The USA shot itself in the foot when it started sanctioning countries and using its monetary reserve status as a tool to impose it's political will. The fact that it's currency could be used in such a way by denying the financial system to those who were deemed to have been out of order means that all countries were vulnerable to reprisals.
The natural result is that many countries would like to dedollarise and create an alternative system which gives them some independence from potential financial bullying. In many aspects it looks as if the sanctioning of countries is an extension of its military propensity.
A serious miscalculation by the USA and very short sighted.
