The leaders of South Korea and Japan agreed to normalize an intelligence-sharing pact to strengthen joint deterrence against North Korea’s nuclear and missile advances, as they sought to improve strained relations at a bilateral summit in Tokyo on Thursday.

President Yoon Suk-yeol’s two-day visit to Japan to meet with Prime Minister Fumio Kishida marks the first time an ROK leader has visited the country for a bilateral summit in more than a decade. It follows the two sides’ agreement to resolve a dispute over Korean victims of Japan’s wartime forced labor.
