After launching its fifteenth 5-12 months Plan (FYP) in March, the Chinese language authorities has been publishing sectoral plans, together with the fifteenth 5-12 months Plan for Constructing a Stunning China and the fifteenth 5-12 months Plan for a New-type Vitality System by the top of June. Aside from the home build-out of nuclear vitality, each plans show China’s ambition to develop into a world chief in nuclear vitality governance and reactor exports.
Virtually concurrently, america, Japan, and South Korea introduced a brand new Memorandum of Cooperation on the NATO Summit to speed up the deployment of small modular reactors (SMRs) in third international locations, starting with the Indo-Pacific.
These parallel developments sign that nuclear reactor exports have gotten an more and more essential enviornment of strategic competitors. Because the Trump administration took workplace, america has linked the deployment of nuclear reactors, each domestically and internationally, to nationwide safety. The “123 Settlement” for peaceable cooperation has been the important thing indicator of U.S. nuclear vitality diplomacy. Lately, new signatories to the 123 Agreements and international locations expressing curiosity in them have concentrated in Southeast Asia – the identical area the place China is focusing its civil nuclear engagement.
Southeast Asia’s Vitality Safety and Nuclear Vitality Challenges
Vitality safety is a serious vulnerability for Southeast Asia, as highlighted by the closure of the Strait of Hormuz, via which 60 % of Southeast Asia’s crude oil passes. To deal with the disruptions, some Southeast Asian governments rolled out short-term measures to curb vitality demand. Nevertheless, any such efforts will likely be short-lived.
Southeast Asia’s electrical energy demand is projected to develop by greater than 100 TWh by 2030, pushed by information facilities, electrical automobiles (EVs), and industrial wants. That can necessitate enhanced vitality provide and safety. With that in thoughts, some international locations, together with Indonesia, the Philippines and Vietnam have demonstrated a powerful curiosity in nuclear vitality by setting nationwide targets to function their first nuclear reactors earlier than 2035. Another international locations, together with Malaysia, Myanmar, Singapore, and Thailand, are actively contemplating nuclear vitality as a part of their vitality combine. These pursuits focus particularly on SMRs.
Nuclear reactors are sometimes seen as having excessive upfront prices and lengthy building schedules. In america and Europe, new-built reactors have been uncommon in recent times, and the licensing course of and lack of building experience have extended challenge timelines and additional elevated prices. In distinction, most newly constructed reactors are constructed by Asian international locations, primarily China and South Korea, which have confirmed their capability to construct reactors on time and on funds.
For brand new nuclear vitality international locations, working nuclear energy vegetation means not solely constructing reactors but additionally growing all the infrastructure, together with the regulatory framework, human assets, security tradition, and extra. The method, in response to the Worldwide Atomic Vitality Company (IAEA), takes round 10 to fifteen years. Because the lifetime of a reactor has been prolonged to 60 to 80 years, and decommissioning takes one other 10 to 25 years, importing a reactor from one other nation means 100 years of political, logistical, academic, and authorized alignment.
Russia, China, and america are the key nuclear reactor exporters worldwide. Russia leads within the variety of reactors exported with state-owned Rosatom. Its capability to cowl all the gas cycle and its build-own-operate mannequin are engaging to new nuclear vitality international locations. Nonetheless, sanctions following the Russian invasion of Ukraine have considerably affected its financing and logistical capabilities, leading to building delays.
China additionally adopts a state-owned firm strategy, with China Nationwide Nuclear Company (CNNC) and China Normal Nuclear Energy Group (CGN) as the primary gamers. Though China was as soon as set to construct 30 reactors in Belt and Highway Initiative (BRI) international locations by 2030, it has to date constructed reactors solely in Pakistan. Chinese language firms don’t personal or function the reactors in Pakistan, however the gas provide relies on China.
The non-public sector has pushed U.S. nuclear vitality exports, however the authorities helps potential importing international locations via a number of applications. Foundational Infrastructure for Accountable Use of Small Modular Reactor Expertise (FIRST) builds capability for international locations with a powerful concentrate on nuclear safety, security, and nonproliferation. Each the SMR Financing Toolkit by Export-Import Financial institution of america (EXIM) and loans, guaranties, and investments by the Worldwide Improvement Finance Company (DFC) are supposed to assist the excessive upfront funding of nuclear reactors that may trigger a monetary burden for international locations. The USA doesn’t take again spent gas for export, however increasingly coverage discussions favor gas recycling to spice up its gas capability.
