The difference is that, the money is usually in the west, and they are producing a lot more of what people want. Russia and China only makes money based on what the west gives them, west (nations that use swift mainly) do not really require any money from Russia or China, they need "things" from them.
In a case where west finds better energy sources, good alternatives and wheat stocks, they do not need Russia at all, which can be done with clean energy, solar panels, nuclear plants, wind turbines and so forth which would take time but can be done.
Same goes for china, they manufacture things and that is how they make money, move those factories you have to another nation, and china would become poor all over again. All in all, west doesn't need the money these nations have, they need to use them for their resources, and if those nations start to work with another system, west will simply not work with them which would hurt east a lot more.
Well, the West are doing a piss poor effort to replace China as a mass supplier of computer chips.
The Chinese efficiency and their discipline and their ability to mass produce electronic components are not equaled by any other country.
So let's give credit ..where credit is due. The Oil and Gas that Russia are supplying ... cannot be replaced within the next 5 years, so Europe is going to rely on Russia for at least the next 5 years... and the alternative energy and other sources of Gas are going to be very expensive to replace.
