The GATS aims to ensure that the laws and regulations applied by WTO member governments to trade in services are transparent and fair. Its most important element for market opening is the schedule of specific commitments that each signatory has attached to the GATS as an integral part of the agreement. In these timetables, resulting from the Uruguay Round negotiations, the signatories indicated the extent to which they would grant full market access and, indeed, in certain services sectors. GATS obligations apply to “measures taken by Members affecting trade in services” (Article I of the GATS). The actions of members are actions taken by central, regional and local authorities and by non-governmental bodies in the exercise of the powers conferred by central, regional or local governments or authorities. .
