Japan's PM Kishida strengthens ties with South Korea amid North Korea threats.

Japanese Prime Minister Fumio Kishida visited South Korean President Yoon Suk Yeol in Seoul to strengthen ties amid nuclear threats from North Korea and China's increasing assertiveness. The focus of the summit will likely revolve around security cooperation, but historical disputes between the two countries threaten to cast a shadow over the blossoming ties. South Korean officials hope Kishida will offer some political support, but few expect any further formal apology for historical wrongs. Kishida has invited Yoon to the Group of Seven summit set for later this month in Japan and will hold trilateral talks with the U.S. on the sidelines.
