Vendor choice locks in dependencies for forty years or more
Across Southeast Asia, a quiet but consequential reckoning is underway: nations hungry for clean, reliable power are turning toward nuclear energy, and China — armed with proven reactor designs, state financing, and vertically integrated supply chains — is positioning itself as the partner of choice. From Vietnam's coastal plains to Thailand's industrial corridors, the decisions being made today will bind energy systems, regulatory frameworks, and geopolitical alignments for forty years or more. The choice of a nuclear vendor is, in the deepest sense, a choice about whose technological civilization one inhabits — and Southeast Asia is only beginning to reckon with that weight.
- Energy insecurity, climate targets, and surging demand from AI infrastructure are pushing Vietnam, the Philippines, Indonesia, Malaysia, Thailand, and Singapore toward nuclear power with unusual urgency.
- China is competing aggressively for these contracts, offering the Hualong One reactor — 41 units operational or under construction globally — bundled with financing, construction, training, and fuel supply in a single integrated package.
- Beijing has set a formal target of 30 reactor exports to Belt and Road nations by 2030, worth an estimated US$145 billion, and has already signed nuclear cooperation agreements across four continents.
- The commercial appeal is real, but so is the trap: choosing a vendor locks in fuel supply, maintenance, regulatory standards, and technical dependencies for the entire operational lifetime of a reactor — potentially four decades.
- Southeast Asian governments are now navigating the central tension: how to capture China's proven advantages in cost and speed while preserving enough strategic flexibility to avoid permanent technological dependence.
Southeast Asia is entering a new phase of energy infrastructure that will shape the region's strategic landscape for the next four decades. Vietnam formalized a nuclear plant agreement with Russia in early 2026, while the Philippines and Indonesia are targeting operational reactors by the early 2030s. Malaysia, Thailand, and Singapore are evaluating small modular reactors. The pressures are urgent: energy insecurity, climate commitments, and soaring electricity demand driven by industrial growth, data centres, and artificial intelligence.
Into this opening steps China with formidable credentials. By 2026, it operates 61 reactors with 36 more under construction — the world's fastest-growing fleet. Its flagship export, the Hualong One, is a third-generation pressurised water reactor with 41 units operational or under construction globally, generating up to 1,100 megawatts each. Roughly 90 per cent of its components are produced domestically, giving China the ability to offer complete packages — engineering, financing, construction, training, and fuel — all under Chinese control. Beijing has set an explicit target of 30 reactor exports to Belt and Road countries by 2030, worth an estimated US$145 billion. China is also advancing thorium molten salt reactor technology, which promises reduced waste and lower proliferation risk, adding a forward-looking dimension to its export portfolio.
Thailand illustrates how this partnership takes root. A Thai energy company acquired a stake in two Hualong One reactors in China's Guangxi province in 2015, with Chinese firms training Thai nuclear professionals on-site. A bilateral memorandum of understanding followed in 2025 — a template, China hopes, for deeper regional embedding.
Yet the strategic stakes are sobering. Selecting a nuclear vendor is a forty-year commitment that locks in fuel supply, maintenance, regulatory standards, and institutional knowledge. Only a handful of nations can enrich uranium at scale, and Russia currently dominates that market, though China is expanding rapidly. A country that chooses China today may find itself dependent on Chinese expertise, fuel, and spare parts for generations. China itself spent decades absorbing foreign technology before achieving true independence — a path that required sustained political will and investment. The real question for Southeast Asia is whether it can structure its nuclear partnerships to capture immediate benefits while building indigenous capability and preserving the strategic flexibility to chart its own course.
Southeast Asia is quietly entering a new era of energy infrastructure, one that will shape the region's technological and strategic landscape for the next four decades. Vietnam and Russia formalized an agreement in March 2026 to build the Ninh Thuan 1 nuclear power plant. The Philippines and Indonesia are targeting operational reactors by the early 2030s. Malaysia, Thailand, and Singapore are evaluating small modular reactors. The drivers are familiar but urgent: energy insecurity, climate commitments, and the relentless demand for electricity from industrial expansion, data centres, and artificial intelligence systems. Into this opening steps China, competing alongside France, Russia, South Korea, and the United States for contracts that will define the region's energy future.
China's position rests on six decades of accumulated nuclear capacity. As of 2026, the country operates 61 reactors and has 36 more under construction—the world's third-largest fleet and the fastest-growing. More importantly, China has achieved something that matters enormously in the export market: technological independence. It designs, manufactures, and builds reactors using primarily its own intellectual property, without relying on foreign licensing or components. The centrepiece of this export strategy is the Hualong One, a third-generation pressurised water reactor developed jointly by China National Nuclear Corporation and China General Nuclear Power Group. Forty-one units are now operational or under construction globally. Each generates between 1,090 and 1,100 megawatts—enough to power roughly one million homes. The design is deeply localised: approximately 90 per cent of components are produced domestically. This vertical integration allows China to offer complete packages—engineering, procurement, construction, financing, training, fuel supply—all bundled together, all controlled by Chinese firms.
