South Korean President Moon Jae-in on Tuesday told Prime Minister Shinzo Abe that he will raise the issue of Japanese nationals abducted by North Korea decades ago at his historic summit with the North's leader later this week.

During a phone conversation with Abe, Moon said he intends to tell Kim Jong Un that a "resolution of the abduction issue will help build peace in northeast Asia," the presidential office said.

The abduction issue is unlikely to be an official agenda item during the inter-Korean summit but will be touched on by the South Korean president during his conversation with Kim, a senior South Korean government official said.
