"The concept of “like services and service suppliers” used in the General Agreement on Trade in Services (GATS) is still very much uncharted territory.....This contribution focuses on the concept of “likeness” in the context of the national treatment obligation (Article XVII of the GATS). It discusses the possible implications of the combined reference to “like services and service suppliers”, as well as the relevance and role of the modes of supply in determining 'likeness'."
