Dear Sir
I do know that some of the Russian states bordering China can benefit from CPEC but its impact will be limited and economically may or not be viable depending on the nature of product. What I see is, CPEC ends near Urumqi, if some Russian find it interesting to import from Urumqi, its fine but it may little to do with Pakistan unless Pakistan takes Russiaj contracts and delivers to Russia through Urumqi and utilise Chinese extensivr network to reach in Russia
The point i was making is, Moscow is near Europe. Most of Russia already has abundance of natural resources so their bilateral trade with this region is limited that they can use to gain benefit from CPEC
