Trump scales back Korea military drills over stalled $350B investment pledge

President Donald Trump's order to scale back joint military exercises with South Korea reflects not only his desire to re-engage North Korea diplomatically but also a broader administration frustration with Seoul's failure to deliver on a $350 billion investment commitment made more than a year ago. Nearly twelve months after the pledge, South Korea has yet to announce a single project.

'The Slowest Negotiators Ever'

According to Politico, a person familiar with U.S.-South Korea investment discussions described Seoul's negotiating team as "the slowest negotiators ever," saying talks have progressed far more slowly than the Trump administration expected. The report, published on August 17, said Trump's decision to reduce military drills was driven in part by "administration-wide economic frustrations" with South Korea's pace.politico

Commerce Secretary Howard Lutnick met on Monday with South Korea's Industry Minister Kim Jung-kwan in Washington to discuss the investment delays. Kim had made what Korean media described as an emergency trip to the United States, arriving on August 16 and telling reporters that "various and specific practical issues are emerging at the last minute" as negotiations enter their final stage.chosun+1

Victor Cha, the Korea chair at the Center for Strategic and International Studies, said South Korea was misreading the political moment. "They seem to want to perfect every detail before making any announcement," Cha told Politico. "That's just not the way it works in a Trump administration."politico

Memory Chips Add New Friction

Washington has complicated Seoul's investment planning by demanding that Samsung Electronics and SK hynix ↗ 1.92% prioritize building memory chip production facilities in the United States as the first announced project. Seoul had been preparing an energy-sector investment as its inaugural commitment, but Lutnick publicly singled out the two chipmakers on July 9, saying he wanted them "to build production facilities" in the United States.koreajoongangdaily

The Korea JoongAng Daily reported that a closed-door Blue House meeting last week concluded that U.S. memory chip investment would pose "practical difficulties," given the companies' existing commitments to build facilities in South Korea's Honam region. A ruling bloc official said, "It is as if the goalposts for U.S. investment have been moved."koreajoongangdaily

Security and Trade Increasingly Linked

The investment standoff has spilled into security discussions. Follow-up talks on nuclear-powered submarines and revisions to the bilateral nuclear cooperation agreement, initially expected in July, have stalled. Trump also publicly criticized South Korean President Lee Jae Myung for declining to assist with U.S. operations against Iran, asking on Monday, "Why are we involved in helping you?"politico+1

By contrast, Japan — which pledged $550 billion — has already finalized six investment projects. South Korea's trade minister said a first project announcement could come in late August or early September, but with the deadline for the overall $350 billion pledge set at January 2029, the gap between Washington's expectations and Seoul's pace continues to widen.chosun+1

"The president loves leverage," one person familiar with the discussions told Politico. "You get leverage by being willing to use it, and Trump does."politico
