Client state

A client state, in the context of international relations, is an umbrella term that broadly refers to any state economically, politically, and militarily subordinated to a more powerful controlling state. It typically describes a bilateral relationship that is mutually beneficial, characterized by different but shared obligations.

Variants of a client state are associated state, dominion, condominium, self-governing colony, neo-colony, protectorate, suzerain, puppet state, satellite state, vassal state and tributary state.
