In accordance with Article XXI, specific obligations may be amended subject to certain procedures. Countries likely to be affected by such changes may invite the changing member to negotiate compensatory adjustments; these must be conceded on the basis of the MFN. The prosperity of the global economy over the past half century is due in large part to the growth of world trade, partly due to far-sighted officials who created the GATT. They have defined a number of procedures aimed at providing stability to the trading environment and thus facilitating the rapid growth of world trade. In the long term, GATT conference countries have helped to put the global economy on a solid footing and thus improve the livelihoods of hundreds of millions of people around the world. The commitments contained in the GATS can be divided into two broad groups: general commitments that apply to all members and service sectors and commitments that apply only to sectors in a member`s commitment plan. These obligations are defined in individual timetables, the scope of which can vary considerably from one Member State to another. The relevant terms and concepts are similar, but not necessarily identical to those of the GATT; Domestic processing is, for example, a general obligation in trade in goods and non-negotiable as in the GATS. Another was the internal crisis of 1965, which ended with the Luxembourg compromise. Preparations for the new round were immediately overshadowed by the chicken war, an early sign of the impact of variable levies under the Common Agricultural Policy.
Some participants had expressed concern that the convening of UNCTAD, scheduled for 1964, would lead to further complications, but its impact on the negotiations themselves was minimal. Following the UK`s vote to leave the European Union, proponents of leaving the European Union proposed that Article 24, paragraph 5B of the treaty could be used to maintain a “stalemate” in trade conditions between the UK and the EU if the UK left the EU without a trade deal, thereby preventing the imposition of tariffs. Proponents of this approach believe that it could be used to implement an interim agreement until a final agreement of up to ten years is negotiated.  Transparency: GATS members are required, among other things, to publish all measures of general application and to set up national investigative bodies to respond to requests for information from other members.
