India and Thailand elevated their bilateral relations to a Strategic Partnership in April 2025 during the official visit of the Indian Prime Minister to Thailand. This structural upgrade reflects a deep convergence across political, economic, connectivity, and national security domains, expanding on over seven decades of formal diplomatic engagement established in 1947. Positioned as Southeast Asia’s third-largest economy and a central member of the Association of Southeast Asian Nations (ASEAN), Thailand serves as India’s vital gateway to the broader Mekong sub-region. The enhanced partnership bridges India’s Act East Policy with Thailand’s Act West Policy, anchoring regional supply chains, maritime stability, and technical collaboration.
