Presidential Policy Chief Eyes Jeolla Semiconductor Cluster
Samsung Electronics and SK Hynix are set to announce investment of more than 300 trillion won (approximately $215 billion) in a new semiconductor and AI infrastructure cluster in the Gwangju-South Jeolla region of South Korea at a public-private meeting hosted by President Lee Jae-myung at the Blue House on June 29, according to Seoul Economic Daily. The cluster will cover front-end memory chip production, back-end packaging, and AI data centers, directly targeting surging demand for AI chips including Samsung's HBM4, which it began mass-producing first in the world in April 2026 and whose sales already exceed $1 billion. The project, separate from the existing Yongin chip hub, supports the Lee administration's balanced regional development strategy and the formal launch of Gwangju-South Jeolla Special City on July 1.
What happened
Samsung Electronics and SK Hynix are expected to announce combined investment of more than 300 trillion won (~$215 billion) in a new advanced semiconductor cluster in the Gwangju-South Jeolla region at a public-private joint meeting hosted by President Lee Jae-myung at the Blue House on June 29, according to Seoul Economic Daily. A government-business signing ceremony is planned in Gwangju on June 30. The cluster will encompass front-end memory chip production lines, back-end packaging plants, and AI data centers, targeting surging demand for artificial intelligence chips (Seoul Economic Daily, Korea Times).
Policy context
The investment is a centrepiece of the Lee administration's "5 Poles, 3 Special Zones" strategy for balanced regional development - five super-regional economic blocs and three special self-governing cities. Kim Yong-beom, Chief of Policy for President Lee Jae-myung, publicly signalled the southwestern provinces covering Gwangju, North Jeolla, and South Jeolla as under serious consideration for a second semiconductor hub, citing the region's abundant electricity and water resources. The Gwangju-South Jeolla Special City formally launches on July 1, 2026 (Seoul Economic Daily).
Industry context
This is the second major South Korean semiconductor hub, separate from the Yongin, Gyeonggi cluster first announced in 2019. Samsung Chairman Jay Y. Lee visited the South Chungcheong production site on June 23 to inspect high-bandwidth memory (HBM) manufacturing. Samsung disclosed that global sales of its HBM4 - which it began mass-producing first in the world in April 2026 - have already surpassed $1 billion and are projected to exceed $10 billion by year-end. HBM4 is the memory technology at the centre of AI accelerator demand from customers such as Nvidia (Seoul Economic Daily).
AI infrastructure angle
The explicit inclusion of AI data centers in the Gwangju cluster makes this directly relevant to the global AI infrastructure buildout. South Korea's two leading chip companies are aligning major new capacity around AI-driven demand, a signal that HBM and AI-chip production will continue to expand outside the existing capital-region concentration.
What to watch
- •Official confirmation of figures and timelines at the June 29 Blue House meeting and the June 30 signing ceremony.
- •Whether the AI data center component attracts additional technology partners beyond Samsung and SK Hynix.
- •Follow-up announcements planned for next month covering Chungcheong and Gangwon regions, involving Samsung, SK, Hanwha, and HD Hyundai.
Scoring Rationale
Major semiconductor infrastructure announcement directly tied to AI chip demand: Samsung and SK Hynix combined 300+ trillion won (~$215B) cluster explicitly includes AI data centers and responds to HBM4/AI accelerator demand. Scale and AI relevance place this above a routine policy announcement, warranting a notable score.
