(a) stricter national measures concerning the conditions for trading, hosting, holding or transporting specimens of species in Appendix I, II and III, or a total ban on them; The aim is to ensure that the international trade in wildlife specimens does not endanger the survival of the wild species and provides different levels of protection to more than 35,000 species of flora and fauna. To ensure that the General Agreement on Tariffs and Trade (GATT) was not violated, the GATT secretariat was consulted during the development process.  The Convention on International Trade in Endangered Species of Wild Fauna and Flora, often referred to as CITES (SIGH-teez), is an agreement between governments that regulates the international trade in wildlife and wildlife products, from live animals and plants to food, leather goods and jewellery. It came into force in 1975 to ensure that international trade does not jeopardize the survival of plants and wildlife. For many years, CITES, which currently has 183 parties, has been part of the conservation agreements with the largest number of members. CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) is an international agreement between governments. The aim is to ensure that international trade in wildlife specimens does not jeopardize their survival. 3. The provisions of this Convention do not in any way affect the provisions or obligations arising from international treaties or agreements between States that enter into an EU trade agreement or regional agreement for the establishment or maintenance of joint external customs control and the abrogation of customs control between the parties to or arising from these obligations.
6. Any reference to the « Party » covered by Article 1 of this Convention under Article 1 of this Convention is interpreted to refer to any regional economic integration organization charged with negotiating, concluding and implementing international agreements in the matters covered by this Convention. (b) national measures to restrict or prohibit the trade, reception, possession or transport of species not included in Appendix I, II or III. CITES is one of the largest and oldest agreements for conservation and sustainable use. Participation is voluntary and countries that have agreed to be bound by the convention are called contracting parties. Although CITES is legally binding on contracting parties, it is not a substitute for national laws. On the contrary, it provides a framework respected by each party, which must adopt its own national legislation for the implementation of CITES at the national level. Often, there is no national legislation (particularly in parties that have not ratified it) or sanctions with the seriousness of the crime and insufficient deterrence for wildlife traffickers.  In 2002, 50% of the contracting parties missed one or more of the four main requirements for one party: the designation of administrative and scientific authorities; laws prohibiting trade in violation of CITES; Sanctions for trade; Laws that provide for the seizure of designs.  National laws transposing CITES are essential to ensure that trade in protected species is legal, sustainable and traceable.
Legislation authorizes government officials to act, regulates human behaviour and articulates wildlife conservation and trade policy. It is the most well-known conservation convention in the world. It is a comprehensive agreement between governments to regulate or ban international trade in endangered species.
