I think BRICS will be excellent development on the global market because it will change the economy of World. US is hurting many countries which are good countries but US want to be king in the World and it don't want any country away from that country . Many people are thinking that US will be dominant forever but there will be huge change in the technology and development but it will take time . China is big country of the world according to population and that is reason India is jealous with china because Chinese people are hard working people and they will get high economic status on the World Map.There are many countries which want to be part of BRICS system but there are many issues on International level and we are facing no progress in this concept.
That's about the way things are. As for de-dollarization, it continues all the time. According to the latest data, more than half of Russia's total foreign trade turnover is carried out in rubles, the rest in yuan, rupees and other currencies, and only about 20% in dollars. Every world currency has lived for about a hundred years. Before the dollar, it was the British pound, which was replaced by the dollar when the British Empire collapsed.
The era of the dollar began around the middle of the 20th century, which means that the dominance of the dollar will end by about 2050-2070 (if we consider the end of the Bretton Woods system in 1971 and the beginning of the dollar's existence as a net debt without reference to gold). Although this may happen earlier, since the economic and scientific development of society does not occur at a linear rate, but exponentially.
