Trump Presses South Korea Over Disputed Alaska LNG and Energy Investment Pledges

U.S. President Donald Trump warned South Korea that he would 'double it up' and charge higher penalties—widely interpreted as doubled tariffs—if Seoul does not sign on to the proposed $50 billion to $54 billion Alaska Liquefied Natural Gas (LNG) project. The dispute follows Trump's Oval Office announcement declaring South Korea had committed to the gigaproject as part of a broader trade and investment arrangement. South Korean officials, including President Lee Jae Myung and the Ministry of Trade, Industry and Resources, swiftly pushed back, noting that no formal investment decision or dollar amount has been approved and that participation remains strictly conditioned on commercial viability and domestic legal reviews.

// Background

The Alaska LNG project is an 800-mile (roughly 1,300 km) proposed pipeline designed to transport natural gas from the North Slope to Southcentral Alaska for liquefaction and overseas export. Despite being pursued for decades, the gigaproject has repeatedly foundered due to immense capital costs and unresolved economics. Developer Glenfarne, owning a majority share alongside the state-owned Alaska Gasline Development Corp., has faced shifting deadlines for a final investment decision. State-level legislative efforts to grant property tax breaks stalled in Juneau after disagreements over oil company corporate taxes.

// Key Developments

• President Trump warned he did not 'jump the gun' and threatened to double charges or tariffs if South Korea delays signing onto the Alaska LNG project.
• South Korean President Lee Jae Myung clarified that no investment has been finalized, emphasizing that the project must meet commercial viability preconditions and pass domestic legal procedures.
• Discrepancies expanded further after Trump announced an additional $8.4 billion enhanced oil recovery project, which South Korea's Industry Ministry said was never part of bilateral agreements.
• The 800-mile pipeline, estimated to cost up to $54.5 billion, remains hindered by unresolved final investment decisions and contentious Alaska state tax exemption debates.
• Critics and political observers characterized the White House event as a campaign effort designed to bolster Alaska Republican incumbents ahead of general elections.
