Overview
- South Korea and the United States will hold a two-day inaugural meeting in Seoul on June 2-3 to begin formal negotiations to implement the Joint Fact Sheet from the October 2025 summit.
- The talks will address Seoul's push for nuclear-powered submarines, including where vessels would be built, with Seoul favoring domestic construction and Washington historically favoring U.S. yards.
- A central item is revising the U.S.-ROK civilian nuclear cooperation '123' framework to allow uranium enrichment and spent fuel reprocessing for peaceful use, a change U.S. officials link to strict nonproliferation safeguards.
- U.S. delegates led by Under Secretary Allison Hooker will join South Korea's team led by First Vice Foreign Minister Park Yoon-joo and officials from defense, energy, trade, and safety agencies, with working groups expected after the kickoff.
- The talks tie to broader economic and political terms in the Joint Fact Sheet, including Seoul's $350 billion investment pledge for tariff concessions and U.S. concerns about fair treatment of American firms and information-security rules that could affect alliance cooperation.
