Least Influential member of BRICS?

Grouping India and (especially) Brazil with China and Russia is hilarious enough, but South Africa being added into the mix is basically geopolitical sh-tposting.

My guess the rationale was "it would look nice if we had somebody from Africa", since there are quite a few much stronger emerging economies than South Africa.

So maybe BRICK with K for Kenya to keep the acronym similar?  But yeah, this was always a grouping centered around having cool acronym more than anything else.
