India and Japan on Thursday elevated their Special Strategic and Global Partnership with a broad set of agreements spanning artificial intelligence (AI), defence, economic security, clean energy and next-generation mobility, signalling a deeper strategic convergence amid growing geopolitical and supply chain challenges.
The announcements came after the 16th India-Japan Annual Summit in New Delhi, where Prime Minister Narendra Modi and Japanese Prime Minister Sanae Takaichi held bilateral talks focused on strengthening cooperation across emerging technologies, resilient supply chains and regional security.
Addressing a joint press statement, Modi said mutual trust remained the foundation of bilateral ties and described technology as one of the defining pillars of the partnership. He said Japan's expertise in precision manufacturing, combined with India's software capabilities, would accelerate the development of globally competitive AI technologies.
The two countries issued a Joint Statement on AI, while leading Indian AI institutions signed agreements with Japanese counterparts to deepen research and innovation partnerships.
According to Vanshika Saraf, Research Analyst at The Takshashila Institution, the relationship has steadily evolved beyond traditional economic cooperation into areas that will shape future geopolitical influence.
"The trajectory has been tremendously positive. Both sides have converged on emerging concerns such as supply chain resilience, defence indigenisation and economic security. The adoption of major agreements on AI and energy security indicates that the partnership is increasingly focused on technologies and industrial capabilities that will define future geopolitical power," she said.
Saraf added that stronger Japanese investment commitments also reflected confidence in India's long-term economic prospects.
Defence, Economic Security Take Centre Stage
A key outcome of the summit was the signing of the first India-Japan defence co-development agreement for a naval radio antenna, marking a significant milestone in bilateral defence technology cooperation.
Modi said the project would serve as the foundation for future joint development of advanced defence technologies, contributing to maritime security, regional peace and a rules-based Indo-Pacific.
The two sides also adopted a Joint Roadmap on Economic Security aimed at strengthening resilient supply chains across strategic sectors, including semiconductors, quantum technologies and advanced materials.
Saraf said the initiatives reflected a shared recognition that economic security has become inseparable from national security.
She said that while questions have emerged over the future direction of the Quad following reduced leader-level engagement by the United States under President Donald Trump, it would be premature to conclude that the grouping had lost strategic relevance.
"Concerns over maritime coercion, critical-mineral concentration and China's regional influence remain. For both India and Japan, the Quad continues to be useful for securing sea lanes and building trusted technology networks," she said, adding that both countries could jointly mobilise greater financial and logistical resources to strengthen regional capabilities.
Clean Energy, Mobility Drive Future Cooperation
The summit also produced an ambitious clean energy agenda. India and Japan launched the India-Japan Biogas Initiative, under which 1,000 biogas and organic fertiliser plants will be established across India.
The two countries further agreed to deepen cooperation in battery technologies, green hydrogen, nuclear energy and broader energy resilience to support the clean energy transition while enhancing energy security.
In another major initiative, the leaders unveiled the India-Japan Next Generation Mobility Partnership Framework, expanding bilateral collaboration beyond automobiles into shipbuilding, aviation and logistics.
Saraf said the growing partnership would also help both countries reduce strategic vulnerabilities arising from concentrated global supply chains.
"Both remain exposed to concentrated sources of semiconductors, rare earths and energy flows. Japan brings strengths in specialised materials, precision equipment and advanced manufacturing, while India offers market scale, software capabilities and the potential to host additional manufacturing capacity. Together, these complementarities strengthen their ability to diversify supply chains and respond to future geopolitical and economic shocks," she said.
The expanding scope of India-Japan relations, with both countries seeking to build long-term resilience through cooperation in critical technologies, advanced manufacturing, defence production and clean energy as they navigate an increasingly uncertain strategic environment. |
