The term "Semi-Periphery" refers to countries that are in between the core and periphery in the global economic system. These nations often have a mix of both developed and developing characteristics, playing a crucial role in international trade and economics. They can influence global markets while also facing challenges typical of less developed countries. Semi-peripheral countries often serve as a buffer between the wealthy core countries and the less developed peripheral countries. Examples include nations like Brazil, India, and South Africa, which have growing economies and increasing political influence, yet still experience issues such as inequality and underdevelopment.
