Stephen D. Krasner defined International Regimes as“Implicit or explicit principles, norms, rules and decision-making procedures around which actors’ expectations converge in a given area of international relations”in the journal International Organization in 1982. Regimes "are more specialized arrangements that pertain to well-defined activities, resources, or geographical areas and often involve only some subset of the members of international society", according to Oran R. Young, in his 1989 book International Cooperation : Building Regimes for Natural Resources and the Environment.
