If Russia had some kind of agreements with the US and other countries of the world to use the USD, those agreements were destroyed by the US and the other countries when they did the sanctions against Russia.
Of course, we are seeing that the sanctions failed, and actually became things of great benefit for Russia. But since Russia is not allowed to use the USD, and since the contracts for using it are broken, there is no money laundering involved in whatever ways they use whatever money.
What? Do you expect Russia to simply roll over and die? Are you asking their people to all commit suicide? They are free... to themselves. And they are using their freedom to build a prosperous world for themselves. If other countries want to destroy themselves by attempting to take away Russian freedom, that's up to them.
