President Joe Biden's six-day trip to South Korea and Japan aims to build rapport with the Asian nations’ leaders. Biden will also be trying to send an unmistakable message to China that Russia’s faltering invasion of Ukraine should give Beijing pause about its own saber-rattling in the Pacific. Biden departs Thursday and is set to meet newly elected South Korean President Yoon Suk Yeol and Japanese Prime Minister Fumio Kishida. Their talks will touch on trade, the global supply chain and North Korea’s nuclear program. Biden will also meet with leaders of the alliance known as the Quad, which includes Japan, Australia and India.
