India's Energy Diplomacy in Southeast Asia: Strategic Lessons for Vietnam

In an era of intensifying geopolitical competition, energy diplomacy has emerged as a critical frontier in Southeast Asia, where rapidly growing energy consumption intersects with strategic competition among major powers. As nations vie for influence in this resource-rich region, India has positioned itself as a significant player, pursuing a multifaceted energy strategy that balances its economic needs with geopolitical objectives.



Against this backdrop, Vietnam faces critical questions about its own energy future. As energy demands continue to rise across Southeast Asia, Vietnam must navigate complex energy markets while securing its strategic interests. The question looms: can Vietnam afford to lag in developing its energy diplomacy capabilities, potentially falling behind in the race for strategic energy supplies in Asia?



India's Energy Imperative and Strategic Shift

India stands as one of the world's largest energy consumers, facing significant challenges in meeting its growing demands. The country imports approximately 80% of its crude oil and 25% of its natural gas, creating substantial vulnerabilities in an increasingly volatile global energy landscape. This dependence becomes particularly acute amid global uncertainties stemming from the Russia-Ukraine conflict, Middle East tensions, and disruptions in supply chains.



Recognizing these vulnerabilities, India has strategically pivoted toward Southeast Asia, a region endowed with abundant energy resources. The area holds approximately 22 billion barrels of oil reserves, 227 trillion cubic feet of natural gas, 46 billion tons of coal, and significant potential in hydropower (234 GW) and geothermal energy (20 GW). These resources make Southeast Asia an attractive partner for India's energy security strategy.



India's Energy Import Dependence
Crude oil import dependencyApproximately 80%
Natural gas import dependencyApproximately 25%
Total energy import billOver $100 billion annually

India's energy diplomacy represents more than mere commercial transactions; it forms an integral part of its "Act East" policy aimed at strengthening relations with ASEAN nations, expanding regional influence, and creating a strategic balance against China. While Beijing advances its Belt and Road Initiative, India has been constructing its own network of energy cooperation across Southeast Asia, with particular focus on Vietnam, Myanmar, Indonesia, Malaysia, Thailand, the Philippines, and Singapore.



Strategic Energy Partnerships in the Region

Vietnam: A Cornerstone of India's Energy Strategy

Vietnam occupies a central position in India's energy diplomacy in Southeast Asia. The two nations have cultivated energy cooperation for years, most notably through ONGC Videsh's participation in Block 06.1 in Vietnam's continental shelf. This block has made substantial contributions to Vietnam's domestic gas demand, demonstrating that energy cooperation between the two countries carries both economic significance and direct implications for national energy security.



Strategic trust between Vietnam and India is further evidenced by Vietnam's invitation for India to participate in exploration of additional oil and gas blocks in the South China Sea. This collaboration not only addresses energy needs but also reinforces maritime security cooperation in a contested region where energy resources, sovereignty claims, and maritime security are inextricably linked.



Myanmar: Ambitious Projects Facing Political Uncertainty

Myanmar once represented a significant component of India's energy strategy, featuring ambitious plans including the $6 billion Thanlyin oil refinery project and additional investments of over $121 million by ONGC Videsh in offshore oil and gas projects. These initiatives aimed to expand India's energy access through Myanmar's strategic location between South and Southeast Asia.



However, political developments since 2021 have disrupted many of these plans, highlighting the geopolitical risks that can impede or nullify energy projects despite significant economic potential. This case underscores the complex interplay between energy diplomacy and political stability that nations must navigate.

India's Evolution: From Energy Seeker to Green Technology Provider

India's approach to energy diplomacy has evolved significantly, transitioning from a position primarily seeking energy supplies to becoming an investor, technology provider, and green infrastructure connector. Indian conglomerates like Adani and Greenko are actively pursuing opportunities across Southeast Asian markets, signaling a strategic shift in India's regional energy engagement.



