South Africa sought BRIC membership since 2009 and the process for formal admission began as early as August 2010.  South Africa was officially admitted as a BRIC nation on December 24, 2010, after being invited by China and the other BRIC countries to join the group.  The capital "S" in BRICS stands for South Africa. President Jacob Zuma attend the BRICS summit in Sanya in April 2011 as a full member. South Africa stands at a unique position to influence African economic growth and investment. According to Jim O'Neill of Goldman Sachs who originally coined the term, Africa's combined current gross domestic product is reasonably similar to that of Brazil and Russia, and slightly above that of India.  South Africa is a "gateway" to Southern Africa and Africa in general as the most developed African country.  China is South Africa's largest trading partner, and India wants to increase commercial ties with Africa.  South Africa is also Africa's largest economy, but as number 31 in global GDP economies it is far behind its new partners.
