IPRD-2026 wraps up
The final day of the Indo-Pacific Regional Dialogue, organised with the National Maritime Foundation, covered ocean governance and maritime resilience, with speakers from the University of the Philippines, a former chief of staff of the International Seabed Authority, the Coalition for Disaster Resilient Infrastructure and a Swedish maritime organisation. A closing session looked at artificial intelligence, quantum technologies and other dual-use maritime technologies, and how small and medium navies can adopt them responsibly. Our report on the opening day is here.
Background
Malabar began as a bilateral India–US naval exercise in 1992. Japan later became a regular participant, and Australia rejoined in 2020, making it an exercise of all four Quad navies. INS Sahyadri came to Japan from South Korea, where it concluded a bilateral exercise with the Republic of Korea Navy at Busan earlier this week (our report).
What it means
Holding the exercise’s harbour phase in Japan, alongside India’s own dialogue on Indo-Pacific cooperation, shows how closely India is now working with Quad partners at sea, at a time of conflict in the Middle East and close attention to shipping routes. The exercise improves the ability of the four navies to operate together, which matters for securing sea lanes that carry much of Asia’s trade and energy.
