Industry Minister Kim Jung-kwan said Thursday that he lodged a formal protest with U.S. Commerce Secretary Howard Lutnick over a White House announcement that, in Seoul’s view, oversold how far South Korea has committed to bankroll Alaska liquefied natural gas exports and U.S. nuclear reactor projects.

Kim told reporters the U.S. side’s public language “went far beyond what was agreed” during recent bilateral economic talks. The dispute lands at a sensitive moment: President Lee Jae Myung’s government is juggling security tensions on the peninsula with a promised wave of strategic investment in American energy and technology assets, yet insists every won must pass commercial reasonableness tests and full domestic procedures before contracts are signed.

What the factsheet implied—and what Seoul says is still open

A joint U.S.–Korea factsheet released alongside President Donald Trump’s presentation described the two countries as ready to “commence working on” the Alaska LNG venture once it clears the commercial standard written into a bilateral investment memorandum of understanding. Kim’s ministry said Thursday that phrase does not mean Seoul has decided to invest, let alone fixed a ticket size.

Officials reiterated that the Alaska project must still run through the MOU’s review process and that “nothing has been decided regarding whether to invest or the size of any investment.” That message contrasts with market chatter in Washington that portrayed Korean capital as a done deal for a pipeline-and-export scheme that U.S. promoters have pitched as a way to shrink the trade deficit.

On nuclear power, briefing materials referenced possible deployment of APR-1400 and AP-1000 reactor designs, but Seoul noted that even those talks lack finalized terms. Any reactor sale would need separate safety, financing, and host-community approvals in both countries.

Caps and staging rules

South Korean negotiators have publicly pointed to guardrails they secured earlier this year: an annual investment ceiling of $20 billion and an overall cap of $200 billion, with funds released in tranches tied to project milestones rather than upfront transfers. Kim’s protest is aimed at keeping those guardrails visible after a U.S. communications push that, in Seoul’s telling, sounded like a binding checkout.

Analysts in Seoul said the flare-up could complicate Lutnick-led working groups on shipbuilding and grid equipment even if the underlying MOU survives. Opposition lawmakers may use the episode to demand parliamentary hearings before any Alaska cheque is written, especially with household energy bills already central to local elections.

Next steps for negotiators

Kim did not specify whether Lutnick offered to revise the factsheet, but he said Seoul would continue to coordinate through existing industry channels rather than pausing unrelated export talks. U.S. Embassy officials in Seoul had no immediate comment beyond pointing to the published White House materials.

For Korean utilities and construction firms, the practical question is when due diligence on Alaska gas economics resumes—and whether Washington accepts that “commence working on” means spreadsheets and legal review, not a ribbon-cutting. Until then, Kim’s protest marks the clearest public break yet between the two capitals on how to describe the same sentence on paper.
