Samsung Group said on Saturday it plans to invest a total of 450 trillion won ($310 billion) in South Korea over the next five years, including research and development, as the tech giant expands its semiconductor and AI operations.

The company said it will expand semiconductor production, with Line 5 at its new Pyeongtaek 2 plant expected to be fully operational by 2028. Samsung Electronics also plans to build a production line for the AI data center market in South Korea following its early-November acquisition of PlactGroup.

Samsung SDI is advancing plans for a next-generation domestic battery production facility, including solid-state batteries, with Ulsan under consideration as a potential site. Samsung Display aims to start mass production next year at its 8.6-generation OLED IT facility in Asan, South Chungcheong Province.