In Vietnam, Adani has invested in wind and solar power projects in Ninh Thuan province, with plans for additional renewable energy projects exceeding 350 MW. Similarly, Greenko, in partnership with Keppel Infrastructure, is targeting green hydrogen exports to Singapore starting in 2025, positioning India at the forefront of the emerging green hydrogen economy.



India is also exploring regional electricity grid connectivity through Myanmar and Thailand, potentially creating an ASEAN-wide electricity exchange corridor. Such infrastructure development could transform regional energy markets, enabling cross-border electricity trade and enhancing energy security across the region.



Implications for Southeast Asia's Energy Landscape

The expansion of India's energy diplomacy offers both opportunities and challenges for Southeast Asian nations. On one hand, India's presence provides additional alternatives beyond traditional partners like China, Japan, South Korea, Europe, and the United States. This diversification enhances ASEAN countries' negotiation leverage, providing access to new technologies, investment capital, and energy management expertise.



On the other hand, the intensifying competition among major powers introduces geopolitical complexities. This competition is particularly evident in the South China Sea, where energy resources, territorial sovereignty, and maritime security remain deeply intertwined. As nations pursue their energy interests, the risk of regional tensions escalates, potentially complicating energy development projects in contested waters.



India's entry into Southeast Asia's energy landscape creates a more balanced dynamic. While China maintains advantages in capital, infrastructure development, and implementation speed, Japan and South Korea excel in technology, finance, and industrial standards. India has carved its own niche by emphasizing strategic oil and gas partnerships, renewable energy, solar power, green hydrogen, and grid interconnectivity.



Strategic Lessons for Vietnam

Energy Diplomacy as a Core Economic Pillar

The first critical lesson for Vietnam is to elevate energy diplomacy to a core component of economic diplomacy, rather than treating it merely as a technical matter or investment within the electricity and oil sectors. As energy demands accelerate, Vietnam must proactively expand partnerships, diversify supply sources, and attract technology and capital for key sectors including LNG, offshore wind, solar power, energy storage, smart grids, and hydrogen.



Leveraging Geographical Strategic Position

Secondly, Vietnam should leverage its strategic geographical location to become a vital link in the regional energy chain. With its extensive coastline, significant offshore wind potential, rapidly growing electricity demand, and proximity to critical maritime shipping lanes, Vietnam is well-positioned to develop not just as an energy consumer but as a regional hub for energy production, technical services, and connectivity within ASEAN.



Enhancing Technological Self-Reliance

The third lesson involves strengthening technological self-reliance. While international cooperation remains essential, over-reliance on foreign capital, equipment, and technology can create vulnerabilities. Vietnam should promote domestic research and development, build supporting industries for energy technology, and enhance the capabilities of state-owned enterprises like Petrovietnam, EVN, PV GAS, PTSC, BSR, and private sector companies within the new energy supply chain.



Comprehensive Risk Assessment

The fourth lesson emphasizes the need for comprehensive risk assessment in international energy projects. The Myanmar case demonstrates that multi-billion dollar projects can face significant delays or cancellation in politically unstable environments. For Vietnam's oil and gas, LNG, cross-border electricity, hydropower, offshore wind, or energy port projects, thorough evaluation of legal, security, sovereignty, financial, and policy change risks at host countries is essential.



Conclusion

India's energy diplomacy in Southeast Asia illustrates how energy has transcended its industrial role to become a strategic tool in shaping international relations. For Vietnam, substantial opportunities are emerging, accompanied by intensifying competitive pressures. The nation that develops a proactive, flexible, and substantive energy diplomacy strategy will gain significant advantages in ensuring energy security, attracting investment, and enhancing its position within the global energy value chain.



As Southeast Asia continues its energy transition while navigating complex geopolitical dynamics, Vietnam's approach to energy diplomacy will be crucial in determining its energy future and regional standing. By learning from both successes and challenges in India's energy diplomacy, Vietnam can craft a path that balances economic development, energy security, and strategic autonomy in an increasingly competitive global energy landscape.
