South Korean President Moon Jae-in is meeting today with U.S. President Joe Biden at the White House. It’s only the second time Biden has hosted a world leader in person, after a meeting with Japan’s prime minister in April. The South Korean leader is seeking U.S. help in securing vaccines; in exchange, Biden is reportedly seeking South Korean investment in U.S. semiconductor plants as the world faces a shortage of microchips. The two are also expected to discuss denuclearization of the Korean Peninsula.
