Argentina and the U.S. Are co-hosting a regional nuclear energy workshop in Buenos Aires this week, bringing together Latin American officials, energy ministers, and private sector stakeholders to discuss small modular reactor (SMR) technology and civilian nuclear cooperation. The event, supported by Canada’s Global Affairs, marks a rare alignment between Washington and Buenos Aires on nuclear policy—just as Argentina’s CNEA prepares to expand its fleet of reactors, including a controversial Chinese-backed project in Patagonia. Here’s why it matters: This workshop isn’t just about energy; it’s a geopolitical chess move where Argentina’s nuclear ambitions clash with U.S. Strategic interests in a region increasingly courted by Beijing, and Moscow.
The Nuclear Triangle: Argentina, the U.S., and the Race for Latin American Energy Dominance
Argentina’s nuclear sector has long been a battleground between ideological blocs. The country’s first reactor, Atucha I, was commissioned in 1974 under the military junta—backed by Westinghouse—while Atucha II, a Russian-designed plant, was completed in 2014 under Kirchnerism. Now, with the Chinese-backed CAREM reactor nearing completion in Lobería and plans for a second unit, Buenos Aires is doubling down on non-Western partnerships. The U.S., meanwhile, has been quietly pushing SMRs as a “clean energy” counter to Beijing’s Belt and Road Initiative (BRI) in the region.
Here’s the catch: Argentina’s nuclear strategy isn’t just about energy security. It’s a hedge against U.S. Sanctions and a test case for how Latin America can diversify away from Washington’s influence. The workshop’s timing—just months after the Biden administration’s Regional Security Strategy for the Americas—suggests a deliberate effort to co-opt Argentina’s nuclear narrative before China’s influence solidifies further.
How the Workshop Reshapes Global Supply Chains (And Who Wins)
The workshop’s focus on SMRs isn’t accidental. Small modular reactors are poised to disrupt the global nuclear energy market, which is currently dominated by traditional reactor designs from the U.S., France, Russia, and China. Argentina’s CNEA has already signed a memorandum of understanding with U.S.-based NuScale Power for SMR collaboration, but the real prize is Latin America’s burgeoning energy demand—projected to grow by 40% by 2035 according to the IEA.
For the U.S., this is a chance to insert itself into a region where China’s state-backed nuclear firms—like China National Nuclear Corporation (CNNC)—have already secured deals in Brazil, Chile, and Argentina. But there’s a catch: Argentina’s nuclear sector is mired in debt, with the CNEA owing $1.2 billion in unpaid bills to Russian and Chinese suppliers. The workshop’s SMR focus could be a Trojan horse for U.S. Firms to offer financing packages tied to Western technology standards, effectively locking Argentina into a new energy dependency—this time on Washington.
“Argentina’s nuclear strategy is a classic case of ‘friend-shoring.’ By hosting this workshop, Buenos Aires is signaling to the U.S. That it wants access to advanced technology, but it’s not abandoning its partnerships with Beijing. The real question is whether the U.S. Can offer a compelling alternative—or if Argentina will simply play the two sides against each other.”

The Geopolitical Ledger: Who Gains Leverage?
Argentina’s nuclear diplomacy isn’t just about reactors—it’s about leverage. The country’s Treaty of Tlatelolco (which declares Latin America a nuclear-weapon-free zone) has long been a cornerstone of regional security, but Argentina’s expanding civilian program raises questions about proliferation risks. The U.S. Is walking a tightrope: it needs Argentina’s cooperation to counter China’s influence, but it also can’t afford to be seen as enabling a potential nuclear-capable state.
Here’s the deeper game: Argentina’s nuclear expansion could force the U.S. To rethink its stance on the Treaty on the Prohibition of Nuclear Weapons (TPNW), which Argentina signed in 2017. If Buenos Aires pushes for stricter non-proliferation controls in the region, it could create a rift with Brazil and Mexico—both of which have resisted the TPNW. Meanwhile, China’s CNNC is quietly negotiating with Argentina to extend its uranium enrichment capabilities, a move that would directly challenge U.S. Export controls.
| Entity | Nuclear Reactors in Operation | Planned SMR Projects | Key Foreign Partners | Debt to Nuclear Suppliers ($B) |
|---|---|---|---|---|
| Argentina (CNEA) | 3 (Atucha I, Atucha II, Embalse) | 2 (CAREM-25, potential U.S. SMR) | China (CNNC), Russia (Rosatom), U.S. (NuScale) | $1.2 |
| Brazil (Eletronuclear) | 2 (Angra I, Angra II) | 1 (Angra III, delayed) | France (EDF), China (CNNC) | $0.8 |
| Mexico (CFE) | 0 | 1 (Proposed SMR with U.S. Firms) | U.S. (Westinghouse, GE Hitachi) | $0 |
| Chile (CCHEN) | 0 | 1 (Proposed SMR with China) | China (CNNC), Canada (Ontario Power) | $0.3 |
The Domino Effect: What Happens If Argentina Chooses China?
The workshop’s outcome hinges on one critical question: Can the U.S. Offer Argentina a better deal than China? Beijing’s approach is straightforward—low-interest loans, technology transfers, and no strings attached. The U.S., however, is constrained by its own export controls and congressional oversight. If Argentina leans toward China for its next reactor, it could trigger a regional cascade: Brazil might accelerate its Angra III project with CNNC, and Chile could abandon its U.S.-backed SMR plans.
But there’s a silver lining for Washington. Argentina’s nuclear sector is highly fragmented, with CNEA competing against private firms like INVAP, which has ties to both U.S. And European firms. The U.S. Could exploit this fragmentation by offering targeted financing for SMRs—positioning them as a “neutral” alternative to China’s state-backed reactors.
“The U.S. Has a window here to position SMRs as a ‘third way’—neither fully Western nor fully aligned with China. But it needs to move fast. Argentina’s political cycle is volatile, and if Milei’s government perceives the U.S. As offering empty promises, it will default to Beijing.”

The Long Game: What This Means for Global Security
The workshop’s broader implication is a test of whether Latin America can become a battleground for nuclear energy dominance—or if it can carve out a neutral path. For now, Argentina’s nuclear strategy is a microcosm of the global energy transition: a mix of geopolitical maneuvering, economic pragmatism, and technological competition. The U.S. And China aren’t just selling reactors; they’re selling access to their respective blocs.
Here’s the bottom line: If Argentina succeeds in balancing its partnerships, it could set a precedent for other Latin American nations. But if it tilts too far toward China, it risks becoming a pawn in a larger game—one where the real stakes aren’t just energy, but the future of regional sovereignty.
The workshop’s final communiqué will be watched closely. Will it be a U.S. Victory? A Chinese win? Or will Argentina pull off the impossible—playing both sides while maintaining its nuclear independence? One thing is certain: the nuclear chessboard in Latin America just got a lot more crowded.
What do you think: Can the U.S. Outmaneuver China in Argentina’s nuclear sector, or is this just another chapter in Beijing’s quiet takeover of Latin America?
