President Biden has arrived in South Korea, kicking off a six-day visit to Asia that will also take him to Japan next week. Biden’s first stop today was a tour of a Samsung Electronics plant alongside newly inaugurated South Korean President Yoon Suk-yeol. Their meeting came after the White House said it expects North Korea to carry out a long-range missile test — or a nuclear test — during Biden’s trip.

Meanwhile, a top Chinese diplomat, Yang Jiechi, told Biden’s national security adviser Jake Sullivan in a phone call Wednesday, “If the U.S. continues to play the Taiwan card and head further on the wrong path, this will certainly lead to dangerous situations. … China will be steadfast to take actions that defend its sovereignty and security interests.”
