In a surprising turn of events, Donald Trump has declared his intention to increase tariffs on various South Korean products, particularly automobiles, lumber, and pharmaceuticals. He accuses South Korea of failing to honor a trade agreement made last year, which has led to a significant drop in share prices for Korean car manufacturers.
Through a recent social media statement, the US President announced that the tariffs on South Korean imports entering the United States would jump from 15% to 25%. He expressed frustration over the lack of action from the "Korean Legislature" regarding what he called a "Historic Trade Agreement," emphasizing that it was within their rights but implying it reflected poorly on their commitment.
Trump stated, "South Korea’s Legislature is not living up to its Deal with the United States," although the administration has yet to officially implement these tariff changes. In response to Trump's announcement, South Korea’s presidential office revealed that they had not received prior warning about the proposed tariff increases. On Tuesday, they indicated that their trade minister, Kim Jung-kwan, who is currently in Canada, would travel to Washington to discuss this matter with US Commerce Secretary Howard Lutnick.
This shift in Trump's stance comes just months after a trade and security agreement was reached between Washington and Seoul, concluding a series of intense negotiations. This deal was finalized following a meeting in October between Trump and South Korean President Lee Jae Myung, which included promises of investment from South Korea alongside reductions in US tariffs.
However, since the deal's inception, it has remained mired in a state of legal ambiguity within South Korea. The presidential office maintained in November that parliamentary approval was unnecessary, claiming the agreement was more of a memorandum of understanding than a legally binding contract. In light of the recent developments, Finance Minister Koo Yun-cheol announced that the government would seek the parliament's cooperation on this issue later that day.
According to the terms of the previous agreement, the US was set to maintain tariffs of up to 15% on South Korean goods, including vehicles, auto parts, and pharmaceuticals. Notably, this arrangement had already reduced the previously high tariffs on South Korean cars from the 25% rate imposed by Trump earlier in 2025.
Should Trump follow through with his latest threat, it would reverse those beneficial changes. The automobile sector is crucial for South Korea, constituting about 27% of its exports to the US, which absorbs nearly half of the country's car exports. Immediately following Trump's announcement, shares of several South Korean automotive companies plummeted by as much as 5%.
Throughout his second term, Trump has frequently resorted to tariff threats as a key component of his foreign policy strategy. This approach has raised eyebrows among economists, with ongoing scrutiny from a pending case in front of the US Supreme Court. Trump's recent threats against South Korea add to a growing list of warnings directed at major trading partners.
Over the weekend, for instance, Trump cautioned Canada that if they proceeded with a trade deal with China, a staggering 100% tariff might be imposed on all goods crossing the border. Earlier in January, he also hinted at tariffs against multiple European countries until his administration secured the purchase of Greenland, although he later reassured that threat was not serious.
Josh Lipsky, who chairs international economics at the Atlantic Council, remarked that Trump’s latest actions towards South Korea reflect a growing impatience with how slowly Seoul is implementing the agreed-upon trade framework. He pointed out, "This serves as a reminder that the markets were overly optimistic in expecting tariff stability in 2026. People often say, 'Oh, but he doesn’t always follow through,' which can be true, but sometimes it isn't—and the mere volatility itself carries a significant cost."
