There is no need to advise China to do something internationally, as its already in that direction in search of world market, which is saturated and needs a re division and for that a forceful entry is needed.
As far as BRICS is concerned, its not a cohesive body, though Russia is more inclined to it due Crimea crisis and its exclusion from G-20! Brazil on its parts is sore with US’s criminal spying through NSA and had proposed independent cable for data transfer for BRICS partners. India, though supported Russia on Crimea, probably due its history of similarity on Sikkim, but is pro US than China or Russia!
So, China’s imperialism has taken off and may use BRICS as one of its platform to plunder worlds’ natural wealth and market. Other countries may be benefitted partially due evolving bipolarity again but exploitation of people is going to be severe!!
