Semi-periphery.

Explanation:

The world systems theory, is a socioeconomic theory developed by sociologist Immanuel Wallerstein, which suggest that based on history and social change, there exist an economic system in which some countries benefit while others are exploited.

The world systems theory is dependent on a three-level hierarchy consisting of core, periphery, and semi-periphery areas.

The core countries dominating countries, such as USA, England, France, Germany etc., and whereby they exploit the peripheral countries for labor and raw materials.

The peripheral countries on the other hand, are dependent on core countries for capital. This includes, countries like Benin Republic, Rwanda, Burkina Faso, Mali etc.

While the semi-peripheral countries are often characterized by attributes of both core and peripheral countries. For example, Nigeria, Brazil, Argentina, Poland etc.
