SEOUL—President Biden began his three-day trip to South Korea with a visit to a Samsung Electronics Co. semiconductor plant, underscoring the technology ties between the countries as the U.S. seeks to strengthen supply chains and reboot its own manufacturing amid competition with China.
“These little chips—only a few nanometers thick—are the key to propelling us into the next era of technological development,” Mr. Biden said on Friday at the plant. He added, ”Our two nations work together to make the best, most advanced technology in the world, and this factory is proof of that.”
