I believe the most solid thing about the Russian economy is the fact much of their GBP depends on the commerce of gas and oil, those are commodities which will always have intrinsic value in the Asian market, as still many countries in that continent rely on fossil fuels to keep their machines going. If Russia did not have as much energy in the form of gas and oil, they would be indeed in big trouble. And since now the European Union seems to be pushing for a transition towards green energy and the political consequences of his conflict, the Kremlin has found new potential and welcoming clients in both China and North Korea, India is also willing to buy energy from them at discount, as they have already done in the past.
