Context:

• The state visit of Tô Lâm to India in May 2026 marked a significant step in strengthening India-Vietnam relations amid evolving Indo-Pacific geopolitics.
• During the visit, both countries upgraded ties to an Enhanced Comprehensive Strategic Partnership and signed agreements covering defence, technology, finance, and energy cooperation.
• The visit reflected growing strategic convergence between India and Vietnam, particularly over concerns regarding China’s assertiveness in the South China Sea, maritime security, supply chain resilience, and strategic autonomy.
• India’s Act East policy and the 2016 Comprehensive Strategic Partnership had already laid the foundation for closer defence cooperation, high-level exchanges, and institutionalised security engagement, which have steadily deepened mutual trust over the years.
• This article highlights the emergence of a new phase in India–Vietnam relations marked by deeper defence, economic, and strategic cooperation amid evolving Indo-Pacific geopolitical dynamics and regional security challenges.

Defence and Economic Cooperation in India–Vietnam Relations

• Defence cooperation has become the central pillar of ties between India and Vietnam.
• India has expanded support through:
  • transfer of the INS Kirpan in 2023,
  • defence financing assistance,
  • military training programmes, and
  • maritime cooperation initiatives.
• Discussions regarding the possible export of BrahMos missile systems to Vietnam indicate a shift from basic defence capacity-building towards enhancing Vietnam’s deterrence capabilities in the South China Sea.
• Economic ties are also gaining importance, with bilateral trade crossing $16 billion and both countries aiming to raise it to $25 billion by 2030.
• Focus on Supply Chain Resilience
  • The partnership increasingly emphasises:
    • resilient supply chains,
    • rare earth cooperation, and
    • digital payment integration.
• Vietnam’s Strategic Economic Importance
  • Vietnam’s role as a major ASEAN manufacturing hub makes it an important partner for India’s efforts to diversify supply chains and reduce excessive dependence on China-centred production networks.

Regional Impact of the India–Vietnam Partnership

• Role in Indo-Pacific Strategic Balancing - The growing partnership between India and Vietnam has become an important element of strategic balancing in the Indo-Pacific region.
• Support for a Rules-Based Maritime Order - Alongside countries such as Japan, Australia, and the United States, both nations support a rules-based maritime order focused on maintaining peace, stability, and the rule of law in the South China Sea.
• Strengthening ASEAN’s Centrality - The partnership highlights the importance of Association of Southeast Asian Nations (ASEAN) in India’s Indo-Pacific strategy. Vietnam’s strategic importance and assertive regional role make it a key partner for India’s engagement with Southeast Asia.
• Convergence of Foreign Policy Approaches - Vietnam’s policy of strategic diversification and hedging aligns closely with India’s multidimensional partnership strategy, creating a natural basis for deeper cooperation.
• Emerging Technologies and Economic Security - Cooperation in critical minerals, advanced technologies, and supply chain resilience reflects the changing nature of geopolitical competition in the Indo-Pacific.
• Towards Alternative Economic Architectures - As global supply chains become increasingly securitised, the India–Vietnam partnership is evolving beyond traditional trade relations towards a broader framework of economic security and strategic resilience.

Structural Challenges in India–Vietnam Relations

• Need to Convert Strategy into Action - Despite strong political and strategic alignment, India and Vietnam still face challenges in translating strategic intentions into concrete operational outcomes.
• Implementation Gaps - Key areas such as - trade expansion, connectivity projects, and defence industrial cooperation - continue to face implementation hurdles.
• Challenges in Defence Cooperation - Potential defence exports, including the BrahMos missile system, may encounter scientific, financial, and geopolitical constraints before becoming operational realities.
• Barriers to Trade Expansion - Achieving ambitious bilateral trade targets will require addressing: logistics bottlenecks, legal and regulatory issues, and greater participation from the private sector.
• Growing Importance in the Indo-Pacific - As geopolitical competition intensifies in the Indo-Pacific, the India–Vietnam partnership is expected to become more deeply integrated into the region’s emerging strategic architecture.
• A Mature Strategic Partnership - Tô Lâm’s visit symbolises not merely a diplomatic event but the evolution of India–Vietnam ties into a mature, multidimensional, and strategically significant partnership.

Conclusion

The India–Vietnam partnership is evolving into a multidimensional strategic relationship driven by shared Indo-Pacific interests, defence cooperation, economic resilience, and long-term regional stability goals.
