The United Nations has confirmed that Secretary-General Ban Ki-moon will go to Moscow to attend Victory Day events later this week.
Spokesman Stephane Dujarric told reporters on May 4 that Ban's meetings in Moscow are not yet finalized. He's attending events marking the 70th anniversary of the defeat of Nazi Germany in World War II.
North Korea has said it is sending Kim Yong Nam, the head of the presidium of the Supreme People's Assembly, to the Moscow event.
That ended speculation that supreme leader Kim Jong Un would make his international debut there.
Ban, who is South Korean, will also visit Ukraine during this trip to meet with President Petro Poroshenko.
Ukraine's foreign minister last week criticized the idea of Ban visiting Russia amid a pro-Moscow separatist rebellion in eastern Ukraine.
