North Korea, stuck in drawn-out diplomatic isolation, has stepped up efforts to reach out to ex-communist Mongolia.
Earlier this year, Pyongyang asked Ulan Bator to provide food aid.
Mongolia has also tapped business opportunities in the North and sought to use the bilateral relationship to enhance its role in regional security.
In November, Japan and North Korea had senior-level talks in the Mongolian capital about the issue of North Korea’s abduction of Japanese nationals.
Kyodo said the Mongolian leader may raise the issue in his meeting with the North’s leader.
Japan has urged North Korea to fully account for Japanese nationals it abducted decades ago. (Yonhap)
