Jim O'Neill expressed surprise when South Africa joined BRIC since South Africa's economy is a quarter of the size of Russia's (the least economically powerful BRIC nation). He believed that the potential was there but did not anticipate inclusion of South Africa at this stage. Martyn Davies, a South African emerging markets expert, argued that the decision to invite South Africa made little commercial sense but was politically astute given China's attempts to establish a foothold in Africa. Further, South Africa's inclusion in BRICS may translate to greater South African support for China in global fora. He has great belief that the "S" in "BRICS" could be replaced eventually by SADC.
