China is creating a cryptocurrency to eliminate the mediation of US dollars. This currency will transact in China, they will scale up payments globally.
I don't think China's monetary revolution will be successful because Huawei out of the 100 largest companies in the world has only 96. Hundreds of US companies have greater influence and much higher liquidity with the influence of a company from China.
China yuan will slowly shift the dollar currency. It has been projected because the USA has been standing tall with their currency economically for too long and USA companies are indeed quite superior, but we will see in a few years whether the dominance of the dollar will be displaced, everything can happen anytime and it will. affect trade and economy because of the high competitiveness between China and USA I believe that the dollar will someday collapse.
