European Tech Sovereignty: EU joins US chip pact, France objects- What is the Pax Silica alliance and who are its members?
- Pax Silica is a US State Department-led multilateral initiative launched in Washington in December 2025 to coordinate AI chip supply chains and export controls. Original members are the UK, Japan, South Korea, India and Australia. The EU joined on 3 June 2026 committing $40bn in US chip purchases.Source: European Commission
- Why did the EU join the Pax Silica chip alliance?
- COREPER authorised EU accession on 3 June 2026 under pressure from the EU-US trade framework, which threatened automotive tariffs. Germany, Italy and the Netherlands backed the move; France opposed it on sovereignty grounds.Source: European Commission
- How does Pax Silica counter China's semiconductor ambitions?
- The alliance coordinates AI-chip export controls and procurement commitments among Allied Nations, collectively restricting which countries can access the most capable semiconductors and maintaining Western leading-edge chip advantages.
- Why did France oppose EU membership of the Pax Silica alliance?
- France cited digital sovereignty concerns and asked the Commission to clarify the Council's oversight role in the alliance. Critics characterised the accession as locking Europe into US chip dependency at the same moment it passed a cloud-sovereignty law.Source: European Commission
- How much did the EU commit to spending on US chips through Pax Silica?
- The EU committed to purchasing at least $40bn (€37bn) in US AI chips as part of the EU-US trade framework linked to Pax Silica membership, authorised by COREPER on 3 June 2026.Source: European Commission
Background
Pax Silica is the central geopolitical instrument in the global semiconductor contest. When the EU joined on 3 June 2026 via a COREPER authorisation committing the bloc to purchase at least $40bn (€37bn) in US AI chips, it entered a club already shaped without it. The alliance had launched in Washington in December 2025 under US State Department stewardship, and the UK, Japan, South Korea, India and Australia all joined before Brussels moved. France opposed the EU accession, citing sovereignty concerns; Germany, Italy and the Netherlands backed it. Council validation followed on 8 June.
The alliance's core function is to coordinate AI-chip supply chains and export controls among allies, a direct counter to China's bid to close the gap in advanced semiconductor manufacturing. By pooling procurement commitments and aligning export licences, members collectively shape who can access the most capable chips. For the EU the accession also doubles as a trade concession: the $40bn chip commitment sits inside the EU-US trade framework and signals Brussels would rather buy American silicon than face automotive tariffs.
The strategic tension Pax Silica exposes is the one that defines European tech policy in 2026: Europe adopted the Cloud and AI Development Act on the same afternoon it joined the alliance, asserting sovereignty where it has alternatives while accepting dependency where it does not. Europe makes no leading-edge AI accelerator, and its advancing volume fab at Dresden produces mature chips. The July 2026 AI Gigafactories funding call will test whether majority-European ownership means European hardware or a corporate wrapper around Nvidia silicon.
