South Korea’s US$518 billion semiconductor push aims to tap the artificial intelligence boom into a durable industrial advantage and keep up with leading rival China, according to observers.The plan is intended to secure supplies of advanced memory chips needed for AI data centres and computing infrastructure, while easing pressure on the Seoul metropolitan area by creating a second major chipmaking base in the country’s southwest.President Lee Jae Myung on Monday unveiled the government’s “Three Mega Projects” initiative, centred on semiconductors, physical AI and AI data centres, as part of a strategy to turn South Korea into a global technology powerhouse.Under the plan, Samsung Electronics and SK Hynix will invest a combined 800 trillion won (US$518 billion) in the southwestern region to establish a second major semiconductor production hub alongside the emerging Yongin semiconductor cluster near Seoul.Separately, SK Group, GS Group, Naver and other companies will also invest a total of 550 trillion won by 2029 to build large-scale AI data centres nationwide.The government will support the initiative by providing essential infrastructure, including electricity, water and industrial sites, and plans to offer discounted electricity rates for AI data centres.“These megaprojects represent South Korea’s efforts to maintain its technological edge in semiconductors over China and other competitors,” said Park Jae-guen, a renowned semiconductor expert at Hanyang University.
