Sanctions imposed on Russia as a result of its activities (whatever the truth may be about them) are not causing Russia any damage, as far as I can see, but the response by Russia is causing damage to the EU, particularly farmers in Poland, Greece and Italy. Even a cheese maker in England has been adversely affected.
In Russia there is talk of Russian sanctions being applied to alcohol, cigarettes and carbonated soft drinks from the EU and the USA. This will cause damage to the Western economies of the nations that produce whiskey, wines and colas, but, if imposed, may well assist in improving the health of the Russian people.
It strikes me that you should not pick a fight that you cannot win.
