India and Thailand Deepen Defence Cooperation as Indo-Pacific Security Gains Strategic Weight

India and Thailand have agreed to strengthen defence cooperation in manufacturing, research, innovation and capability development during the 10th Thailand–India Defence Dialogue held in Bangkok on 16 June 2026. The dialogue reviewed the full range of bilateral defence cooperation and assessed regional and global security issues of mutual interest. It was co-chaired by Thailand’s Deputy Permanent Secretary for Defence Admiral Nuttapol Diewvanich and India’s Joint Secretary in the Ministry of Defence, Satyajit Mohanty.

The meeting comes at a time when the Indo-Pacific has become one of the world’s most important strategic regions. India and Thailand sit across crucial maritime routes connecting the Indian Ocean, the Bay of Bengal, the Andaman Sea and the wider Pacific theatre. Their defence engagement therefore carries importance beyond bilateral ties. It directly supports regional stability, maritime awareness, secure sea lanes and practical cooperation among friendly countries.

Both sides discussed the evolving security environment in the Indo-Pacific and exchanged views on regional developments. They reaffirmed their shared commitment to peace, stability and prosperity in the region. This language reflects the growing convergence between New Delhi and Bangkok on maritime security, rules-based cooperation and regional resilience.

A key part of the dialogue focused on military-to-military engagement. India and Thailand reviewed ongoing defence exchanges, training programmes, capacity-building initiatives and maritime cooperation. These areas form the operational base of the relationship. Regular interaction between armed forces improves coordination, builds trust and creates familiarity between defence institutions.

Maritime cooperation is especially important. Thailand’s geography gives it a vital position near the Andaman Sea and the Malacca Strait, while India’s Andaman and Nicobar Command gives New Delhi a forward strategic presence in the eastern Indian Ocean. Stronger defence coordination between the two countries can support search and rescue, humanitarian assistance, anti-piracy efforts, disaster relief, maritime domain awareness and naval cooperation.

The dialogue also placed strong emphasis on defence industry cooperation. The two sides discussed ways to deepen collaboration in defence manufacturing, research, innovation and capability development. This is significant because India is now actively expanding its defence industrial partnerships with friendly countries, especially in areas where co-development, joint production, electronics, naval systems, drones, surveillance platforms and maintenance ecosystems can create long-term value.

For India, the defence manufacturing conversation fits into the larger Atmanirbhar Bharat defence push. Indian public and private defence companies are increasingly looking at Southeast Asia as a natural partner region for exports, joint ventures and technology collaboration. Thailand, with its own defence modernisation needs and strategic location, can become an important partner in this process.

For Thailand, deeper engagement with India offers access to a large defence market, growing military technology base and a trusted regional partner with strong naval, aerospace, missile, electronics and training capabilities. Defence cooperation with India also gives Bangkok another channel to diversify its security partnerships while remaining anchored in ASEAN-led regional frameworks.

The dialogue also covered cooperation under regional and multilateral defence platforms, including ASEAN-led mechanisms. This is important because Thailand is a key ASEAN member and India’s Act East policy places ASEAN at the centre of regional outreach. Defence cooperation through ASEAN-linked mechanisms allows both countries to address shared security challenges through structured dialogue, joint exercises and coordinated regional approaches.

The wider diplomatic background is also important. India and Thailand elevated their bilateral relationship to a formal Strategic Partnership in 2025. The 10th Defence Dialogue therefore builds on that upgraded political framework and gives it a stronger security dimension.

The outcome of the Bangkok meeting shows that India–Thailand defence relations are moving from routine engagement toward deeper practical cooperation. Training, maritime security and military exchanges remain the foundation. Defence industry, research and innovation are now becoming the next pillar. As the Indo-Pacific becomes more contested and complex, India and Thailand are positioning their defence partnership as a stabilising force in the eastern Indian Ocean and Southeast Asian region.
