United States Hosts Second Pax Silica Summit in Washington, DC

Today marks the conclusion of the second Pax Silica Summit, held June 25-26 in Washington, DC. Launched by Under Secretary for Economic Affairs Jacob Helberg in December 2025, Pax Silica is the Department of State's flagship effort on artificial intelligence (AI) and supply chain security. The initiative aims to build a new economic security consensus among allies and trusted partners to advance secure, prosperous, and innovative supply chains spanning critical minerals, energy inputs, advanced manufacturing, semiconductors, AI infrastructure, and logistics.

The 2026 Pax Silica Summit added ten partners as signatories to the Pax Silica Declaration, increasing the total to 24 signatories in just six months and introducing new mechanisms to advance U.S. economic security.

The 2026 Pax Silica Summit also included industry participation, bringing together Pax Silica signatories and private sector representatives to discuss collaboration on securing AI supply chains. Over a dozen affiliate countries participated, further expanding the Pax Silica network of partners.
