Peskov clarified that this topic was repeatedly mentioned by Putin.
"President Putin said that this is beyond the very red lines that he has repeatedly spoken about earlier," the spokesman said.
He clarified that Russia and Belarus, in response, can take actions that will ensure the strategic interests and security of the two allied states.
Earlier, Lukashenko said that the United States, under the guise of training centers, is creating NATO military bases in Ukraine.
According to him, he and Putin are holding consultations on this issue and "agreed that it is necessary to take some action."
