South Korea’s 392 trillion KRW Chungcheong initiative is less about industrial expansion and more a sovereignty play to localize AI memory supply chains.

While reducing reliance on overseas OSATs, export controls from the U.S., Japan, and the Netherlands could inflate capex by 15–20%. TSMC, facing encroachment on its CoWoS dominance, may fast-track a second advanced packaging hub outside Taiwan, China. Within 18 months, Korea could achieve an integrated ‘memory-packaging-data center’ cluster—but risks overcapacity if U.S. HBM export restrictions to China tighten. This is geostrategic hedging disguised as industrial policy.
