EU joins Pax Silica declaration on AI and chip 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 seeks to strengthen cooperation among allies and trusted partners across the technologies needed to build and run AI systems.

The initiative looks beyond AI models and software. It covers the wider supply chain that makes AI possible, including critical minerals, energy inputs, semiconductor manufacturing, AI infrastructure, cloud capacity, and logistics.

Semiconductors are the advanced chips used to train and operate AI systems. They depend on complex supply chains, from raw materials and specialised equipment to chip design, fabrication, packaging, and deployment in data centres.

The Commission said secure access to silicon and related technologies is becoming more important as AI affects economic growth, security, and industrial competitiveness.

By signing the declaration, the EU commits to closer cooperation on trusted technology ecosystems and more resilient supply chains. The aim is to reduce strategic dependencies and improve coordination with partners on materials, manufacturing capacity, and infrastructure needed for AI development.

The move 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 wider technological sovereignty agenda.
