Russia and the US have agreed to hold a summit between President Vladimir Putin and President Donald Trump.
Kremlin foreign policy aide Yuri Ushakov said the summit would take place in a mutually-convenient third country and that several more weeks were needed for preparations.
He said Moscow and Washington would announce the time and place of the summit on Thursday.
President Donald Trump canceled his historic nuclear summit with Kim Jong Un on Thursday, accusing North Korea of "tremendous anger and open hostility."
The meeting, which would have marked the first face-to-face encounter between a sitting U.S. president and a North Korean leader, was set for June 12 in Singapore.
Kim Jong-un is set to become the first North Korean leader to cross into South Korean territory since the end of the Korean War in 1953, as final details are put in place for the summit.
South Korea said President Moon Jae-in would personally meet Mr Kim at the border at 09:30 (00:30 GMT) on Friday.
The historic summit will focus on the North's recent indications it could be willing to give up its nuclear weapons.
Talks are also proposed between Mr Kim and US President Trump by early June.
