New Delhi and Tokyo have moved well beyond diplomatic pleasantries. At the 16th annual India-Japan Summit, Prime Minister Narendra Modi and his Japanese counterpart Sanae Takaichi signed off on a dense architecture of bilateral commitments spanning defence co-development, artificial intelligence, energy resilience, pharmaceutical supply chains, and a joint economic security roadmap \u2014 all calibrated, without naming it, against the structural challenge posed by China’s regional dominance.<\/p>\n<\/p>\n
Takaichi, on her first visit to India since assuming the premiership, arrived with a high-powered business delegation. The symbolism was deliberate: this was not a courtesy call but a working summit with measurable deliverables, set against a global order that both leaders described, in notably convergent language, as facing “growing uncertainty.”<\/p>\n<\/p>\n
Modi drew directly from his remarks at last month’s G7 Summit, describing mutual trust as “the greatest strategic asset” in an uncertain environment, and positioning the India-Japan partnership as a proof of concept for that principle. Takaichi reinforced the framing, calling for both nations to “leverage our respective strengths to become stronger and more prosperous together” amid what she characterised as “international affairs in disarray.”<\/p>\n<\/p>\n
The joint statement registered “serious concern” over conditions in the East China Sea and South China Sea, opposing unilateral actions that endanger freedom of navigation and any attempt to alter the status quo by force. Takaichi’s updated Free and Open Indo-Pacific policy was explicitly aligned with India’s MAHASAGAR vision \u2014 a convergence that signals coordinated strategic positioning across the Indo-Pacific rather than parallel but disconnected postures.<\/p>\n<\/p>\n
Under Takaichi’s leadership, Japan has systematically deepened ties with what Tokyo terms “like-minded partners” \u2014 India, Australia, South Korea \u2014 as Beijing’s assertiveness across maritime and economic domains intensifies. The India summit fits squarely within that architecture.<\/p>\n<\/p>\n
The most technically significant defence outcome was the conclusion of an agreement for the Unicorn project<\/strong> \u2014 the Unified Complex Radio Antenna \u2014 between state-run companies from both sides. The agreement covers technology transfer and envisages the joint development of a radio antenna system for Indian warships, with officials indicating it will open pathways to co-developing air, land, and sea systems, including unmanned vehicles.<\/p>\n<\/p>\n Beyond Unicorn, the two sides agreed to expand bilateral military exercises, deepen maritime domain awareness through satellite capabilities, and strengthen cooperation in naval maintenance, repair, and overhaul. Both prime ministers directed their foreign and defence ministers to convene the fourth round of the 2+2 ministerial dialogue in Tokyo before year-end \u2014 a structural mechanism that keeps the defence relationship on a predictable escalatory track rather than subject to summit-to-summit momentum.<\/p>\n<\/p>\n The centrepiece of the economic agenda was the Joint Declaration on Economic Security<\/strong>, a project-based framework for building joint resilience across semiconductors, critical minerals, information and communication technology, clean energy, and pharmaceuticals. The declaration encompasses both government-to-government and business-to-business collaboration, recognising that supply chain vulnerabilities operate at the firm level as much as the state level.<\/p>\n<\/p>\n Both sides expressed “grave concerns” over economic coercion and non-market practices \u2014 specifically, “arbitrary export restrictions” that disrupt critical mineral supply chains. The reference to China’s dominance in pharmaceutical intermediates was unmistakable: India and Japan agreed to explore alternative supply chains for Active Pharmaceutical Ingredients (APIs)<\/strong> and Key Starting Materials (KSMs)<\/strong>, conduct a joint vulnerability analysis, and develop cooperation mechanisms to secure stable supply.<\/p>\n<\/p>\n The semiconductor dimension is equally pointed. India’s ambitions to build domestic fabrication capacity and Japan’s established strengths in materials and equipment create a complementarity that the roadmap is designed to institutionalise, rather than leave to market forces alone.