In Southeast Asia, when deciding which nation to import nuclear reactors from, international locations think about a number of components concurrently. On the one hand, they worth U.S. management in know-how, regulatory framework, nonproliferation, and security tradition. Amongst Southeast Asian international locations exploring nuclear vitality, Indonesia, the Philippines, Vietnam, Singapore, and Thailand have all signed 123 Agreements with america, whereas Malaysia has secured a Memorandum of Understanding (MoU) to start negotiations. However, China’s value benefit and skill to complete on time are engaging, given these international locations’ nationwide targets on the horizon.
The Engagement China and the U.S.-led Alliance Have Made within the Area
China started civil nuclear cooperation with the Affiliation of Southeast Asian Nations (ASEAN) in 2015 via its state-owned nuclear vitality firms to construct capability within the nuclear vitality workforce. After China’s Linglong One turned the world’s first IAEA-approved land-based SMR mannequin, it has demonstrated its capability to serve the wants of BRI international locations, which embody all ASEAN international locations.
Nevertheless, regardless of main the world in SMR progress, the business operation timeline for China’s first Linglong One has not been met. Because of the opacity of knowledge, whether or not the primary Linglong One can function efficiently stays a key query for international locations contemplating nuclear vitality choices.
The USA has made some regulatory breakthroughs in Southeast Asia. In 2025, U.S. nuclear firm Thorcon Worldwide acquired a primary stage license from the Indonesian nuclear regulator, BAPETEN, for its molten salt reactor. Numerous authorities businesses have additionally stepped in to speed up regulatory alignment to favor the adoption of U.S. know-how within the area. The U.S. Commerce and Improvement Company (USTDA) funded the Manila Electrical Firm (Meralco) within the Philippines to conduct a research on integrating U.S. SMRs. The U.S. Division of Commerce arrange an SMRs export working group to help the business’s communications with Southeast Asian governments. These steps sign U.S. efforts to unify the non-public sector to type an export technique.
Regardless of the regulatory integration, america nonetheless has to beat the development bottleneck to attraction to Southeast Asian international locations, and that’s the place South Korea and Japan play key roles.
South Korea is an rising nuclear reactor building energy with its state-owned Korea Hydro & Nuclear Energy (KHNP), which has efficiently constructed 4 giant reactors within the UAE on schedule. The success has gained them additional offers with Egypt and Czechia, and KHNP has signed SMR cooperation MOUs with Singapore, the Philippines (Meralco), and Thailand.
Japan is a key provider to the nuclear vitality business, with main capabilities in heavy manufacturing: Japan Metal Works (JSW) provides the world with 80 % of the massive solid parts for nuclear reactors. Within the 2025 commerce deal between the U.S. and Japan, leveraging Japan’s capabilities to rebuild the U.S. nuclear vitality business was a key focus.
The Subsequent Chapter of Nuclear Vitality Geopolitics
Whereas the transfer to combine the capacities of america, South Korea, and Japan to create synergies and speed up SMR exports has acquired optimistic suggestions from the area, China can also be persevering with its efforts. Because the launch of the 15 FYP, CNNC has signed new cooperation agreements with China Vitality Engineering Company (CEEC), TBEA, and Financial institution of China, citing worldwide market enlargement in all of them. CEEC is one in all China’s largest abroad vitality challenge builders, working in 140 international locations and areas, whereas TBEA focuses on offering whole options for renewable vitality and transmission. CNNC has demonstrated the intention to combine itself in different international locations’ vitality programs first after which work on the nuclear improvement agenda; these partnerships will strengthen its capabilities to take action.
Southeast Asia has traditionally cooperated with China on financial agendas and collaborated with america on safety. The area has been navigating nuclear vitality cooperation with each side. Amid the heightened geopolitical competitors in nuclear vitality exports, a world vitality disaster, and fast vitality demand progress domestically, the area should discover a method to keep this balanced place whereas serving its personal wants.
