US Unveils ‘Pax Silica’ Alliance to Secure Global AI Supply Chains Amid China’s Dominance
US launches “Pax Silica,” a global alliance with key allies to secure AI mineral supply chains and reduce dependence on China’s rare-earth dominance.
US announces the Pax Silica alliance to secure AI-critical mineral supply chains with global partners.
The United States on Thursday launched a new international pact aimed at securing critical mineral supply chains essential for artificial intelligence development, marking a strategic move to counter China’s rapidly expanding influence in the sector.
The initiative, named “Pax Silica”—a reference to silicon, the backbone of AI hardware—brings together key US allies including Japan, South Korea, Singapore, Australia and Israel. The partnership seeks to strengthen supply security for rare minerals and other resources vital for advanced AI technologies, reducing reliance on China, which currently controls nearly 70% of global rare earth mining.
According to the US State Department, Pax Silica is designed to unite countries that host major global technology firms and ensure “strategically aligned” supply systems instead of traditional “just-in-time” models. Washington says more nations are expected to join the framework.
Jacob Helberg, the US undersecretary for economic affairs, described the alliance as crucial for future competitiveness: “Pax Silica ultimately ensures that these countries have reliable access to the inputs and infrastructure that determine AI competitiveness.”
While the agreement does not yet outline detailed operational steps, it focuses on coordinated efforts to strengthen and secure timely supply flows among participating nations.
The move comes even as President Donald Trump recently announced that the US would resume allowing exports of Nvidia’s high-end AI chips to China—reversing former President Joe Biden’s national security–driven restrictions.
Several other countries, including the UAE, Canada, the Netherlands, and representatives from the European Union, attended the Washington meetings on supply chain cooperation, though they have not formally joined Pax Silica.
