President Trump has readied a tariff strike against South Korea, threatening 25% duties on major exports following what he characterizes as a breakdown in trade agreement implementation. The announcement targets automobiles, lumber, and pharmaceutical products.
The disputed agreement was finalized between Trump and South Korean President Lee Jae Myung in October 2024, featuring provisions for reduced American tariffs in exchange for Korean investment commitments. However, disputes about ratification requirements have prevented full enactment.
Korean officials expressed surprise at Trump’s public threat, noting they received no advance diplomatic notification. The government is mobilizing responses including emergency consultations in Washington and expedited parliamentary action on five enabling bills.
South Korea’s export-oriented economy is particularly vulnerable to tariff changes, with the automotive industry representing the greatest exposure. When Trump’s tariff threat became public, shares in Korean carmakers fell sharply before recovering some ground.
Trump’s willingness to threaten tariffs against a key Asian ally demonstrates his continued emphasis on trade policy as a diplomatic tool. While some threatened tariffs are never implemented, international trade experts note that volatility itself imposes economic costs.
