The strategic partnership between India and the United States has increasingly focussed on joint Humanitarian Assistance and Disaster Relief (HADR) efforts in the Indian Ocean Region. Cemented by India’s 2016 designation as a ‘Major Defence Partner’, this collaboration now includes joint military exercises, port visits and disaster relief missions. Given the Indo- Pacific region’s importance due to its population and key shipping routes, improved military interoperability and logistical coordination are crucial for tackling climate-related disasters. India’s strong HADR capabilities and capacity-building, along with the strategic support of the United States, have enhanced their bilateral and multilateral cooperation, vital for addressing regional challenges and maintaining stability in the Indo-Pacific.
