Economic cooperation between South Korea and the United States has expanded through significant investments in technology and energy sectors. In early September 2026, four American companies in the semiconductor, advanced materials, and clean energy sectors announced a combined $2 billion in foreign direct investment into South Korea. Developments regarding South Korean investment in Texas gas-fired power plants have progressed. The South Korean government has officially designated a gas-fired combined-cycle power plant project in Encinal, Texas, as the first initiative under its $200 billion strategic investment plan in the United States. This project, known as ‘Project Star’ and estimated to cost approximately $22.3 billion, aims to provide electricity to nearby AI data centers and semiconductor manufacturing facilities. On September 29, 2026, President Donald Trump announced a broader $350 billion South Korean investment package tied to a 2025 trade deal. Key energy components include a $54 billion commitment to an Alaska liquefied natural gas (LNG) project involving an 807-mile pipeline, and an estimated $120 billion for eight large-scale nuclear power plants under ‘Project Power.’ A significant dispute has emerged regarding the Alaska LNG project. While President Trump has claimed South Korea would fund the pipeline and an additional $8.4 billion for enhanced oil recovery, South Korean officials have denied these specific commitments. On October 10, 2026, South Korean Industry Minister Kim Gyu-kwan clarified that no such commitment has been made, stating that any potential participation would only be considered after a thorough economic feasibility study. ~~This follows previous warnings from South Korean authorities that investment depends on~~ On October 13, 2026, White House Press Secretary Katie Zakariou reiterated the ~~lead developer,~~ figures, stating South Korea will invest $54 billion in the ~~Glenfarne Group, reaching~~ Alaska LNG pipeline and terminal, part of a ~~final investment decision.~~ broader energy package totaling up to $200 billion.
