International law operates as a body of rules having binding character on the nation states. As such, it limits the power of nation.
3. International Morality:
A set of norms valued by the international society also acts as limitation of power. Even though they are neither codified, nor binding, they enjoy great sanctity. Certain values like peace, equality, mutual respect etc. remain core element of international relations.

Agency like U.N. remains a check on growing preponderance of power. Through its activities it checks and balances power of nations in the international relations.
5. World Public Opinion:
This aspect has acquired prominence in recent times like the anti-Vietnam war protests and peace movements have revealed what people can do in international relations. States can no longer remain aloof from the public opinion.
