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 Power System by the tip of June. Other than the home build-out of nuclear vitality, each plans reveal China’s ambition to turn out to be a world chief in nuclear vitality governance and reactor exports.
Virtually concurrently, the USA, 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. For the reason that Trump administration took workplace, the USA 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. In recent times, 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 Power Safety and Nuclear Power Challenges
Power safety is a serious vulnerability for Southeast Asia, as highlighted by the closure of the Strait of Hormuz, by means of which 60 p.c 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 probably 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 autos (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 robust 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 considered as having excessive upfront prices and lengthy building schedules. In the USA 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 price range.
For brand spanking new nuclear vitality international locations, working nuclear energy vegetation means not solely constructing reactors but in addition creating all the infrastructure, together with the regulatory framework, human sources, security tradition, and extra. The method, in response to the Worldwide Atomic Power 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, instructional, and authorized alignment.
Russia, China, and the USA are the main 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 enticing 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 method, with China Nationwide Nuclear Company (CNNC) and China Normal Nuclear Energy Group (CGN) as the principle 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 corporations don’t personal or function the reactors in Pakistan, however the gas provide depends on China.
The non-public sector has pushed U.S. nuclear vitality exports, however the authorities helps potential importing international locations by means of a number of packages. Foundational Infrastructure for Accountable Use of Small Modular Reactor Expertise (FIRST) builds capability for international locations with a robust concentrate on nuclear safety, security, and nonproliferation. Each the SMR Financing Toolkit by Export-Import Financial institution of the USA (EXIM) and loans, guaranties, and investments by the Worldwide Growth 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 contemplate a number of components concurrently. On the one hand, they worth U.S. management in expertise, 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 the USA, whereas Malaysia has secured a Memorandum of Understanding (MoU) to start negotiations. Then again, China’s value benefit and skill to complete on time are enticing, 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 by means of its state-owned nuclear vitality corporations 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 industrial operation timeline for China’s first Linglong One has not been met. As a result of opacity of data, 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. Varied authorities businesses have additionally stepped in to speed up regulatory alignment to favor the adoption of U.S. expertise within the area. The U.S. Commerce and Growth 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, the USA nonetheless has to beat the development bottleneck to enchantment 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 massive reactors within the UAE on schedule. The success has received 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 p.c of the massive solid elements 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 Power Geopolitics
Whereas the transfer to combine the capacities of the USA, South Korea, and Japan to create synergies and speed up SMR exports has acquired optimistic suggestions from the area, China can be persevering with its efforts. For the reason that launch of the 15 FYP, CNNC has signed new cooperation agreements with China Power Engineering Company (CEEC), TBEA, and Financial institution of China, citing worldwide market enlargement in all of them. CEEC is certainly one of 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 methods first after which work on the nuclear growth agenda; these partnerships will strengthen its capabilities to take action.
Southeast Asia has traditionally cooperated with China on financial agendas and collaborated with the USA 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 speedy vitality demand development domestically, the area should discover a strategy to preserve this balanced place whereas serving its personal wants.
