This paper explores the potential for maritime strategic cooperation between India and Vietnam in the context of evolving regional security dynamics in the Indo-Pacific region. The study employs a qualitative secondary research methodology, including a review of relevant literature, policy analysis, and expert opinions. The research identifies the strategic interests, challenges, and opportunities for cooperation between the two countries in the maritime domain. The study tests three hypotheses related to the potential benefits of cooperation in terms of regional security, economic development, and diplomatic influence. The research finds that India and Vietnam share converging strategic interests in the maritime domain, including the need to counterbalance China's assertiveness, secure sea lanes of communication, and develop their maritime economies.
