The Qatar–Saudi Arabia diplomatic conflict refers to the ongoing struggle for regional influence between Qatar and the Kingdom of Saudi Arabia (KSA), both of which are members of the Gulf Cooperation Council (GCC). It is sometimes called the New Arab Cold War. Bilateral relations are especially strained since the beginning of the Arab Spring, that left a power vacuum both states sought to fill, with Qatar being supportive of the revolutionary wave and Saudi Arabia opposing it. Both states are allies of the United States, and have avoided direct conflict with one another.
