"It's of course pretty possible to suggest that in one way or another this topic will be touched upon. It is impossible to expect an immediate and serious progress because this issue is extremely sensitive and will require meticulous, continuous, and what's important, constant work on the expert level," Peskov told journalists.
He noted, however, that the upcoming meeting between the two leaders would help in solving the issue soon.
"We hope that Friday's contacts with Prime Minister Abe will basically help in forming a working and constructive atmosphere in bilateral relations, that in turn will make it possible to develop and continue forward in this expert work," Peskov added.
