South Korea unveiled plans to spend roughly $450 billion to build the world’s biggest chipmaking base over the next decade, joining China and the U.S. in a global race to dominate the key technology.

Samsung Electronics Co. and SK Hynix Inc. will lead more than 510 trillion won of investment in semiconductor research and production in the years to 2030 under a national blueprint devised by President Moon Jae-in’s administration. They’ll be among 153 companies fueling the decadelong push, intended to safeguard the nation’s most economically crucial industry. Moon will get a briefing from chip executives on the initiative Thursday during a visit to the country’s most advanced chip factory, a Samsung plant south of Seoul.

The investment comes at a time when the U.S., China and the European Union seek to shore up their semiconductor capabilities after a global chip shortage exposed a reliance on just a handful of Asian manufacturers and hobbled efforts to repair pandemic-scarred economies. The shortages are now spreading from autos to smartphones and displays, elevating semiconductors onto the agendas of governments from Washington to Brussels and Beijing.
