After 1970s, a group of scientists claimed clearly the invalidity of the state-centric approaches as a result of globalization and emerging non-state actors.

Concepts such as inequality and exploitation were increasingly discussed. Paradigm debate began with the rejection of assumptions adopting the state as a basic actor.
