SK Group Chairman Chey Tae-won urged South Korea’s public and private sectors to accelerate semiconductor fab expansion, warning that the country’s memory-chip market share could shrink if China’s ChangXin Memory Technologies (CXMT), Yangtze Memory Technologies (YMTC) or U.S.-based Micron Technology adds capacity faster. Speaking in Shanghai on the 11th, Chey reaffirmed the planned 400 trillion won ($280 billion) Honam-Gwangju semiconductor cluster after visiting its proposed site at Gwangju Military Airport on the 9th. He said the project could proceed in parallel with the Yongin cluster and initially be built at about two-thirds of Yongin’s scale, with room to expand if land and demand allow. Chey said SK intends to more than double memory production capacity within five years and is reviewing overseas fab construction, including in Japan. He also defended SK’s investments in China, where the group has invested about $60 billion over 35 years, and said SK is pursuing an artificial intelligence research and development center in Shanghai focused on physical AI and biopharmaceuticals.
