Important elements of international law include sovereignty, recognition (which allows a country to honour the claims of another), consent (which allows for modifications in international agreements to fit the customs of a country), freedom of the high seas, self-defense (which ensures that measures may be taken against illegal acts committed against a sovereign country), freedom of commerce, and protection of nationals abroad.

International law is a set of rules and principles governing the relations and conduct of sovereign states with each other, as well as with international organizations and individuals. Issues that fall under international law include trade, human rights, diplomacy, environmental preservation, and war crimes.

International laws refer to a body of rules, treaties, and agreements that unite countries. Nations collaborate to establish legally binding policies that they believe would benefit their citizens. It is an independent legal system that functions independently of the legal system of a particular state.
