The periphery, from the Greek peri-, around and phero, carry, drive, carry, it is what is on and off a central point, is this central point a geographical location, economic situation, cultural or any other. The semiperiferia, although it is not word SAR, would be what is between the periphery and the Centre. Semiperipheral countries, economic and geopolitical, generally speaking are countries developing, which are in an intermediate situation as regards underd countries and developed ones. The relations between these countries, in particular the economic and welfare, often based on little ethical criteria. Suffice it to consider the underdeveloped to provide to the developed cheap raw materials, these elaborate and returned them expensive.
