The Ministry of Trade, Industry and Resources of South Korea has postponed a closed-door briefing to parliament on the country’s U.S. investment projects, offering no explanation for the delay. The session was meant to outline the first U.S. investment project under the bilateral agreement signed last year.

In October, Seoul and Washington agreed to a $350 billion investment package in exchange for a reduction in U.S. tariffs. The plan includes $150 billion allocated to shipbuilding cooperation and $200 billion for projects across several strategic sectors.

The ministry asked the trade and finance committees to defer the briefing and did not specify a reason. Observers said the postponement appears tied to unresolved issues in the final stages of talks with the United States.

The delay may affect plans to formalize the agreement early on Friday. A ministry official said discussions with the United States are ongoing.
