India and Japan Strengthen Strategic Partnership with New Agreements on AI, Energy and Defence
India and Japan have signed a series of agreements to expand cooperation in artificial intelligence, energy, critical metals, defence, and economic security following talks between Prime Minister Narendra Modi and Japanese Prime Minister Sanae Takaichi in New Delhi. The leaders also agreed to prepare a joint roadmap on economic security, with Takaichi highlighting the importance of leveraging the strengths of both nations to build a more resilient and prosperous partnership amid global uncertainties.
The two countries adopted three key documents focused on economic security, energy resilience, and artificial intelligence. Prime Minister Modi said the combination of Japan’s precision technology and India’s software expertise would accelerate global AI development. India and Japan also signed their first defence co-development agreement, marking a significant milestone in bilateral defence cooperation and further strengthening collaboration within the Quad grouping.
Japan remains one of India’s largest investors, supporting major infrastructure projects such as the Mumbai-Ahmedabad high-speed rail corridor while expanding investments across Indian businesses. Bilateral trade between the two countries reached $27.5 billion during the 2025-26 fiscal year, and Japanese investments in India totalled $3.2 billion between April and December 2025. Takaichi, who is leading a large business delegation during her three-day visit, is also expected to engage with industry leaders to boost future economic collaboration.
