US Increases Tariffs on South Korea Amid Investment Delays

President Donald Trump declared on Tuesday that discussions will be held between the United States and South Korea following his unexpected move to raise tariffs on South Korean imports to 25%. Responding to inquiries about the increase, Trump stated, "We'll come to an agreement with South Korea," but refrained from providing additional specifics.

Jamieson Greer, the U.S. chief trade negotiator, indicated that the tariff was previously reduced from 25% to 15% contingent on South Korea committing $350 billion in investments in the U.S., easing access for American automobiles, and eliminating certain trade barriers. Greer emphasized that legislative action is still pending on South Korea's side to fulfill these commitments.

In a Monday social media post, Trump noted that the tariff hike was prompted by South Korea’s parliament not adhering to last year's agreement with the president. This unexpected announcement has left officials in Seoul scrambling to prepare for a possible economic hit to the export-centric nation.

Greer further pointed out the increasing U.S. trade deficit with South Korea, which reached $65 billion during the Biden administration, labeling it as "unsustainable." Legislation regarding the investment package remains stalled in South Korea’s parliament, with votes not expected until February. Five bills related to the U.S. investment initiative are pending, and the ruling party is aiming for swift approval.

Moreover, the U.S. has expressed concerns over South Korean regulations tightening oversight on digital services and online platforms, suggesting that these measures may disadvantage U.S. companies. Speculations arise that recent actions against Coupang, a U.S.-traded Korean firm, could have influenced the tariff increase, though South Korea’s Foreign Minister refuted any direct connection.

Earlier this month, South Korea’s Finance Minister mentioned that the investment initiative is set to commence soon; however, factors such as an impending U.S. Supreme Court ruling on tariffs and a depreciating Korean won may postpone the start until after mid-2026.
