WASHINGTON (AP) — President Joe Biden is set to welcome the leaders of Japan and South Korea for the first summit of his presidency at the Camp David presidential retreat. Biden’s meeting on Friday with South Korean President Yoon Suk Yeol and Japanese Prime Minister Fumio Kishida comes as the United States aims to further tighten security and economic cooperation between the two countries. Historically frosty relations between South Korea and Japan have rapidly thawed over the last year because of Seoul and Tokyo’s shared concerns about China’s assertiveness in the Pacific and North Korea’s persistent nuclear threats. Biden is looking to use the summit to urge the leaders to turn the page on their countries difficult history.
