World leaders imposed the restrictions after Crimea annexation and Donbas military invasion
The cost of Russian aggression in Ukraine has now been estimated. According to Putin's spokesman Serhiy Glazyev during the two-year period under sanctions' pressure Russia lost 250 billion US dollars. The official claims, the budget money keep on decreasing because of the international restrictions.
Two years ago the Russian Federation annexed the Crimean peninsula and later invaded Ukraine's eastern regions of Donetsk and Luhansk. Willing to deter further aggression, the E.U. along with the U.S.A., Canada, Australia, and Japan imposed economic sanctions against Moscow.
The restrictions are aimed mainly at the bank, oil, and defence industry branches. A prominent Russian edition "Vedomosti" estimated two more years under sanctions along with cheap oil can presumably result in 600 billion US dollar losses.
