There are some, and well know by the West in other to appease some EU region that cannot easily accommodate for the sanctions. Do you really, really, think is would it, in any shape or form, even noticeably by Moscow? Their economy is much faster growing with respect the EU and far more diversified in customers than 4 yrs ago (they need now to do it also in types of exported goods). Fr sure, Russia would like to normalize relations with the West, but if you give Moscow the choice of 5Billions trade in the West for the cost of 1Billion from Asia, he will chose to maintain the Asian one without any further thought.
