The introduction of peacekeepers into Donbas may lead to a freezing of the conflict and will not help restore Ukraine's control over its entire territory, the U.S. ambassador to the UN in 2005-2006 John Bolton has said.

I do not think there should be any peacekeepers in Ukraine. I think, this is a mistake from the point of view of Ukraine. Firstly, it means that you are increasing Russia's role in Ukraine's internal affairs, he said on 112.Ukraine TV channel on the sidelines of the 14th annual meeting of the Yalta European Strategy in Kyiv on Friday.

Bolton noted that now the main discussion is focusing on the means that will help not to freeze this conflict. If you want to restore Ukraine's sovereignty over Donbas, the last thing Ukraine must do is to allow peacekeepers enter Donbas," he said.

The diplomat is also convinced that Ukraine should do everything possible to reduce Russia's pressure on itself.

I think that what Ukraine is doing now is not enough. It is necessary to make much more efforts, he said.
