The European Union has formally joined the US-led Pax Silica initiative, a multinational pact designed to secure the artificial intelligence and semiconductor supply chains that underpin modern technology.
The initiative launched in December 2025 with an initial roster of signatories that included Japan, South Korea, Singapore, Israel, Qatar, the UK, and the UAE. The EU, along with Germany, Greece, and the Netherlands, formally joined around June 23, 2026.
Since then, the coalition has continued to grow. Australia, Finland, Norway, the Philippines, and Sweden have all signed on.
The scope of Pax Silica covers the entire AI supply chain, including the mining of critical minerals, semiconductor fabrication, software development, and logistics. The pact emphasizes cooperation across critical minerals sourcing, energy infrastructure, advanced manufacturing, and AI development.
Pax Silica is a non-binding agreement. There’s no dedicated joint funding attached to it, and no mandates compelling member nations to take specific actions.
