EU signs Pax Silica Declaration on AI supply chains

The European Commission has signed the Pax Silica Declaration on behalf of the EU, joining an international initiative focused on AI security and resilient silicon supply chains.

Pax Silica is a US-led initiative that aims to strengthen cooperation among allies and trusted partners across the AI supply chain, from critical minerals and energy inputs to semiconductor manufacturing, AI infrastructure and logistics.

The Commission said secure access to silicon and related technologies is becoming increasingly important as AI reshapes economies, security and industrial competitiveness.

The declaration commits signatories to closer cooperation on trusted technology ecosystems and more resilient supply chains. It also aims to reduce strategic dependencies and improve coordination on the materials, infrastructure and manufacturing capacity needed for AI development.

The EU’s signature follows the adoption of the European Technological Sovereignty Package, which includes Chips Act 2.0 and measures to strengthen Europe’s capacity in semiconductors, AI, cloud and open-source technologies.

The Commission said participation in Pax Silica could support European businesses, strengthen international partnerships and contribute to Europe’s broader technological sovereignty objectives.

Why does it matter?

AI development depends on far more than models and software. Advanced chips, critical minerals, energy, manufacturing capacity, cloud infrastructure and logistics are becoming strategic layers of the AI economy. By joining Pax Silica, the EU is linking AI competitiveness and security to semiconductor supply-chain resilience and cooperation with trusted partners. The move also shows how digital sovereignty is increasingly pursued through both domestic capacity-building and selective international alignment.
