Russian Railway concessions are very convenient for Armenia: Kopyrkin, the Russian ambassador, said that he attended a meeting of the head of Russian Railways with Nikolay Pashinyan, and he was impressed by the analysis of the work of the concessions, including its efficiency compared to the railways of other countries in the region and beyond. The concession agreement itself continued under very favorable, perhaps even incredibly favorable conditions for the Armenian side. In terms of the efficiency of concessions compared to other railways in the region, and not only in the region, he really amazed me, the ambassador said in an interview with public radio. Within three months, the joint work committee must find answers to the questions of interest to the Armenian side, including in the field of transportation and logistics. @SputnikARM.
