The BRIC thesis posits that China and India will become the world's dominant suppliers of manufactured goods and services, respectively, while Brazil and Russia will become similarly dominant as suppliers of raw materials. It's important to note that the Goldman Sachs thesis isn't that these countries are a political alliance (like the European Union) or a formal trading association - but they have the potential to form a powerful economic bloc. BRIC is now also used as a more generic marketing term to refer to these four emerging economies.
Due to lower labor and production costs, many companies also cite BRIC as a source of foreign expansion opportunity.
