South Korea and the United States are finalizing implementation of Seoul's pledged $350 billion investment package under a trade deal reached last year that lowered U.S. tariffs on South Korean goods to 15%. Of the total, $150 billion is earmarked for shipbuilding, while the remaining $200 billion in strategic investments is still being defined. Projects under discussion include a 6.3-gigawatt combined-cycle gas power plant in Encinal, Texas, potentially backed by about $22.3 billion and developed through a bilateral special-purpose investment vehicle. The plan would begin with 1.4 GW of gas turbine facilities and later add 4.9 GW of combined-cycle capacity to supply Texas AI data centers and semiconductor plants. Seoul and Washington are also discussing up to eight U.S. nuclear reactors, including six using Westinghouse technology and two using a South Korean design. South Korea is separately negotiating a stake in Westinghouse, with media reports putting the possible investment at $2.25 billion to $3 billion for a 15% holding, depending on the company's valuation before a planned initial public offering. Other proposals include participation in the $44 billion Alaska LNG project, support for a U.S. plan to process 4,000 tons of spent nuclear fuel, and investment in carbon capture, utilisation and storage (CCUS), a system for managing industrial carbon emissions. South Korea's industry ministry has said the details have not been set, while Seoul has sought to include Alaska LNG in an investment memorandum without a binding commitment.
