South Korea Accelerates Semiconductor Expansion Amid AI Export Control Setbacks

South Korea is in the final stage of planning a major new semiconductor expansion, with the government, Samsung Electronics and SK Hynix coordinating to speed up construction of advanced chip clusters, notably the Yongin site. The push is driven by surging artificial‑intelligence demand; SK Hynix is reportedly considering moving the completion of its fourth wafer fab forward by a decade, and the overall timeline for the cluster could be advanced from a 2044 target to around 2034.

At the same time, a U.S. export‑control order forced Anthropic to suspend foreign access to its most advanced AI models. The directive hit SK Telecom, South Korea’s largest carrier, which had just announced a gigawatt‑scale AI cloud partnership with Nvidia. The loss of Anthropic’s models highlights regulatory uncertainty that could hamper South Korea’s AI infrastructure plans and its broader semiconductor strategy.

The combined developments underline the country’s effort to secure AI‑related chip supply while navigating growing geopolitical tensions over advanced AI technology.
