Trump tariff warning resurfaces

South Korea is suddenly looking at Trump’s tariff threat in a different way. Back in January, the fight looked like a messy trade dispute over whether Seoul’s legislature had properly ratified a deal. Now it looks broader — and more political. Trump has just paired tariff pressure on Europe with a military drawdown in Germany over allied support in the Iran conflict, and that has people in Seoul wondering whether the same security-plus-trade playbook could be used on them too.

The thing coming back into view is Trump’s January 26 threat to raise tariffs on South Korean autos, pharmaceuticals, lumber, and other goods from 15% to 25%. He tied that move to Seoul’s failure to pass legislation implementing parts of the trade package he said he reached with Pre(en.sedaily.com)mplemented tariff schedule change — but the threat itself was enough to jolt markets and policymakers.

Because the new fear is not just “Trump might raise tariffs again.” It’s “Trump might use tariffs as leverage in a security dispute.” Seoul Economic Daily says the concern flared after Washington confirmed a plan to cut about 5,000 U.S. troops from Germany while Trump also said EU passenger-car and (cnbc.com)once — defense and trade — after friction over cooperation in the Iran war.

The U.S. and South Korea struck a 2025 framework that lowered country-level tariffs from 25% to 15%, and Seoul also committed to a $350 billion U.S. investment package.

In Seoul, there was already speculation that Washington’s anger also touched Korean regulation of U.S. tech firms, especially after the Coupang data-breach investigation.
