South Korea is planning an approximately 800 trillion won ($518 billion) semiconductor investment hub in its southwestern region, as President Lee Jae Myung seeks to spread the benefits of the artificial intelligence boom beyond Seoul and strengthen the country’s position in the global chip industry.
The proposed complex is expected to involve Samsung Electronics and SK Hynix, two of the world’s leading memory-chip manufacturers.
The plan centres on the Honam region, including Gwangju and parts of North and South Jeolla provinces, which have historically attracted less industrial investment than the Seoul metropolitan area.
The government aims to develop the area into a second major semiconductor manufacturing centre, complementing existing and planned facilities around the capital.
The investment forms part of a broader industrial expansion that includes artificial intelligence infrastructure, data centres and robotics.
The government and companies are seeking to meet growing demand for advanced chips used in AI computing while encouraging more balanced economic development across the country.
Samsung and SK Hynix have outlined plans for major semiconductor investments in the southwest, including four fabrication plants.
The companies’ proposed spending could create construction and manufacturing jobs, attract suppliers and support local businesses.
However, the announced commitments are long-term plans rather than money already spent, and their implementation will depend on commercial conditions and infrastructure readiness.
Electricity and water supply are among the biggest obstacles. Semiconductor fabrication plants require large, reliable supplies of both resources, while the proposed complex could significantly increase demand in a region where infrastructure expansion remains necessary.
Analysts have also highlighted the need to develop skilled labour, housing and transport links to support a large industrial workforce.
Local opposition to new transmission lines and water infrastructure could complicate the timetable.
The government says regional energy resources could help meet some of the additional demand, but experts have warned that delays in infrastructure development could prevent the plants from operating at the intended scale by 2030.
The strategy also carries trade implications for South Korea’s relationship with the United States.
Washington has encouraged foreign chipmakers to expand domestic production, and analysts say the scale of planned investment at home could prompt renewed pressure on Korean companies to increase their US manufacturing commitments.
Both Samsung and SK Hynix already have significant US investment plans, including facilities intended to serve demand for advanced chips and AI-related technologies. Their challenge will be to balance domestic expansion with overseas production, access to major customers and exposure to shifting trade policies.
For South Korea, the proposed hub represents an attempt to turn the AI boom into a wider economic opportunity rather than allowing its benefits to remain concentrated around Seoul.
Its success will depend on whether the government and companies can deliver the necessary infrastructure, attract skilled workers and sustain investment while navigating international trade pressures.
