The emphasis on BRIC countries as a target for expanding e-commerce businesses has waned a bit as Brazil and Russia experience hiccups in their broader economies and even China is showing some weakness in growth. Retail e-commerce still will fly high in these regions, however, according to a report from German market research firm yStats. Through 2019, the report said, B2C e-commerce sales will grow faster in Brazil, Russia, India and China than in more advanced e-commerce markets including the U.S., U.K. and Germany.
