Transitioning to Emerging Market Status?

From the IMF's Regional Economic Outlook for Sub-Saharan Africa,2008(PDF):

The term “emerging market” was coined in 1980 to refer to countries that had stock markets and were in transition toward having the features of the mature stock markets in industrial countries.This box suggests that some African countries fit within the emerging market group and supports this view by benchmarking these African economies of 2007 against the ASEAN countries (Indonesia, Malaysia, Philippines, Singapore,and Thailand) of 1980, when the term “emerging market” entered the lexicon.
Selected African countries compare favorably with the ASEAN countries of 1980. The ASEAN countries were already experiencing strong economic growth. Yet, in many other respects, the ASEAN countries looked quite different from what we see today. Inflation rates were still high in some cases, the depth of their financial sectors was limited, foreign direct investment had yet to accelerate, and their financial
resources, reflected in international reserves, were adequate but not high. Many African countries have perhaps reached broader macroeconomic stability than the 1980 ASEAN benchmark. Growth is strong, inflation moderate, and international reserves relatively high. Like ASEAN, financial depth remains limited.Foreign direct investment is quite high, although this is in large part a reflection of the larger share of naturalresources such as oil in the case of African countries.2 Debt-to-GDP ratios are low.
