Fostering of cooperation between NATO and the European Union (EU) would help to provide larger support to Ukraine, NATO Secretary General Jens Stoltenberg has said.

"The NATO and EU provide support to Ukraine. We provide political support. We provide practical support... We help Ukraine with implementing reforms in defense and security institutions," he said after a meeting of NATO foreign ministers on Tuesday in Brussels.

He said that NATO and the EU will cooperate more tightly in providing support to create the potential and training.

"We can be more efficient," he said.

EU High Representative for Foreign Affairs and Security Policy Federica Mogherini said that EU helps Ukraine with special focus on economic and social reforms, fighting corruption, the judicial system.

"Keeping Ukraine a priority in our agenda not only in Europe but also across the Atlantic, obviously we are also working together in a field that is purely political, a little bit less for the NATO practical work: the full implementation of the Minsk agreements… The intensity and regularity of the meetings we have… to try and solve the conflict in the east of the country," she said.
