In parallel to the process of globalisation, competition law and policy have been gaining a more international nature. Within this framework, international cooperation in this area has an increasing importance. International cooperation is achieved on multilateral and bilateral platforms. Basically, international cooperation allows the exchange of information and experience between states on one hand, and creates some limited opportunities for the implementation of competition rules on the other.

Turkish Competition Authority has a critical role in the competition policy chapter, which is an important chapter in the EU full membership process. In addition to the EU process, Turkish Competition Authority has been actively participating in the studies conducted by multilateral platforms such as OECD, UNCTAD, International Competition Network (ICN) and World Trade Organization (WTO). 
Within the framework of bilateral relationships, Turkish Competition Authority has signed Memorandum of Understandings with the competition agencies of other countries such as Korea, Portugal, Bosnia and Herzegovina, Mongolia, Russian Federation, Turkish Republic of Northern Cyprus, Kazakhstan and Peru.

In cooperation with the Statistical, Economic and Social Research and Training Centre for Islamic Countries (SESRIC), operating under the Organisation of Islamic Cooperation, the Competition Authority provides technical assistance for the training of the competition agency personnel from Islamic countries which have recently adopted competition legislation. 

Turkish Competition Authority has been sharing its know-how and experience through the appropriate platforms in order to support the capacity building efforts of the countries located in the same region as Türkiye.
