Yes, that's true, for now BRICS members are busy with their respective national affairs, especially after Trump took the policy of raising tariffs, they seem to forget the projects they established in the BRICS provisions that they have made so far, for now they are focusing on their own countries, because that is much more important, it's just that they are postponing it for some time in the future, I think it's like that waiting for the trade tariff war to subside.
Waiting for tariff war to subside will be tough, because I think the current tariff being imposed is to prevent de-dollarization in the first place.
So, I kinda expect current tariff to be long lasting except if a nation can negotiate with the US to reduce their tariff which many countries are doing right now.
I guess dollar gonna still dominate for next few decades.
