President Joe Biden is set to host Japanese Prime Minister Fumio Kishida for talks on the delicate security situation in the Pacific and for a glitzy state dinner. He is honoring a leader who has been one of Biden’s strongest allies in the face of international crises. Kishida’s official visit Wednesday completes the administration’s feting of the leaders of the Quad, the informal partnership between the U.S., Japan, Australia and India that the White House has focused on elevating since Biden took office. The leaders are expected to announce plans to upgrade U.S.-Japan military cooperation. Both sides are looking to tighten cooperation amid concerns about North Korea’s nuclear program and China’s increasing military assertiveness in the Pacific.
