Special Representative of the U.S. State Department for Ukraine Kurt Volker is convinced that the peacekeeping mission in Donbas will differ in format from all previous ones, Radio Free Europe/Radio Liberty has reported.

Commenting on journalists' words who, having communicated with new adviser to President Donald Trump on national security John Bolton, heard from him strong criticism of the very idea of the peacekeeping mission for Ukraine, Volker said that he had not had an opportunity to discuss this issue with Bolton.

I agree with him [Bolton] that many UN peacekeeping missions are very expensive, often create frozen conflicts instead of solving them. This is a very serious doubt. However, what we are talking about in the case of Eastern Ukraine is completely different. It will not be a traditional UN peacekeeping operation through the United Nations system - it will be based on the voluntary participation of states, Volker explained.

According to the diplomat, he considers the mission for Ukraine exclusively as a transitional mechanism to move from the current situation, when Russia exercises control, to the situation when Ukraine will exercise control.

At the same time Volker doubts that Russia will use the right of veto in the UN Security Council in order to block this peacekeeping operation.
