2017年卡塔尔断交危机使相对稳定的海湾地区成为各方关注的焦点。从发展历程看，这场危机经历了关系恶化、单方面缓和、再度恶化三个发展阶段。从根源看，这场危机既有沙特储位之争，也有地区领导人权力博弈，还有相关各方利益角逐。从前景看，这场断交危机的发展走向依然充满变数。
Qatar's diplomatic crisis in 2017 has brought the relatively stable Gulf region into the focus of attention.

The future of the diplomatic crisis is still full of uncertainties.
