Efforts by the South Korean government to reduce the tariff hike imposed by US President Donald Trump last week appear to have failed.
The country’s trade minister told reporters in Seoul on the weekend that while some “unnecessary misunderstandings” had been resolved, but he and other officials had been unable to stop Washington increasing tariffs on Korean exports from 15% to 25%.
Minister of Trade, Industry and Resources Kim Jung-kwan, who flew back to Seoul on Saturday, said he met twice with US Secretary of Commerce Howard Lutnick in Washington on Thursday and Friday, but the “measures to raise tariffs [on Korea] have already begun.”

President Trump hiked tariffs on South Korean goods to 25% last week after asking, in a post on social media, why the Korean legislature had failed to approve the trade agreement reached last year with President Lee.
The trade, industry and resources minister plans to continue talks via video calls with Lutnick and other US officials, plus trade representative Yeo Han-koo has stayed in the US for a few more days to meet with his US counterpart Jamieson Greer and discuss bilateral issues.
“The Korean government will actively demonstrate its willingness to implement the Korea-US tariff agreement,” a senior official at the presidential office told Korea JoongAng daily on Sunday.
Focus on Assembly vote
The Korean delegation explained that they need the National Assembly to pass a special law on the massive investments — some $350 billion — it has vowed to make in the US, but the ruling Democratic Party’s chief policymaker Han Jeoung-ae has said that is not due to happen till late this month or early March.
Kim, the trade minister who returned to Seoul, said this is the key concern for US officials.
Han was quoted as saying the government’s hands were tied due to the lack of a legal basis for the deal. But they will try to keep to the National Assembly’s deadline with a vote at the end of this month.
“If the National Assembly follows the set timetable for the bill, I think negotiations between Korea and the United States will progress.”
But he suggested the government may need to consider other moves to show the United States that Korea is committed to keeping its side of the agreement.
The Koreans said last year that the huge amount pledged in October is a major risk for their economy and they would have to limit outlays to $20 billion a year, from mid-2026, to prevent a severe impact on the won, as their currency has been weak.
There is also uncertainty about the deal because the US Supreme Court has yet to rule on whether Trump’s tariffs were imposed legally.
In November, Supreme Court justices cast doubt on Trump’s authority to impose tariffs under the 1977 International Emergency Economic Powers Act (IEEPA), which contains no references to tariffs – only language on regulating imports during national emergencies declared by the US president.
Meanwhile, there have also been claims that Trump may have imposed the tariff hike because he was unhappy with recent South Korean regulatory actions against Coupang, a US-listed e-commerce company that has complained that the moves were unfair and discriminatory.
