The absence of a common border between Russia and Armenia complicates the integration process, the head of the Caucasus Institute, Alexander Iskanderyan, told VK correspondent.
Asked about the prospects for the Eurasian Union project in the South Caucasus, Iskanderyan said that such prospects do not seem promising to him.
"Speaking about integration with Georgia, such a possibility simply doesn't exist, even in the future," the expert said.
Azerbaijan is a very rich nation, having great oil resources, so it's very cautious in such matters, Iskanderyan believes.
He also said that Armenia is interested in further cooperation with Russia, but the integration process is complicated by the absence of a common border.
