This book analyses the main factors influencing the political economy of Africa’s asymmetrical regionalism, focusing on regional and sub-regional trade, investment, movement of people, goods and services. It pays particular attention to the way in which regional and sub-regional dynamics are impacted by extra-regional relations, such with the EU, US, China and India. Because African regionalism is influenced not only by economic processes, peace and security are also analysed as important factors shaping both regional and sub-regional relations and dynamics.
