South Korea Pushes $350 Billion U.S. Investment Bill After Supreme Court Blocks Trump Tariffs
Updated (71 articles)
Supreme Court Blocks Trump’s Emergency Tariff Authority On Feb 21 2026 the U.S. Supreme Court upheld a lower‑court ruling that the 1977 International Emergency Economic Powers Act cannot justify the “reciprocal” 25% tariffs imposed on South Korea and other allies, effectively nullifying President Donald Trump’s emergency tariff proclamation. The decision erased the 25% duties announced on Jan 27 2026 and removed the legal basis for the broader tariff strategy. In retaliation, Trump signed a new proclamation imposing a 10% worldwide tariff and warned of additional measures to replace the struck‑down duties [2].
National Assembly Advances $350 Billion Investment Bill Despite the court decision, South Korea’s National Assembly will keep the special committee’s timetable, with a hearing slated for Feb 26 and a plenary vote on March 5. People Power Party lawmaker Kim Sang‑hoon said the ruling “does not seem to constitute a requirement that can cancel South Korea's investments to the United States,” and a senior Democratic Party official confirmed no schedule change. The minor Jinbo Party called for an immediate halt, but the two major parties pledged to press forward unchanged [1].
Seoul Sends Working‑Level Team to Discuss Investment Projects On Feb 19 Vice Trade Minister Park Jung‑sung led a delegation to Washington to meet U.S. Commerce Department officials and assess the commercial rationality of Korean projects under the $350 billion pledge. Delegates emphasized energy development and power‑infrastructure as likely sectors for investment. The mission followed President Trump’s announcement of Japan’s $550 billion investment plan, which he used to pressure Korea to accelerate its own commitments [4].
Korean Press Highlights Tariff Ruling and Party Turmoil Yonhap roundup of Feb 21 front‑pages showed Hankook Ilbo and Korea Economic Daily featuring the Supreme Court decision as a headline story, while the Kookmin Daily and Donga Ilbo reported People Power Party chairman Jang Suk‑yeol’s refusal to cut ties with ex‑President Yoon Suk‑yeol. The Chosun Ilbo highlighted criticism of three Democratic Party laws as undermining legal foundations. These reports illustrate domestic political tension concurrent with the legislative push on the investment bill [3].

Jan 26 2026 – President Donald Trump posts on Truth Social that the United States will raise reciprocal tariffs and auto duties on South Korean goods from 15 % to 25 % because the Korean National Assembly has not ratified the trade framework, invoking an economic emergency to bypass Congress. He declares, “South Korea has not lived up to the trade deal reached last year.” [1][22][23]
Jan 27 2026 – A White House official tells Yonhap that South Korea has made “no progress” on its trade‑deal obligations, framing the tariff hike as a response to legislative delays; the South Korean presidential office replies that it has received no formal U.S. notice and convenes an emergency inter‑agency meeting led by policy chief Kim Yong‑beom. [18][25]
