South Korea’s cabinet approved a presidential decree to implement a $350 billion US investment plan, clearing a key administrative step in a trade framework designed to secure lower tariffs on Korean exports.
The plan stems from a trade agreement reached with Washington last year. It divides the investment into two major buckets: $200 billion for strategic US industries and $150 billion for shipbuilding cooperation.
The decree defines how the investment program will operate, including the standard for commercial reasonableness. Under the framework, a project must be capable of generating enough revenue to cover its principal and interest costs over the expected investment period.
AdvertisementSouth Korea will also create a state backed investment corporation to manage the program. The entity is expected to operate for 20 years and serve as the main vehicle for deploying capital into US projects.
The National Assembly passed the special investment bill in March with bipartisan support, after President Donald Trump threatened to raise tariffs on South Korean goods if Seoul failed to enact the framework.
The tariff relief is central to the deal. South Korea agreed to the investment plan in exchange for more favorable US tariff treatment, including lower duties on major exports such as automobiles.
The shipbuilding component is especially important. Washington has been trying to rebuild domestic shipbuilding capacity, while South Korea remains one of the world’s strongest players in the sector.
For investors, the commercial reasonableness test is the detail to watch. If enforced strictly, the program could direct capital toward projects with credible returns. If applied loosely, it risks becoming a subsidy tool for politically favored industries.
The broader market impact will depend on which projects receive early approval. Semiconductors, energy, artificial intelligence, pharmaceuticals, and shipbuilding are likely to be the main sectors investors track as the program moves from legislation to actual deployment.
The deal also changes the competitive setup for global manufacturers. Lower tariffs on South Korean exports could strengthen the position of companies such as Hyundai, Kia, Samsung, and SK Hynix in the US market, while adding pressure on rivals from Japan, Germany, and China.
