India joins U.S.-led Pax Silica tech alliance to boost secure supply chains, amid strengthened ties and trade deals.

India has joined the U.S.-led Pax Silica initiative, a coalition aimed at building secure, resilient technology supply chains among democratic allies, during an AI summit in New Delhi on February 20, 2026. The move marks a significant step in strengthening U.S.-India relations after tensions over India’s continued purchases of discounted Russian oil. The initiative, which includes Japan, South Korea, the U.K., and Israel, focuses on advancing cooperation in semiconductors, advanced manufacturing, and critical technologies to reduce reliance on China-dominated production networks. It aims to promote trusted, values-based supply chains and bolster innovation. India’s participation follows a recent trade agreement that reduced U.S. tariffs on Indian goods from 25% to 18% and lifted additional levies on Russian crude imports, signaling broader strategic alignment in technology, defense, and economic security.
