President Lee and I reached a great agreement between our two countries on July 30, 2025, and we reiterated the terms when I was in South Korea on October 29, 2025. Why did the South Korean Legislature not ratify it?
“Because the Korean legislature has not yet enacted our historic trade agreement, which is their prerogative, I hereby increase tariffs on Korean automobiles, lumber, pharmaceuticals and all other reciprocal tariffs from 15% to 25%.”
