SEOUL--North Korean leader Kim Jong Un is prepared to meet with Prime Minister Shinzo Abe within the next few months, a South Korean intelligence source said June 14.

Kim indicated his willingness to hold talks with the Japanese leader during the June 12 summit in Singapore with U.S. President Donald Trump, who raised the issue of Japanese abducted by Pyongyang decades ago, the source said.

Trump strongly urged Kim to hold talks with Japan, and Kim reportedly responded that he wanted to promote dialogue with Tokyo.

It was not clear if Kim mentioned a specific date or agenda topics for such a meeting with Abe.

North Korea has repeatedly declared that the abduction issue has been resolved, but Kim did not express such a belief during his summit with Trump, the source said.

Pyongyang has admitted to abducting Japanese nationals in the 1970s and 1980s, and it allowed five to return home in 2002. North Korea said others listed as abductees by Japan either died or never entered the country, a claim that Tokyo has rejected.

According to several sources knowledgeable about North Korean affairs, North Korean officials are pushing ahead with preparations for an Abe-Kim meeting, which could be held next month at the earliest.

Another possible meeting venue would be the Eastern Economic Forum hosted by the Russian government and scheduled for Vladivostok, Russia, from Sept. 11 to 13.

Russian President Vladimir Putin has invited Kim for a state visit to Russia in conjunction with the Vladivostok forum. An Abe-Kim meeting could be held on the sidelines of that forum.
