President Trump has threatened to impose 25% tariffs on South Korean imports including automobiles, pharmaceuticals, and lumber, claiming Seoul has failed to properly implement a trade agreement from 2024. The announcement specifically criticized South Korea’s legislature for not enacting the bilateral trade framework.
The disputed agreement was finalized after negotiations between Trump and South Korean President Lee Jae Myung in October 2024, including provisions for reduced American tariffs and increased Korean investments. However, disagreements about whether parliamentary ratification is required have left the deal in legal limbo within South Korea.
Korean officials were blindsided by Trump’s public announcement, receiving no advance warning through diplomatic channels. The government is responding by dispatching the trade minister to Washington for emergency talks while working with parliament to pass five bills that would enable promised investments.
South Korea’s automotive sector faces the greatest vulnerability to tariff increases, as it accounts for more than a quarter of Korean exports to the United States. The immediate market response saw significant stock price declines for Korean carmakers, though losses were partially recovered as traders assessed the situation.
Trump’s approach to trade policy continues to emphasize unpredictability and threats as negotiating tactics. While not all threatened tariffs are implemented, economists note that the volatility created by such announcements imposes real costs on businesses and markets attempting to plan for the future.
