It is pretty much low cost making your economical data available.
Most of the "things" needed is the good will of the respective government.
Accountability is the name of the game and that is what most people are not willing to conceive.
I read some articles about BRICS and generally they say to increase economic growth and build cooperation between members who join it and if you look at the purpose of establishing BRICS it is good but we talk about growth after that happens because maybe if the intention is only to accommodate the dominance of the dollar I think it will be difficult. Especially for my country, it is often heard that the benefits of joining BRICS can strengthen the exchange rate but to what extent that continues I am unable to analyze.
The concept of accountability is like only listening to opinions from the results of decisions and if it is associated with the process of developing Accountability I do not think that is the right strategy. Where a country has a view to economic growth and that can be achieved through the power of growth and positioning itself is a strategic step when the country has good financial strength.
