South Korea has pushed back against U.S. President Donald Trump's claim that an Alaska liquefied natural gas (LNG) investment exceeding $50 billion has been finalized, saying the project can proceed only after commercial viability is confirmed and South Korean legal procedures are followed. The dispute emerged as the two countries finalized a $200 billion U.S. investment program, worth 272 trillion won, 14 months after reaching a tariff agreement under which Washington agreed not to raise tariffs above 15%. President Lee Jae-myung rejected Trump's presentation of the Alaska project as settled, while Industry Minister Kim Jung-kwan said the announcement marked the start of further negotiations. The joint fact sheet did not include the figure exceeding $50 billion, and talks on the separate $150 billion MASGA shipbuilding initiative have yet to begin in earnest. The investment package also includes an Encinal, Texas, gas combined-cycle power plant and plans for eight U.S. nuclear reactors. Seoul has said it will assess the Alaska project's economics and legal requirements before committing, while an initial $2.4 billion remittance for the Texas plant is underway.
