The Russian Ministry of Foreign Affairs permitted NATO's participation in the Eurasian security architecture.
Such a scenario is not ruled out, said Alexei Drobinin, director of the department's foreign policy planning department.
"We, as part of the participants in this architecture, do not rule out the possibility of the participation of those countries that at the current stage remain members of the North Atlantic Alliance, let's say, but in certain circumstances may think of the need for some additional steps to ensure their security," said the diplomat.
According to him, individual NATO member states can agree with Russia on personal security guarantees.
