South Korea's prime minister plans to visit Japan next week in what would be the highest-level trip since Tokyo imposed export curbs in a deepening trade and diplomatic row, his office said Sunday.

Lee Nak-yon, whose trip is scheduled for Oct. 22-24, will attend Emperor Naruhito's enthronement ceremony on behalf of President Moon Jae-in, his office said in a statement.

Lee is likely to hold talks with Prime Minister Shinzo Abe, which would mark the highest-level dialogue since tensions flared up last year over the issue of Japan's use of wartime labor.
