美国一位高级外交官员表示，针对俄罗斯参与乌克兰危机的制裁，在有关乌克兰的不断遭到破坏的停火协议彻底落实之前，不会停止。
美国助理国务卿纽兰星期六同时还警告莫斯科，进一步违犯明斯克协议将给俄罗斯政府带来更多的“代价”。
纽兰是在于乌克兰首都基辅召开的一次由乌克兰和其他一些国家的政商界领袖出席对策会议上，发表上述讲话的。
她说：“一旦明斯克协议完全得到落实，包括乌克兰领土得以恢复完整，我们可以开始撤销一些制裁。”
美国和欧盟指责莫斯科在背后煽动乌克兰东部亲俄罗斯的反叛活动，并实施了一系列针对俄罗斯军事以及后勤方面参与的制裁方案。
A top U.S. diplomat says sanctions against Russia for its role in the Ukraine crisis will remain in place until a long-violated truce agreement is fully honored.
U.S. Assistant Secretary of State Victoria Nuland also warned Saturday that Moscow will pay "more costs" for future violations of the Minsk peace deal.
Nuland spoke in the Ukraine capital, Kyiv, to a gathering of Ukrainian and foreign political and business dignitaries.
"If and when Minsk is fully implemented, including [the] return of Ukraine sovereignty of its border, we can begin to roll back some sanctions," she said.
The United States and the European Union have accused Moscow of stoking the 17-month pro-Russian rebellion in Ukraine's east, and have imposed a series of economic sanctions aimed at deterring Russian military and logistical involvement.
