In the 2000s, Turkey began to increase its efforts to transform from a model country to a central country by implementing an active foreign policy in its geopolitical region and neighboring regions. Starting from the 2000s, Turkey defined new principles guiding its foreign policy and implemented the strategies it followed. In addition to the basic foreign policy principles of Turkey in the regional and global arena, principles such as multi-vector diplomacy, proactive foreign policy, “zero problem” with neighboring countries, transition from (...) a “model country” to a “central country”, “soft power”, economic-centered foreign policy applied. At the beginning of the 21st century, Turkey increased its efforts to act as a voice in the region and emerged as a regional power. Taking a principled position, it began to actively participate in regional and international projects, geopolitical processes and solving global issues. During the rule of the Justice and Development Party (ADP), Turkey is implementing foreign policy principles based on the theory of neo-Ottomanism (New Ottomanism) founded in the 1990s, and is still pursuing the policy of spreading its sphere of influence and geopolitical influence in neighboring regions.
