US and allies sign San Francisco Declaration to protect AI supply chains from China

The United States and several allies have signed an agreement to draw up a joint list of critical technologies and supply chains behind artificial intelligence that need greater protection from China, the Financial Times reported, as summarised by Yahoo News. Japan, Australia, Israel, the United Kingdom, South Korea, India, Qatar and the United Arab Emirates signed the San Francisco Declaration on the Secure Foundations of Enduring Prosperity, according to Jacob Helberg, the US State Department's under secretary for economic affairs. Germany, Sweden, the Netherlands and the European Commission are expected to sign next week.

The declaration is part of Pax Silica, the US-led effort to secure AI supply chains, including critical minerals, The News reports. It says economic security is fundamental to national security, calls for stronger protection against theft or unauthorised transfer of technologies that could give hostile actors a military or intelligence edge, and sets up working groups on AI supply chain vulnerabilities and economic hubs to attract investment.

Helberg said the agreement would help countries identify sensitive technologies and infrastructure needed to build what President Trump has called "super intelligence." It comes days before Trump meets Chinese President Xi Jinping at the APEC summit in Shenzhen. Israel joined Pax Silica in December 2025.
