"Our preference is not to have sanctions [against Russia] but the sanctions will be there in an effort to try to secure the peace that everybody wants in Ukraine," Kerry said Wednesday before a meeting of NATO foreign ministers in Antalya, Turkey.
According to him, now it is critical to take actions to fulfill the Minsk agreements.
"This is an enormous moment of opportunity for the conflict there to find a path of certainty and resolution."
The United States, the European Union and their allies introduced several rounds of economic sanctions targeting Russia's banking, energy and defense sectors, as well as certain individuals in 2014 over Russia's alleged involvement in Ukrainian internal conflict. The restrictive measures also include asset freezes and travel bans for blacklisted individuals.
