i don't think they trust anybody in their group but they were mixing all their assets afaik but not sure who will hold their assets and they come up with the currency BRICS as well.
Let us all be honest these countries will do anything to save themselves even if it meant they have to make it look like they have a partnership or just a good relationship with other countries. They are all in agreement because there is something they need from each other. The moment there is none, I am sure they will have no hesitation to turn their backs on one another.
however i don't think they are interested in new world order, they just want to be independent in finance and economics since most of these countries were sanctioned by US and if they can work around on their own means they are free from US sanctions.
Freedom from US is equivalent of being able to dethrone the US government and the US dollar.
it's not like US doesn't have a chance to rise again. they have all the means from the start. they were just not believing from the beginning that BRICS is dedollarising and all they saw was that it's not true and that BRICS is delusional.
they are going to keep adding more countries to their side if nothing is changed in the policies. my country is allied with the US to this day, seems nothing has been done to improve our lives. maybe going with BRICS for a change will result in something better. maybe this is what those new BRICS members are thinking as well.
