Trump Threatens to Double Tariffs on Korea if It Balks, Target Unclear, Amid $50 Billion-Plus Alaska LNG Talks

Trump did not say what he would double, and the two readings carry different prices ^[19]. Korea pays a 12.5% forced-labor tariff under Section 301 ^[18]. Doubled, that is 25%, exactly the rate Korea paid before it pledged $200 billion of U.S. investment last November in exchange for a cut to 15% ^[13][2]. Doubling the 15% deal rate would give 30% ^[3]. Washington political circles assumed the threat ran through Section 301, according to Seoul Economic Daily ^[16].

Section 301 can also take Korea back to its deal rate with no threat at all. USTR has signaled overcapacity tariffs on top of the forced-labor levy, and 2.5 more points would leave Korea at the same effective 15% it carried under the reciprocal tariffs ^[18]. The Supreme Court struck those down on Feb. 24 ^[17].

The quarrel is over what Seoul signed. "I didn't announce it prematurely," Trump said on Oct. 2 ^[6]. "If Korea doesn't want to, that's fine with me," he said. "We'll just charge them more." ^[7] Lutnick put the stake at "more than $50 billion" ^[10], on its own at least a quarter of the November pledge ^[1]. Seoul describes something smaller. Lee Jae-myung wrote that Korea agreed to begin "working" on Alaska LNG on the premise that its commercial viability is confirmed ^[11]. He added that nuclear plants need viability guaranteed plant by plant ^[12]. State Department spokesman Tommy Pigott called the projects a genuine "win-win" and, asked about the gap between the two accounts, said what mattered was that an agreement had been reached ^[14].

China is on the same list of 60 economies paying forced-labor tariffs ^[17]. The difference is direction. After their Sept. 24 White House meeting, Trump and Xi Jinping agreed to refrain from escalating ^[5]. The new pressure falls on countries that "have little choice but to defer to Washington," according to the report ^[5]. Seoul Economic Daily ties the timing to the midterms: Democrats' odds of taking the House have grown and close Senate races have multiplied ^[2]. It says the asks are help with U.S. diesel prices and investment in congressional districts ^[3]. Its detailed reporting covers Korea and does not set out what Japan or Europe were asked to do on diesel.

So Trump is spending tariff leverage on Korea, Europe and Japan ^[1] and none, for now, on the country he just agreed a truce with ^[5]. Seoul, for its part, is not committing capital to Alaska before the viability test is met ^[11].

The threat can resolve in one of three ways. Seoul accepts Washington's account and nothing is levied; USTR doubles the 12.5% and the November deal's tariff cut is gone; or the remark stays a campaign line through Nov. 3 while the State Department's position that an agreement was reached stands ^[14]. I think the third is likeliest before the vote, because a 25% rate on Korea would cut against the district investment Trump is campaigning on ^[3]. The counter-case is that overcapacity tariffs are already signaled ^[18], so an increase can arrive as a routine USTR notice with no fresh announcement. A notice putting Korea above 15% before Nov. 3 would prove that view wrong.
