據彭博社報道，美國總統唐納·川普表示，因韓國國會尚未將兩國去年達成的貿易協議完成立法核定，美國正考慮將韓國商品的關稅從15%調升至25%，適用範圍涵蓋汽車、木材、醫藥等多個領域。川普近期亦對多國發出關稅威脅，包括若加拿大與中國簽訂貿易協議，將對加拿大產品課征100%關稅，同時可能對歐洲商品加征新關稅；其並表示，將對與伊朗進行商業往來的國家實施關稅措施。不過，相關關稅威脅目前尚未實際落實。

According to Bloomberg, U.S. President Donald Trump stated that the United States is considering raising tariffs on South Korean goods from 15% to 25%—covering automobiles, lumber, pharmaceuticals and other sectors—because the National Assembly of the Republic of Korea has not yet legislatively ratified the trade agreement reached by the two countries last year. Recently, Trump has also issued tariff threats to multiple countries, including a plan to impose a 100% tariff on Canadian products if Canada strikes a trade deal with China, and a potential new round of tariffs on European goods. He also said that tariff measures will be imposed on countries that conduct commercial transactions with Iran. However, none of these tariff threats have been officially implemented so far.
