capacity in critical minerals as demand climbs across clean energy, electronics manufacturing and defence production.

The issue has also become a growing pillar of US-India economic and technology cooperation, with both sides exploring deeper collaboration in advanced manufacturing, semiconductors and resilient supply networks. Whether India formally joins the Rubio-led bloc, and on what terms, will be closely watched.

What Comes Next

The administration is expected to expand both the rare-earths coalition and the Pax Silica grouping in the coming months. The real test will be whether participating nations move from declarations to financed processing capacity outside China — the bottleneck that has frustrated every previous diversification attempt.
