Establishing new economic partnerships is never a bad idea. Joining BRICS does not mean severing relations with the United States and Europe, or even challenging them.
Agree because we see even inside NATO, Turkey did not choose side between the USA., NATO, Russia and Ukraine. They have trades with all those nations and they are still in NATO.
The United Arab Emirates found itself for the first time in an alliance with its neighbor Iran, despite the dispute between them, as well as the Kingdom of Saudi Arabia.
UAE have trades with many big nations that try to make their influence on UAE but it is not easy because UAE knows that they can work with all and should not make any harmful decision for their future relationships and trade chances with any big nation. Like after the Russia-Ukraine war, the USA, China and Russia all had some conversations in the UAE.
In fact, we do not know what criteria were agreed upon to choose to invite any of the countries, except that the process was in the form of suggestions from the first members, and not based on requests to join.
I also believe that BRICS has become a media phenomenon that is given more than its value in assessing its capabilities in reality.
A first criterion is not be a member of NATO because BRICS is created and expanded to build up a multipolar world and to compete with NATO. Other criteria, to be honest, I don't know but likely they are prioritizing nations with big economy sizes.
