South Korea Faces US Push to Expand $350B Investment Pact
Why is South Korea's $350 billion US investment deal in trouble?
South Korea's trade ministry confirmed Tuesday that Washington is demanding more than the pledged $350 billion in U.S. investment, straining the deal ahead of a September 17 parliamentary briefing.
Key numbers
| Original investment pledge | $350Bset in 2025 deal |
|---|---|
| Strategic industries portion | $200Bof $350B total |
| Shipbuilding portion | $150Bof $350B total |

What happened
South Korea's trade ministry confirmed Tuesday that Washington is demanding more than the pledged $350 billion in U.S. investment, straining the deal ahead of a September 17 parliamentary briefing. A lawmaker said the U.S. wants Seoul to help fund three energy projects — a Texas gas plant, a nuclear reactor program, and an Alaska pipeline — that together could exceed the $200 billion set aside for strategic industries. Negotiators are weighing whether to back two of the three projects or scale each one back. Trade Minister Kim Jung-kwan returned to Washington on September 10 for a final push before the briefing.
Why it matters
South Korea's $350 billion pledge was the price of cutting U.S. tariffs on its exports to 15%, and a bigger bill now would mean more Korean cash flowing into American factories, power plants and shipyards instead of at home. If Seoul refuses, Washington has previously threatened to raise tariffs back up, which would hit Korean automakers, chipmakers and other exporters that ship goods to the U.S.. The outcome also sets a precedent other countries with similar U.S. investment pledges, including Japan and the European Union, are watching closely.
