US-South Korea Trade Tensions Escalate as $350 Billion Investment Fund Stalls Tariff Negotiations and Auto Exports Plummet

Listeners, welcome to South Korea Tariff News and Tracker. Today, September 10, 2025, we’re bringing the latest headlines and analysis on tariffs affecting South Korea and the United States, with a special look at the Trump administration’s evolving trade policy. A major story dominating the headlines is the ongoing standoff between the U.S. and South Korea over a $350 billion investment fund, which is a linchpin in the trade deal the two countries announced back in late July. According to the Korea Economic Daily and other sources, the agreement was supposed to deliver significant tariff relief for South Korean exports, specifically lowering tariffs on automobiles and most goods from 25% to 15%. This matched recent agreements the U.S. signed with Japan and the European Union. However, intense disagreements about the structure of the investment fund have put the negotiated tariff cuts on ice. South Korea’s presidential office warned on Tuesday that core elements of the deal are “at risk” and even the landmark Make American Shipbuilding Great Again project, which Seoul is pushing as a key benefit for both economies, could stall if these disputes aren’t settled. The U.S. insists on terms similar to those Japan accepted just last week—a $550 billion pledge with broad presidential control over allocations—but South Korean officials say their smaller economy can’t accept the same requirements. Meanwhile, South Korean automakers like Hyundai and Kia continue to face heavy pressure in the U.S. market. With the tariff on their vehicles still stuck at 25%, data from the Korea International Trade Association shows a sharp drop in auto exports to the U.S.—down 15.1% for the first seven months of 2025. Industry experts say Korean companies are struggling to absorb these extra costs and there’s already evidence of declining market share. Another major headline is fallout from a recent ICE raid at a Hyundai-linked plant in Georgia, where South Korean workers were detained, prompting swift diplomatic action and further straining trade talks. Elsewhere, President Trump’s approach remains aggressive, stating last week he would not hesitate to increase reciprocal tariffs to the 15–20% range across the board if partners resist U.S. demands. As of now, South Korea is still waiting for the executive order that would lower tariffs, and the $350 billion investment remains a sticking point. Trump’s insistence on aligning South Korea’s deal with that of Japan has created friction, and with neither side backing down, Korean companies are in limbo.
