Ukraine's Foreign Ministers Pavlo Klimkin and United States Secretary of State John Kerry met in Belgrade, Serbia, on Thursday, and discussed the situation in Donbas and implementation of the Minsk agreements.

The meeting was held on the sidelines of a meeting of the Ministerial Council of the Organization for Security and Co-operation in Europe, the Ukrainian Foreign Ministry said.
