The real story is not being reported is what President Moon wants from the Biden administration in return for these investments. My guess will be he wants the U.S. to be more flexible on sanctions to jump start his North Korea engagement policy:
The United States is the world’s leading technology and innovation hub, but it is not a leader in the high-tech supply chain, mostly relying on Asian countries for essential items, such as semiconductors and batteries for electric vehicles.
In the face of growing challenges from China, U.S. President Joe Biden wants to revitalize the domestic manufacturing capacity amid the global chip crisis and a looming shortage of batteries, and he is expected to welcome a series of announcements of massive investment plans by Korean companies ahead of and after his summit talks with South Korean President Moon Jae-in on Friday.
