Thank you for the interest and informative information.
BRICS has many aims and it’s sole purpose is not to create a currency to replace the exchange of the US dollar. This may happen sometime in the distant future.
To achieve this aim which l believe has been exaggerated by the media is faced with many geographical obstacles. For instance the China / India relationship.
Economically the US is still by far the biggest strongest economy out pacing Chinas shrinking economy.
I hope Brics becomes successful in improving peace and relationships between its members and enriches the lives of its people which have been overall ignored by their governments.
The overwhelming stat is the fact that the aclumative actual GDP of the G7not PPP is 64% larger than Brics.
