South Korea's spy chief has proposed a summit of the leaders of the United States, Japan and the two Koreas during the Tokyo Olympics next year, the Chosun Ilbo newspaper reported Wednesday.

Park Jie-won made the proposal in Japan, where he arrived Sunday for his first trip as head of the National Intelligence Service (NIS) with the aim of improving relations strained by a feud over compensation for Koreans who worked for Japanese firms during Tokyo's 1910-45 colonial rule of the Korean Peninsula.

Park suggested the summit during a Tuesday meeting with Prime Minister Yoshihide Suga, saying it could take up the issues of North Korea's denuclearization and the abduction of Japanese citizens by North Korean agents, the newspaper said.
