The General Agreement on Trade in Services was created to extend the multilateral trading system to the services sector, just as the General Agreement on Tariffs and Trade (GATT) provided for such a system for trade in goods. The agreement came into force in January 1995. This was the largest negotiating mandate ever agreed: discussions aimed to extend the trading system to several new areas, including trade in services and intellectual property, and to reform trade in sensitive sectors of agriculture and the textile industry; all the original GATT articles were discussed [30] The final act relating to the conclusion of the Uruguay Round and the formal introduction of the WTO regime was signed on 15 April 1994 at the ministerial meeting in Marrakech(Morocco) and is therefore known as the Marrakesh Agreement. [31] Another group of agreements not included in the diagram is also important: the two multilateral agreements that have not been signed by all members: civil aircraft and public procurement. A country wishing to join the WTO submits a request to the General Council and must describe all aspects of its trade and economic policy that affect WTO agreements. [95] The application is submitted to the WTO as part of a memorandum reviewed by a working group open to all interested WTO members. [96] This dispute resolution, based on agreements and obligations, and trade policy reviews, are supported by an exercise in transparency. The agreement on the application of health and plant health measures, also known as the sPS agreement, was negotiated during the Uruguay round of THE GATT and came into force with the creation of the WTO in early 1995. Under the SPS agreement, the WTO sets limits on members` policy on food safety (bacterial contaminants, pesticides, inspection and labelling) and animal and plant health (imported pests and diseases). WTO agreements deal with goods, services and intellectual property. They set out the principles of liberalisation and the exceptions allowed. These include commitments made by some countries on tariff reductions and other trade barriers, as well as opening up and opening up services markets.
