Russia is in for a harsh wakeup when the Ukrainian war ends (or in 2026 if the war is still ongoing IMO). Their economy is “looking good” right now only because it has been switched to a war economy, and the Kremlin injects tons of cash in it, but lots of it isn’t useful for the russians, it’s just getting destroyed in the war.
Also the ruble is close to a dead currency, nobody wants to trade in it any more.
