China and Russia have been trying to avoid USD for years and now,i think that they have succeeded by getting crude oil from Iran with their own currencies.Tgey are even trying to add some more countries in their group in the war against USD.
Just like the ICO I joined where they are not accepting US citizen. Russian countries as well as China are trying to avoid dealing business with USD currency because of the conflict with the monetary aspects in each country. Right now Russia and China are on the right track on their motives to avoid the usage of USD.
