In July 2025, during the US-South Korea summit, Donald Trump and Lee Jae-myung verbally agreed that South Korea would provide a $350 billion investment package into the US economy in exchange for avoiding US-imposed tariffs on key exports (e.g., automobiles, semiconductors, and steel).
After the summit, however, Trump added a new condition: the entire amount to be prepaid as an upfront cash transfer. In response, South Korea has sought to renegotiate the terms, including proposing a currency swap, and is awaiting a reply from the US.
