South Korea’s two semiconductor giants, Samsung Electronics and SK Hynix, are preparing to announce investments projected between 1,000 and 2,000 trillion won, roughly $650 billion to $1.3 trillion, over the next decade.

What’s actually happening

President Lee Jae-myung’s office is hosting a briefing at the Blue House on June 29, where the investment plans will be formally unveiled at 2 p.m. local time. The event is part of what the government calls its “three mega projects” initiative, aimed at fostering balanced regional development across South Korea.

Samsung’s Executive Chairman Lee Jae-yong and SK Group Chairman Chey Tae-won are both expected to attend.

The investment targets are squarely focused on the AI era: new memory chip fabrication plants, AI data centers, and robotics infrastructure. The city of Gwangju is one of the key regions being targeted for development.
