NEW DELHI — India and Japan announced a series of agreements on July 2, 2026, to deepen cooperation in defense, economic security, and maritime security. The agreements followed talks held on Thursday between Indian Prime Minister Narendra Modi and Japanese Prime Minister Sanae Takaichi in New Delhi.

Modi said India and Japan will collaborate on naval radio antenna systems and have adopted a joint road map on economic security. The leaders agreed to strengthen cooperation in artificial intelligence, shipbuilding, biogas, semiconductors, and critical technologies. "India and Japan view economic security as a shared security interest," Modi said.

Takaichi was in New Delhi for a three-day visit for the 16th annual India-Japan summit. She stated that New Delhi and Tokyo shared a commitment to Japan's initiative of a free and open Indo-Pacific based on freedom of navigation and respect for international law. "Expansion of maritime security cooperation is especially important for regional peace and stability," Takaichi said.

Japan is among India's largest foreign investors, having backed major infrastructure projects such as the Mumbai-Ahmedabad high-speed rail line. About 1,400 Japanese companies operate in India, with nearly half in manufacturing. Two-way trade between the nations reached $27.5 billion in India's 2025-26 fiscal year, and Japanese investment in India totaled $3.2 billion between April and December 2025.

The partnership builds on Modi's trip to Tokyo in 2025, during which Japan pledged to more than double its investment in India to over $61 billion in the subsequent decade. Both countries are members of the Quad, alongside the United States and Australia, which promotes cooperation on regional security, maritime issues, and defense.
