Putin and his, erm, colleagues constantly use “multi-polar world” and “prevention of (implied US-American) hegemony” as a reason for their actions. This includes the desire to make Russian Rouble one of the world's currencies.
If anyone, I am extremely tired of US-Americans blaming their poor policies on “The Russians”, but in this case, the possibility of US Dollar losing some of its value does indeed align with the Kremlin's wants.
