Don't be so Europe-centered. Almost no country in Asia and Africa for example, have implemented sanctions against Russia. China and India alone have almost 3 billion inhabitants. That is five times as much as entire Europe and three times of all Western countries together. Both China and India have not turned against Russia and continue to trade diligently with the country.
Moreover, Europe continues to buy oil and gas, in part undermining its own sanctions. This can be seen in the value of the ruble alone, which has significantly improved again and is almost at pre-war levels.
Its sanctions affect the Russian economy but obviously not significantly, it is Europe who is having worse days in Russia. Europe depends largely on Russian gas, but Russia is not dependent on Europe. In addition to legalizing cryptocurrencies to avoid sanctions, Russia still has its supporters. China and India are ready to buy gas from Russia if the EU refuses, the two most populous countries in the world, so energy consumption will not be inferior to the EU.
I agree that if we look at the trade aspect, we cannot focus entirely on Europe. However, in other aspects, such as tourism, culture, education, Europe is perceived by post-soviet countries as a model and reference point. In russia, most people know about European cultural and artistic heritage, not about Indian or African, for example. The situation is the same with tourism. Therefore, the closure of European borders for russia is perceived more painfully and noticeably, even though trade with many other countries, unfortunately, continues.
