An emerging market is a country that has some characteristics of a developed market, but does not meet standards to be a developed market. This includes countries that may become developed markets in the future or were in the past. The term "frontier market" is used for developing countries with slower economies than "emerging". The economies of China and India are considered to be the largest. The four largest emerging and developing economies by either nominal or PPP-adjusted GDP are the BRIC countries (Brazil, Russia, India and China). The next five largest markets are South Korea, Mexico, Indonesia, Turkey, and Saudi Arabia. Iran is also considered an emerging market.
