トランプ大統領は、2026年1月27日のTruth Socialへの投稿で、韓国は10月に米国と結んだ貿易協定を守っていないため、自動車、木材、医薬品及びその他全ての相互関税に対する韓国の関税を15％から25％に引き上げると述べた。

Our Trade Deals are very important to America. In each of these Deals, we have acted swiftly to reduce our TARIFFS in line with the Transaction agreed to. We, of course, expect our Trading Partners to do the same.
South Korea’s Legislature is not living up to its Deal with the United States. President Lee and I reached a Great Deal for both Countries on July 30, 2025, and we reaffirmed these terms while I was in Korea on October 29, 2025. Why hasn’t the Korean Legislature approved it?
Because the Korean Legislature hasn’t enacted our Historic Trade Agreement, which is their prerogative, I am hereby increasing South Korean TARIFFS on Autos, Lumber, Pharma, and all other Reciprocal TARIFFS, from 15% to 25%. Thank you for your attention to this matter!
DONALD J. TRUMP
PRESIDENT OF THE UNITED STATES OF AMERICA
