Protectorate
Foreign relations
In practice, a protectorate often has direct foreign relations only with the protector state, and transfers the management of all its more important international affairs to the latter. Similarly, the protectorate rarely takes military action on its own but relies on the protector for its defence. This is distinct from annexation, in that the protector has no formal power to control the internal affairs of the protectorate.
Foreign relations
Protectorates differ from League of Nations mandates and their successors, United Nations trust territories, whose administration is supervised, in varying degrees, by the international community. A protectorate formally enters into the protection through a bilateral agreement with the protector, while international mandates are stewarded by the world community-representing body, with or without a de facto administering power.
Protected state
A protected state has a form of protection where it continues to retain an "international personality" and enjoys an agreed amount of independence in conducting its foreign policy.
