The Gulf Cooperation Council (GCC) is considered one of the most important regional organizations in the Middle East and North African (MENA) region, which effectively solves some of the crises in the sub-region and the wider Middle East. GCC has employed many diplomatic procedures to address regional crises, including mediation, negotiation, and arbitration. Undoubtedly, GCC has successfully resolved some intrastate conflicts, particularly border conflicts among its member states. However, despite these achievements, the GCC has failed to resolve several regional disputes, and the continuation of such crises threatens the region’s security and stability. This article seeks to explore why the GCC institutions are ineffective in resolving some regional crises. In doing so, it addresses the comparative study by focusing on two case studies (the Iraq–Iran War and the ongoing Yemen Crisis) and provides three main results: first, the GCC has not directly intervened as an institution to resolve certain disputes; however, some GCC members have acted on its behalf and represented it. Second, despite the GCC member states’ efforts, they are still unable to resolve and settle some disputes because they prioritize self-interest over collaboration. Third, the conflict of interest of various regional actors contributes to the lack of significant progress in resolving crises.

海湾合作委员会（GCC）被认为是中东和北非（MENA）地区最重要的区域组织之一，它有效地解决了次区域和更广泛的中东地区的一些危机。海合会采用了许多外交程序来解决地区危机，包括调解、谈判和仲裁。毫无疑问，海合会成功解决了一些国家内部的冲突，特别是成员国之间的边界冲突。然而，尽管取得了这些成就，海合会未能解决一些地区争端，此类危机的持续威胁着地区的安全与稳定。本文旨在探讨为什么 GCC 机构在解决一些地区危机方面效率低下。在这样做，它通过关注两个案例研究（伊拉克 - 伊朗战争和正在进行的也门危机）来处理比较研究，并提供三个主要结果：首先，海湾合作委员会没有直接干预作为解决某些争端的机构；然而，一些海湾合作委员会成员代表它行事并代表它。其次，尽管海合会成员国做出了努力，但他们仍然无法解决和解决一些争端，因为他们将自身利益置于合作之上。第三，各地区行为体的利益冲突导致在解决危机方面缺乏重大进展。尽管海合会成员国做出了努力，但他们仍然无法解决和解决一些争端，因为他们将自身利益置于合作之上。第三，各地区行为体的利益冲突导致在解决危机方面缺乏重大进展。尽管海合会成员国做出了努力，但他们仍然无法解决和解决一些争端，因为他们将自身利益置于合作之上。第三，各地区行为体的利益冲突导致在解决危机方面缺乏重大进展。
