India is joining the U.S.-led Pax Silica initiative, giving Washington its biggest win yet in the race to shape and influence who has access to advanced semiconductors and AI infrastructure supply chains.

Pax Silica is the Trump administration’s effort aimed at securing the global supply chain for silicon-based technologies. India joins Japan, South Korea, Singapore, the Netherlands, Israel, the United Kingdom, Australia, as well as Qatar and the UAE, as core members.

India’s participation, which will be formalized Thursday at the India AI Impact Summit in New Delhi, brings one of the world’s largest technology markets, and a member of the BRICS alliance, into Pax Silica at a moment when competition over AI hardware is intensifying across geopolitical blocs.

“Pax Silica is really not about China, it is about America. We want to secure our supply chains,” Jacob Helberg, U.S. undersecretary of State for economic affairs, told CNBC in an interview on Wednesday.

“We view India as a partner to help de-risk and diversify those supply chains,” Helberg added.
