The General Agreement on Trade in Services (GATS) created a framework for international trade rules in services. GATS aims to promote services trade liberalization on a mutually advantageous basis. It covers four modes of supplying services: cross-border trade, consumption abroad, commercial presence, and presence of natural persons. Under GATS, countries schedule specific commitments to liberalize certain services sectors and modes of supply, while maintaining exceptions. Commitments are bound under the GATS framework and principles of most-favored nation treatment and transparency.
