3.What is international law?

International law deals with the relationships between states, or between persons or entities in different states. It sub-divides into "public international law", and "private international law". When used without an adjective, "international law" generally refers to "public international law", and this article concentrates on that meaning.

Traditionally, international law had states as its sole subjects. With the proliferation over the last century of international organizations, they have been recognized as its subjects as well. More recent developments in international human rights law, international humanitarian law and international trade law (e.g. NAFTA Chapter 11 actions) have led to individuals and corporations being increasingly seen as subjects of international law as well, something which goes against the traditional legal orthodoxy. Since international law increasingly governs much more than merely relations between sovereign states, it may be better defined as law decided and enforced at the international, as opposed to national level. See world government for trends and movements leading in this direction.
