India and Japan Formalize AI, Chips, and Defense Economic Security Pact

India and Japan have elevated their bilateral relationship into a formal economic security partnership anchored by a $61 billion investment push covering AI, semiconductors, and shipbuilding, explicitly framed around reducing dependence on China. The agreement folds defense industrial cooperation into the economic partnership, creating durable structural incentives for reshoring and diversifying supply chains in both countries.

This is a structural supply-chain and defense-industrial realignment event, not a diplomatic statement — a committed $61 billion investment package changes where capacity gets built. Semiconductor and AI chip supply chains gain a new node outside China-adjacent risk, as both India and Japan direct capital toward domestic and bilateral fab and design capacity. Japanese shipbuilders and defense electronics firms gain an expanded market and co-development partner in India, which is the world's largest defense importer. Indian IT and semiconductor design firms gain Japanese technology transfer and capital, accelerating their climb up the value chain. Chinese suppliers and fabs lose prospective Indian and Japanese business that is now being deliberately redirected.
