You are right in this observation because I also noticed that the coming of Donald Trump seems to have made them forget about that project. I'm not surprised though because I don't expect country like China to be talking about BRICS when they are at the verge of losing their biggest market being the US due to tariff hike. This tariff war seems to have more effect and even immediate effect than anything else, hence the reason their are piping low on that BRICS arrangements. What I also notice is that most of the members are working out their private relationship with the US and are not working together as a block.
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.
There is something I know for sure which is that as long as China is a member of the BRICS countries, they cannot continue in such a project in a time of a president like Trump who will not spare any effort to destabilise them. China is a country that is more interested in the money and business than anything so they will not go against America at least for now because the US is very important to them in terms of business.
Assuming the BRICS countries could stick together at this point, they would have been able to bend president Trump a little but China and India will not allow them think in that direction because both of them have a lot to lose if the US cut ties with them.
