South Korea Pushes $350 Billion Investment Bill After Supreme Court Blocks Trump Tariffs
Updated (105 articles)
Supreme Court blocks Trump’s emergency tariff authority The U.S. Supreme Court on 21 Feb 2026 upheld a lower‑court ruling that the 1977 International Emergency Economic Powers Act does not justify the “reciprocal” 25 % tariffs imposed on South Korean steel, aluminum and autos [3]. The decision nullified the tariffs announced by President Trump on 27 Jan 2026 and forced the administration to issue a new 10 % global tariff proclamation [3]. This legal setback marks the most recent reversal in the trade dispute that began with Trump’s 25 % duties in early 2025 [3].
South Korean government vows close watch on U.S. moves Following the court ruling, the presidential office (Cheong Wa Dae) announced it will monitor any further U.S. policy shifts that could affect bilateral trade [1]. The statement reflects concern that Washington might replace the blocked tariffs with alternative measures [1]. Officials emphasized that monitoring will be continuous as the trade environment remains volatile [1].
National Assembly proceeds with $350 billion investment bill On 21 Feb 2026, rival parties in the National Assembly confirmed they will continue processing the special legislation that obliges South Korea to invest $350 billion in the United States, regardless of the tariff ruling [2]. People Power Party chair Kim Sang‑hoon asserted the court decision does not invalidate the investment commitment, and a Democratic Party senior official echoed the intent to keep the schedule unchanged [2]. Only the minor Jinbo Party called for an immediate halt, highlighting a rare dissenting voice [2].
Legislative timetable advances toward March vote The Assembly’s special committee, created after the February trade‑deal resolution, met first on 12 Feb 2026, set a hearing for the following Tuesday, and scheduled a plenary vote for 5 Mar 2026, with the committee remaining active until 9 Mar 2026 [2]. These dates indicate that the investment bill is on track for passage before the end of the month [2]. The timeline underscores the government’s determination to meet the pledge despite ongoing tariff uncertainties [2].
Diplomatic engagements reinforce investment review Vice minister Jeong Yeon‑doo met acting U.S. ambassador James Heller on 19 Feb 2026 to discuss implementation of the trade deal and pledged investment projects, agreeing to enhance communication [6]. A separate delegation led by Vice Trade Minister Park Jung‑sung arrived in Washington on 19 Feb 2026 to evaluate the commercial viability of prospective projects, especially in energy and power infrastructure [7]. Both meetings occurred after the Supreme Court decision and amid President Trump’s pressure on Korea following Japan’s $550 billion investment announcement [7].
