Forever the Frenemies of the Middle East? Türkiye’s Regional Relations with Iran, 2002 to 2023

This article investigates the puzzle of Türkiye’s fluctuating relations with Iran since the Justice and Development Party (AKP) came to power in 2002. Contrary to many scholars’ expectations, the AKP government’s relations with Iran have competition and rivalry rather than just cooperation. Having improved significantly in the early 2000s, the relations became tense following the Arab uprisings and Syria’s civil war. However, the relations between the two countries have included both cooperative and conflictual elements since 2016. This research argues that the most relevant level for analyzing Türkiye’s fluctuating foreign policy strategies toward Iran between 2002 and 2023 is regional. Using the regionalist approaches of Buzan and Wæver’s Regional Security Complex Theory (RSCT) and Lake and Morgan’s theory of regional orders, the article examines how the “local security externalities” of the Middle Eastern regional security complex (RSC) affect Türkiye-Iran regional relations by particularly focusing on speech acts of Turkish high-level foreign policy actors. By acknowledging the multi-layered nature of Middle Eastern politics, this study also considers the role of extra-regional actors and non-state armed groups in Turkish foreign policy attitudes toward Iran.
