President Donald Trump is intensifying pressure on South Korea to invest in the Alaska liquefied natural gas project, linking the dispute to broader trade tensions. South Korea, however, is maintaining that commercial viability must be assessed before any investment decision, creating a gap between Seoul’s cautious position and Washington’s effort to portray participation as settled.
Asked at the White House whether an announcement had been premature because South Korea had not agreed to the project, Trump rejected that characterization. He said Korean representatives had been present, according to Maeil Shinmun. The report also raised concern that the disagreement could complicate security consultations that had gained momentum alongside investment negotiations.
Cost concerns complicate political pressure
The pressure comes as questions about the project’s economics persist inside the United States. Kyunghyang Shinmun reported that a study submitted to the Alaska Legislature in December identified high capital costs and the risk of further cost increases as major obstacles. The report said responsibility for overruns had not been determined and that the project’s cost estimate lacked sufficient precision.
- South Korea’s position
- Commercial viability must be reviewed before an investment decision
- Risk identified in Alaska
- High capital costs and uncertainty over responsibility for overruns
- Source of pressure
- Trump has tied an agreement to the possibility of higher tariffs
Trump’s leverage is trade policy. Kyunghyang reported that he warned tariffs could be doubled if an agreement was not reached, although the precise conditions attached to that warning require careful distinction from any completed investment commitment. That uncertainty matters because a political announcement does not resolve financing, risk allocation or the Korean government’s review of feasibility.
For South Korea, the immediate issue is whether commercial due diligence can remain separate from tariff and security negotiations. A decision made under pressure could expose Korean participants to uncertain costs, while resistance could increase friction with Washington. Attention will center on whether the two governments define the project’s financing and liability terms, and whether either side formally confirms that South Korea has committed to invest.
