Victor Cha Proposes 'Economic NATO' to Shield Seoul's Nuclear Submarine Ambitions

Victor Cha proposes a collective economic deterrence pact to protect South Korea from Chinese retaliation over its nuclear submarine project. An 'Economic NATO' strategy.

They're shaking hands, but the fist is hidden behind a shield. Victor Cha, a prominent U.S. expert, just dropped a blueprint for a "collective economic deterrence" pact. It's a strategic move designed to protect South Korea from inevitable Chinese retaliation as Seoul moves forward with its U.S.-approved nuclear-powered submarine project.

In a Foreign Affairs article published on January 21, 2026, Cha argued that no single country can stand up to Beijing alone. His solution? A pact where coercion against one is treated as coercion against all. This framework mimics NATO's Article 5, ensuring that if China targets a single nation's industry, all allies respond with automatic counter-measures.

The timing is critical. President Donald Trump's recent green-lighting of South Korea's nuclear submarine fleet has Beijing on edge. Cha highlighted that the U.S., South Korea, and Japan control 327 goods—worth $23.19 billion—where China is over 70% dependent. He urged the Trump administration to use its 2027G7 presidency to institutionalize this deterrence instead of imposing tariffs on allies.