Beijing has set an explicit target: export 30 reactors to Belt and Road Initiative countries by 2030, generating an estimated 1 trillion yuan, or about US$145 billion, in revenue. Nuclear cooperation agreements are already signed with Pakistan, Argentina, Kenya, Kazakhstan, and Saudi Arabia. The strategy works because China can absorb the capital costs that deter other exporters, and because its integrated supply chains allow tighter cost control and faster construction timelines. China is also moving beyond conventional uranium reactors. In June 2024, the Wuwei Thorium Molten Salt Reactor reached full power capacity. Thorium-based systems use liquid fuel dissolved in molten salt coolants, allowing refuelling without shutting down the reactor. For developing countries, thorium offers long-term appeal: wider resource availability, enhanced safety, dramatically reduced high-level radioactive waste, and lower proliferation risk compared to uranium. It is a technology still maturing commercially, but one that could reshape how emerging economies approach energy security.
Thailand offers a concrete example of how this partnership functions. In 2015, Ratchaburi Electricity Generating Holding, Thailand's largest private power company, acquired a 10 per cent stake in two Hualong One reactors at the Fangchenggang nuclear power plant in Guangxi province. China General Nuclear Power Group has been training Thai nuclear professionals at the site, effectively using the project as a demonstration and training ground for future exports. This cooperation culminated in a 2025 Memorandum of Understanding between China and Thailand on peaceful nuclear energy use. The relationship is not merely transactional; it is a template for how China intends to embed itself in Southeast Asia's nuclear infrastructure.
Yet beneath the commercial appeal lies a deeper strategic reality that Southeast Asian policymakers are beginning to grapple with. Selecting a nuclear vendor is not simply a purchasing decision. It is a commitment that extends across four decades or more—the operational lifetime of a reactor. That choice locks in dependencies: fuel supply, maintenance protocols, technical support, regulatory standards, institutional capacity. Only a handful of countries can enrich uranium at scale—primarily the major nuclear powers plus Brazil, Germany, Japan, and the Netherlands. Russia dominates the global market for low-enriched uranium, though China is rapidly expanding its own fuel cycle capabilities. Maintenance and upgrades remain tied to the original vendor, embedding long-term reliance in both technical systems and governance. A country that chooses China today may find itself dependent on Chinese expertise, Chinese fuel, Chinese regulatory frameworks, and Chinese spare parts for the next forty years.
China itself navigated this problem by drawing on technologies from Canada, France, Russia, and the United States before developing reactors with independent intellectual property rights—a process that required decades of sustained policy commitment and investment. The question for Southeast Asia is whether it can replicate that path while avoiding the pitfalls. The region's challenge is to adopt, adapt, standardise, and ultimately indigenise imported technologies while simultaneously building a workforce of qualified engineers, scientists, skilled technicians, and regulators. China offers proven advantages: mature technology, rapid deployment, and robust capacity-building support. But those advantages come with the risk of long-term technological and fuel-supply lock-in. The real test will be whether Southeast Asian countries can structure their engagement with China—and with other partners—in ways that maximise immediate benefits while preserving strategic flexibility and nurturing indigenous capability. The vendor choice made today will echo through the region's energy systems, geopolitical alignments, and technological trajectories for generations.

The Hearth Conversation Another angle on the story
Why does it matter so much which country builds a nuclear reactor for you? Isn't a reactor just a reactor?
Because a reactor is not just a machine—it's a relationship. Once it's built, you're dependent on that country for fuel, spare parts, maintenance, training, expertise. That dependency lasts forty years or more. You're not just buying technology; you're buying into a long-term strategic partnership.
So if China builds a reactor in Thailand, Thailand becomes dependent on China?
Not overnight. But gradually, yes. Thai engineers learn from Chinese engineers. Thai regulators adopt Chinese standards. Thai supply chains become integrated with Chinese suppliers. After twenty years, it becomes very difficult to switch partners without massive disruption.
But China is offering better terms than the Americans or Europeans, right?
Much better. China can finance the whole project, absorb the capital costs, deliver faster, and offer integrated packages. That's genuinely attractive when you need electricity now and your budget is limited. The question is whether the long-term cost of dependency outweighs the short-term savings.
Is there a way to avoid the lock-in?
China itself did it. It borrowed technology from multiple countries—Canada, France, Russia, the US—and over decades developed its own independent capability. Southeast Asia could try the same thing: work with China but also with other partners, invest heavily in building local expertise, and deliberately avoid putting all your eggs in one basket.
That sounds expensive and complicated.
It is. But the alternative is waking up in 2050 and realising you can't make a major decision about your own energy system without Beijing's permission. For a region trying to build independence, that's a high price to pay.
