The present state of international economic law leaves much to be desired. Anchored by the multilateral General Agreement on Tariffs and Trade, which led to the creation of the World Trade Organization, and complemented by a vast network of bilateral and multilateral investment treaties and free trade agreements, international economic law is drawn from diffuse sources. Additionally, the WTO Dispute Settlement Body and Appellate Body, which interpret the GATT provisions, and arbitral tribunals, which interpret investment protection agreement provisions, shape the content of international economic law. However, the patchwork of treaty text and dispute settlement rulings into a body of law is unraveling.
