At Bucharest Summit 2008 it was made clear that NATO’s doors are open to Ukraine: "I hope that at the summit to be held in Warsaw next year, it will be also supported by concrete decisions," Prime Minister of Ukraine Arseniy Yatsenyuk emphasised following a meeting with NATO Secretary General Jens Stoltenberg in Kyiv.

The Prime Minister stressed that the position of the NATO member states "was crucial in terms of support and protection of territorial integrity, independence and sovereignty of the Ukrainian state": "NATO and Alliance member states were almost the first who condemned the Russian military aggression against Ukraine, the illegal annexation of Crimea and military intervention in Donetsk and Luhansk by Russian aggressors."
