Donald Trump is encountering fresh challenges in his efforts to secure major investment commitments from key Asian allies, as South Korea and Japan signal concerns over the terms of their agreements with Washington, according to reporting from Bloomberg.
South Korea’s National Security Adviser, Wi Sung-lac, said in a Channel A News interview on Saturday that the country cannot realistically meet the $350 billion investment pledge agreed with the United States. “We are not able to pay $350 billion in cash,” Wi said, adding that Seoul’s position “is not a negotiating tactic.”
The investment pledge, part of a broader trade deal that lowers U.S. tariffs from 25% to 15%, remains a point of contention between Seoul and Washington. Trump has described these pledges as “up front,” but South Korean officials have raised concerns about their potential impact. In a Bloomberg News interview last week, South Korea’s Prime Minister Kim Min-seok noted that without a currency swap arrangement with the U.S., the investment could seriously strain the national economy, as $350 billion amounts to more than 80% of the country’s foreign reserves.
Visa issues are also complicating the implementation of planned U.S. investment projects, leaving them in limbo, according to Seoul. The government is reportedly exploring alternative solutions, with hopes for progress during the upcoming APEC Summit in Gyeongju.
Japan, meanwhile, has committed to a $550 billion investment vehicle to support U.S. trade interests, but the funding mechanism remains unclear. Over the weekend, Sanae Takaichi, a leading contender to head Japan’s ruling Liberal Democratic Party (LDP), suggested that the deal could be renegotiated if it fails to serve Japan’s interests. “We must stand our ground if anything unfair that is not in Japan’s interests comes to light in the process of implementing the deal,” Takaichi said.
U.S. Commerce Secretary Howard Lutnick reportedly prefers the South Korean investment be made in cash rather than loans. In Japan, a memorandum of understanding stipulates that the nation has 45 business days to provide funds for U.S.-selected projects, though Japan’s trade negotiator Ryosei Akazawa has indicated that much of the $550 billion mechanism will involve loans and guarantees, with only 1–2% constituting direct investment.
The LDP is scheduled to vote on its next leader on October 4, a decision that will shape Japan’s position in ongoing negotiations with Trump over trade and investment implementation.
Bloomberg’s reporting highlights the growing complexity of Trump’s push for large-scale Asian investments, as both South Korea and Japan weigh the economic and political implications of fulfilling the pledges.
