What is it about?
International Economic Law (IEL) is an area of public international law that governs cross-border economic relations involving states, individuals, and international entities. It is a multidisciplinary field encompassing international trade, monetary, and investment law, alongside emerging areas such as intellectual property, environmental standards, and human rights. IEL’s foundations lie in treaties, customary law, general principles, and the jurisprudence of international tribunals. Major institutions include the World Trade Organization (WTO), the World Bank, and the International Monetary Fund (IMF), each contributing to global economic stability through legal frameworks and dispute resolution. In the realm of international trade law, the WTO’s legal instruments have been central to promoting non-discriminatory trade practices. The WTO’s Dispute Settlement Mechanism has further reinforced the rule-based trading system. International investment law, characterized by a proliferation of bilateral and multilateral investment treaties, seeks to protect foreign investments through provisions on fair and equitable treatment, protection against expropriation, and mechanisms for investor-state dispute settlement. Overall, IEL is increasingly shaped by regional agreements, non-state actors, and evolving global issues such as climate change, digital trade, and corporate accountability. Its continued evolution reflects the need to reconcile economic growth with legal, social, and environmental priorities in an interconnected world.

Why is it important?
International Economic Law is important because it provides the legal framework that allows countries to trade, invest, and cooperate in a stable and predictable way. By setting clear rules through institutions like the World Trade Organization, International Monetary Fund, and World Bank, it helps prevent disputes, promotes fair competition, and supports global economic stability. At the same time, it increasingly helps align economic growth with broader priorities such as environmental protection, human rights, and sustainable development in an interconnected global economy.
Perspectives
It is a privilege for me, as a lawyer and diplomat, to join other distinguished authors in contributing a chapter. This work is intended to provide a clear and accessible overview of contemporary international economic law for diplomats and other interested readers. I hope it proves useful to practitioners and those engaged in the field.
