This is another factor in the decline of foreign currency earnings of Russian companies. We mean real currency, not tugriks, rupees and other glass.

In general, the disadvantage of the "Sanctions do not work" religion and its followers is that they do not take into account the systematic nature of all sanctions measures. Each particular sanction can be circumvented by one or another crooked path. Any one sanction may simply not work for some internal or external reason of its own.
However, their number and systematic approach gradually lead to the result necessary for the creators of the sanctions policy. Stretching over time allows them to be adjusted and supplemented.
The goal remains the same - on the one hand, the West wants to bring Russia to the state of Iraq in the time of Saddam during the "Oil for Food" program and actually remove Russia from the list of potentially developed and developing countries. On the other hand - it should be done in such a way that the economies of developed countries adapt to Russia's withdrawal from the world economy or at least reduce their presence in it.
The point of the measures is to deprive the Kremlin of the resource, and thus the opportunity to pursue its policy. Besides, the West realizes that the Kremlin regime is bankrupt and sooner or later other people will come to power. There is a risk that those will come who will set their goal not to plunder the country, as the current ones do, but on the contrary - to revive it. For this purpose it is required to create for such people the maximum possible difficulties and to bind them by a huge number of conditions under which Russia will be let back.
