The two Indo-Pacific democracies cast the deepening partnership as a hedge in a region increasingly shaped by China's rise. India and Japan pledged on July 2 to broaden their partnership across defense, advanced technology and economic security, using their annual leaders' summit in New Delhi to knit the two countries more closely together at a moment of strategic flux in Asia. Indian Prime Minister Narendra Modi hosted his Japanese counterpart, Sanae Takaichi, who was in India for the 16th edition of the annual meeting between the two governments. ## What the leaders agreed The two sides announced a series of steps to expand cooperation, [The Associated Press reported](https://abcnews.com/Business/wireStory/indias-modi-japans-takaichi-expand-defense-economic-security-134401908). On defense, Modi said India and Japan would work together on naval technology, including radio antenna systems for warships. The leaders adopted a joint road map on economic security — a term that covers protecting supply chains and sensitive technologies — and agreed to deepen collaboration in areas including artificial intelligence, semiconductors, shipbuilding and other critical technologies. The economic centerpiece was investment. Japanese private companies committed roughly $12.5 billion in new investment in India through a batch of cooperation agreements signed around the summit. That pledge builds on a broader target set a year earlier, when the two countries agreed to aim for about 10 trillion yen in Japanese private investment in India over a decade. The numbers underline how substantial the economic relationship has become. Two-way trade reached about $27.5 billion in India's 2025–26 fiscal year, [according to the Observer Research Foundation](https://www.orfonline.org/expert-speak/modi-takaichi-summit-deepening-india-japan-ties-in-a-changing-indo-pacific), a New Delhi think tank, even as both governments say there is room for the figure to grow. ## A partnership shaped by the region Neither leader framed the deals purely in bilateral terms. India and Japan are both members of the Quad grouping alongside the United States and Australia, and both have watched warily as China expands its economic and military weight across the Indo-Pacific. Strengthening ties on maritime security, resilient supply chains and critical technology serves, for both, as a way to diversify partnerships and reduce dependence on any single power. For Takaichi, who took office in Japan relatively recently, the visit was an early test of her government's approach to a partner Tokyo has increasingly treated as central to its Asia strategy. For Modi, closer alignment with Japan fits a long-running effort to attract foreign investment and technology while positioning India as a counterweight in the region. Both governments have been careful, however, to present the relationship as constructive rather than aimed at any particular country — a framing that reflects India's traditional reluctance to be drawn into formal blocs. ## What to watch Announcements of this kind are common at annual summits, and the harder question is how much of the pledged investment and cooperation materializes. Previous targets — including Japan's earlier commitments to pour tens of billions of dollars into Indian infrastructure and industry — have been fulfilled unevenly, and the latest pledges will be judged over years, not headlines. Still, the direction is clear. Two of Asia's largest democracies, facing a more contested regional order, are choosing to bind their economies and security interests more tightly together. Whether measured in trade figures, defense projects or the flow of Japanese capital into Indian factories, the New Delhi summit marked another step in a partnership that both governments increasingly see as strategic rather than merely commercial. ## Sources - [India's Modi and Japan's Takaichi expand defense and economic security ties](https://abcnews.com/Business/wireStory/indias-modi-japans-takaichi-expand-defense-economic-security-134401908) - [Modi-Takaichi Summit: Deepening India-Japan Ties in a Changing Indo-Pacific](https://www.orfonline.org/expert-speak/modi-takaichi-summit-deepening-india-japan-ties-in-a-changing-indo-pacific)
