He noted that currently the OSCE monitors are operating on the Russian side only on two crossing points - "Donetsk" and "Gukovo."
Ukraine considers that presence of observers on just two points is not effective.
"Ukraine continues to insist on expanding the presence of the OSCE over the entire section of the Ukrainian-Russian border ... Ukraine's proposals were brought to the attention of the OSCE participating States on Oct. 17 and presented during the negotiations in Milan," he said.
Perebyinis added that on Oct. 22 the OSCE Permanent Council will consider the continuation of the mission's mandate (which expires on Oct. 24), as well as the matter of its expansion.
"Unfortunately, only Russia's position on this issue remains negative," he added.
Speaker of the Ministry of Foreign Affairs also said that if Russia blocks such decision, it will be responsible for the failure of this paragraph of the Minsk agreements.
