U.N. chief Ban Ki-moon will visit North Korea, the first time the head of the international body will visit the reclusive state in over two decades, South Korea's Yonhap news agency reported.

The Secretary-General plans to travel to Pyongyang later this week and will meet with the country's leader Kim Jong Un, to discuss North Korea's nuclear weapons program and other Korean peninsula matters, Yonhap said on Monday, citing a "high-level U.N. source."

"There can't be such a situation where the U.N. Secretary-General visits North Korea and does not meet with the supreme leader of the U.N. member state," the source said.

Ban's office declined to confirm the trip.

"We've seen the reports, but aren't commenting on this for now. Will let you know if that changes," Eri Kaneko, Ban's spokesperson told CNN.

His office added: "The Secretary-General has always said that he is ready to play any role in order to help enhance dialogue, stability and peace on the Korean peninsula."

Meanwhile, South Korea's Unification Ministry told CNN, "We've seen the reports. We're currently looking into the matter."
