U.N. special rapporteur on North Korea Marzuki Darusman on Monday discussed Pyongyang's past abductions of Japanese nationals with Japanese ministers and relatives of abductees during his visit to Tokyo.

"Japan does not intend to close the window for dialogue with North Korea," Katsunobu Kato, state minister in charge of the abduction issue, said in his meeting with Darusman, which was open to media. "Japan will tackle the (issue) with ultimate efforts to bring back the abductees to Japan as soon as possible."

Darusman, the U.N. special rapporteur on human rights issues in North Korea, responded that "it would be of immense interest to expect dialogue between Japan and North Korea continues to take place."
