South Korean President Yoon Suk-yeol presented a plan to investors in New York on September 23, which marks the country's largest industrial bet in decades: to double semiconductor production within five years.
Samsung Electronics and SK hynix have committed to jointly invest over 800 trillion won – approximately $518–520 billion. These funds are intended for four new memory manufacturing plants, supply chain networks, and the infrastructure to support them. Considering expenses for AI data centers and other state 'megaprojects', the total investment is expected to exceed 880 trillion – 1 quadrillion won. Samsung and SK hynix together already account for about two-thirds of the world's memory chip production, so doubling their output is not only a Korean but also a global supply story. President Yoon referred to Samsung Chairman Lee Jae-Yong and SK Group Chairman Choi Tae-Won as 'national heroes' for their investment commitments.
The five-year goal was first detailed on June 29, 2026, as part of three megaprojects: semiconductors, physical AI, and AI data centers. The September summit in New York served as an international presentation of the same vision. Existing manufacturing clusters in Yongin and Pyeongtaek, both south of Seoul, will receive expedited timelines. New memory plants are planned for the Honam region and Gwangju, while a packaging hub is set for Chungcheong Province. Historically, South Korea's semiconductor industry has concentrated around the capital region, and the new facilities are intended to boost economic activity in less industrialized parts of the country. The Seoul metropolitan area also faces practical constraints: expensive land, a tight labor market, and zoning challenges.
