International economic law is a field of international law that governs the regulation and conduct of states and international organizations. This field encompasses public international law, private international law, and domestic law relevant to international business transactions.

This field sets the framework for international business operations, evolving over the years. The interdisciplinary nature of international economic law means that changes in one area impact others. Alterations in financial regulation affect international trade flows, and shifts in environmental law can influence investment policies.

The scope of international economic law is vast, including laws such as international trade law, financial regulation, labor and services law, and environmental law.

Issues like digital trade, climate change, and global inequality require new legal frameworks from the international economic law.

The foundational principles of international economic law are traced to economic theories, such as those proposed by Adam Smith in his work The Wealth of Nations and Karl Marx's critique of political economy in Das Kapital.

Environmental law intersects with economic activities, addressing issues like climate change and environmental protection in trade agreements.

The relationship between human rights and international economic law is an area of focus. Issues such as labor rights and access to essential services on human rights are central to contemporary discussions in the field.