<\/p>\n<\/p>\n The Joint Statement on Energy Resilience<\/strong> covers strategic stockpiling and reserve mechanisms for crude oil and petroleum products, and promotes joint investments across the maritime energy transport value chain \u2014 a supply chain dimension that extends from extraction through shipping to storage. Japan committed to launching a bilateral dialogue to strengthen India’s petroleum stockpiling system, and \u2014 in a move with longer-term institutional significance \u2014 pledged to back India’s membership of the International Energy Agency<\/strong>.<\/p>\n<\/p>\n IEA membership would integrate India more deeply into the global energy security architecture, providing both data access and a formal seat at the table during supply disruptions. Japan’s sponsorship carries weight within that institution.<\/p>\n<\/p>\n The Joint Statement on Cooperation in AI<\/strong> elevates the existing India-Japan AI Initiative into a strategic research and development partnership. The statement functions as a roadmap across the full AI technology stack, anchored in a shared vision of AI that is “safe, secure, trusted, inclusive and human-centric” \u2014 language that positions both countries within the governance-conscious camp of AI development rather than the permissive frontier.<\/p>\n<\/p>\n A memorandum of cooperation links the IndiaAI Mission<\/strong> with Japan’s GENIAC initiative<\/strong> through business-to-business matchmaking and joint projects. A separate memorandum of understanding addresses collaboration on large language models (LLMs)<\/strong>, with a specific focus on developing LLMs for enhanced scientific reasoning \u2014 a niche that reflects both countries’ interest in applied AI rather than consumer-facing generalist models.<\/p>\n<\/p>\n Two-way trade reached $27.5 billion in 2025\u201326<\/strong>, while Japanese foreign direct investment into India totalled $3.2 billion between April and December 2025<\/strong>. More than 100 new business agreements were concluded over the past year, paving the way for $10 billion in Japanese investments. Modi set a more ambitious longer-term target: attracting 10 trillion yen in Japanese investments over the next decade<\/strong> and doubling the number of Japanese companies operating in India.<\/p>\n<\/p>\n Japan’s infrastructure footprint in India is already substantial \u2014 metro networks across major cities, and the flagship Mumbai-Ahmedabad High-Speed Rail corridor<\/strong>, which Takaichi reaffirmed Japan’s commitment to supporting, acknowledging India’s target to commence commercial operations on priority sections in 2027. Both sides also acknowledged the goal of introducing Japan’s E10 bullet train, with Modi extending an invitation to Japanese firms to explore future high-speed corridor opportunities.<\/p>\n<\/p>\n The bilateral trade framework, however, is showing its age. The Comprehensive Economic Partnership Agreement (CEPA)<\/strong>, signed in 2011, was described by Foreign Secretary Vikram Misri as having become “somewhat dated” given the new trade arrangements being struck globally. India proposed a significant upgrade; Takaichi agreed that officials from both sides should meet to determine next steps. The upgrade, if it proceeds, would be the first substantive renegotiation of the agreement in over fifteen years.<\/p>\n<\/p>\n The summit produced a substantial layer of memorandums of cooperation and understanding that will shape implementation. These include frameworks for establishing 1,000 biogas and organic fertiliser plants across India through dairy cooperative networks; battery supply chain development; upstream critical minerals exploration; and a Next Generation Mobility Partnership<\/strong> covering rail, automotive, aviation, shipbuilding, ports, logistics, and urban development.<\/p>\n<\/p>\n Additional memorandums of understanding address deep tech and life sciences research, biological and neurological research, and cooperation in National Internet Registry operations and internet security. The breadth of these instruments is notable: it suggests both sides are moving to institutionalise cooperation at the technical and sectoral level, reducing dependence on political momentum to sustain the relationship.<\/p>\n<\/p>\n That institutional depth \u2014 rather than the bilateral warmth on display at the joint media interaction \u2014 is ultimately what will determine whether the 16th India-Japan Summit translates into durable strategic alignment or remains an impressive but episodic set of announcements.<\/p>","protected":false},"excerpt":{"rendered":" A Summit With Weight New Delhi and Tokyo have moved well beyond diplomatic pleasantries.
