Trump Accuses South Korea of Breaking Promise, Threatens 25% Tariff Punishment

Donald Trump has accused South Korea of breaking its promises and threatened to punish Seoul with 25% tariffs on major exports including automobiles, lumber, and pharmaceuticals. The president’s announcement specifically blamed Korea’s legislature for failing to enact a trade agreement both countries negotiated last year.
The trade framework was finalized in October 2024 following negotiations between Trump and South Korean President Lee Jae Myung, featuring reciprocal concessions including reduced US tariffs on Korean vehicles. However, disagreements about whether legislative ratification is required have prevented full implementation.
South Korea’s presidential office maintains it received no advance warning of Trump’s tariff threat through diplomatic channels. Officials are scrambling to respond, dispatching the trade minister to Washington while working with parliamentary leaders to expedite relevant legislation.
The potential economic impact is substantial, particularly for the automotive sector which accounts for 27% of South Korean exports to the United States. When Trump’s threat became public, shares in Korean carmakers fell sharply before recovering some ground as investors assessed the likelihood of implementation.
This latest tariff threat exemplifies Trump’s continued reliance on trade policy as a foreign policy instrument, following recent warnings to Canada and European nations. International trade experts express concern that the unpredictability creates business uncertainty and market volatility regardless of whether specific threats are carried out.
