South Korea Cabinet Approves Decree for $350 Billion U.S. Investment Plan

South Korea has taken a major step in implementing its $350 billion investment commitment to the United States after the Cabinet approved a presidential decree on June 9, 2026. The decision creates the legal framework needed to launch one of the largest overseas investment programs ever backed by Seoul. The package includes $200 billion for strategic U.S. industries and $150 billion for shipbuilding cooperation, strengthening economic ties between the two countries and supporting long-term industrial growth.

South Korea Clears Final Legal Hurdle for $350 Billion U.S. Investment Plan

The newly approved decree sets out how investment projects will be reviewed and managed. One of the most important provisions defines “commercial reasonableness,” requiring projects to generate sufficient revenue to repay both principal and interest costs over their expected lifespan. The framework is designed to ensure that investments remain financially viable while meeting broader economic goals.

The decree follows legislation passed by South Korea’s National Assembly in March 2026. The law established the legal basis for the investment package and approved the creation of a state-backed investment corporation with capital of 2 trillion won, equivalent to approximately $1.4 billion.

Why Is South Korea Investing $350 Billion in the United States?

The investment commitment is part of a broader trade agreement between Seoul and Washington. Under the arrangement, South Korea agreed to invest $350 billion in return for improved tariff treatment on key exports, including automobiles and industrial products. Earlier this year, U.S. officials signaled that tariffs could rise from 15 percent to 25 percent if the agreement was not implemented.

The plan is also aimed at strengthening supply chains and expanding industrial cooperation in sectors that are considered strategically important. These include semiconductors, artificial intelligence, pharmaceuticals, energy, critical minerals, and quantum technologies.

Where Will the $350 Billion Be Allocated?

1. The package allocates $200 billion to strategic industries across the United States. These investments are expected to support advanced manufacturing, technology development, and supply chain resilience.
2. A further $150 billion has been reserved for shipbuilding cooperation. South Korean shipbuilders are among the world’s leading manufacturers, and the investment is expected to enhance collaboration in commercial and industrial maritime projects.

How Will the Investment Program Be Managed?

The investment plan will be overseen by a dedicated corporation established under the new legislation. The entity is expected to operate for 20 years and manage project selection, financing, and oversight.

According to Reuters and The Korea Times reports, Government officials have stated that project schedules and investment timelines will be coordinated with U.S. counterparts. The structure is intended to balance commercial returns with long-term economic and strategic objectives.

Final Takeaway: What Comes Next for South Korea and the United States?

With Cabinet approval now secured, South Korea can move forward with implementing the investment framework. The next stage involves identifying eligible projects, finalizing investment schedules, and coordinating with U.S. authorities. The $350 billion initiative represents one of the largest international investment commitments in South Korea’s history. It is expected to deepen economic cooperation, support industrial expansion, and strengthen bilateral trade relations across multiple high-growth sectors over the coming decades.
