Turkey is an important power of Middle East and has a glorious past. On the basis of its victorious history, Turkey is aspiring to become a regional power of the region. In this regard, the domestic environment of Turkey (such as stable political system, democratic norms, economic development and political leadership) is playing significant role on one hand. On the other hand, the regional and global environment is also providing some opportunities and challenges to pursue its ambitions actively. Turkey's foreign policy in 21st century can be divided in two main phase; first decade of 21st century in which Turkey mostly relies on the use of soft power. However, in second decade, Turkey has used soft and hard power to gain its goals. Turkey's foreign policy towards Saudi Arabia, Iran and Syria are the key focus of this study. Previously, Turkey avoids supporting Iran and Saudi Arabia against each other. However, now Turkish leadership is actively trying to regain the historical influence of Turkey especially in Muslim world. Turkey's relations with Iran and Saudi Arabia are revolving around cooperation Vs competition paradigm. On one hand, Turkey's support for Qatar (2017) and the killing of Jamal Khashogi (October, 2018) has deteriorated the Saudi-Turkey's relations.
