Turkey, a party to the 1947 General Agreement on Tariffs and Trade (GATT) and a member of the World Trade Organization (WTO) since 1995, implements free trade agreements in accordance with Article XXIV of the 1947 GATT. Under this article, Turkey could give its trading partners more favourable treatment within the framework of a customs union or free trade area, without extending this treatment to all WTO members, subject to certain conditions. The agreement contains provisions for trade remedies (Articles 2.17 to 2.19), i.e. subsidies and countervailing measures, anti-dumping and global safeguard measures on the basis of relevant WTO agreements. The provisions on the protection of intellectual property rights (Chapter 4 and Appendix XX) include trademarks, copyrights, patents and geographical indications and include provisions relating to respect for intellectual property rights and cooperation between the parties. They are based on the WTO agreement on trade-related aspects of intellectual property rights (TRIPS) and provide a high level of protection, taking into account the principles of the most favoured nation and national treatment. Without prejudice to WTO provisions, the Turkey-EU customs union provides an important legal basis for Turkey`s free trade agreements. Within the framework of the customs union, Turkey is directing its trade policy towards the EU`s common trade policy. This harmonization concerns both autonomous regimes and preferential agreements with third countries. In December 2016, the European Commission published an assessment proposing to update and modernise the agreement, which includes services and public procurement.  The report ends with two options; Improved trade framework (ECF) or comprehensive free trade agreement (ACFTA).  Starting in 2020, the Council has not yet adapted the proposal. Since 2015, the Turkish government has held several meetings to assess the update of the agreement.
 In the context of the pan-European accumulation, it may be necessary to determine the original character of products that are in common practice in the customs union but which are exported or used in the manufacture of products for export to other countries under the pan-European accumulation system. To this end, Decision 1/1999 of the CE-Turkey Customs Cooperation Committee of 28 May 1999 (OJ L 199 of 20.12.1999) 204, 04.08.1999, p. 43), a «supplier statement» submitted to the exporter and used by the exporter as evidence of origin under preferential agreements with other countries under the pan-European coordination system. The parties recognize that economic development, social development and environmental protection are interdependent. In Chapter 7, they reaffirm their commitment to multilateral contracts and principles in the environment and work and commit to a level of protection by recognizing the right of each party to set its own level of environmental and labour protection. Arbitration procedures do not apply to this chapter. In today`s world, countries tend to enter into bilateral and regional free trade agreements, as the World Trade Organization (WTO) has achieved a high level of liberalization, with insufficient WTO rules under current conditions and an inefficient multilateral trading system to allow better market access.
