Ukrainian Foreign Minister Pavlo Klimkin has said Ukraine is a part of the eastern flank of the North Atlantic Treaty Organization (NATO).

"We are in a situation where we must support and be true to our values. This is Ukraine now – if not de jure, then politically – a part of NATO's eastern flank, because we are fighting in Donbas to support our values and defend the free world," Klimkin said during a conference, dubbed "Kyiv's Transatlantic Dialogue," in Kyiv on Tuesday.

According to Klimkin, NATO observes clearly defined and understandable principles, which are written in the military bloc's statutes.

"Values, principles and faith – this is why NATO is necessary for the free world," Klimkin.
