"The more successful Ukraine is in implementing reforms, the closer Ukraine hopes to meet NATO standards, and the closer you can come to the NATO membership. I cannot give you a specific date. I will only tell you that we will continue to support Ukraine on their Euro Atlantic aspiration, we will support Ukraine, as you can move towards NATO membership. And the best way of doing that is to focus on reforms and to continue to modernise and strengthen the democratic institutions of Ukraine," Jens Stoltenberg said after the meeting with Ukrainian Prime Minister Denys Shmyhal in Brussels.

NATO Secretary General noted that NATO's door remains open.

"Alliance made a decision, back in 2008, about the membership of Ukraine, and We stand by that decision. The focus now should be on the reforms, on the need to continue to reform, to make sure that Ukraine has democratic political control over its defence institutions and the Armed Forces, that continued efforts to fight corruption and to strengthen democratic institutions of Ukraine. This is good for Ukraine, regardless of NATO," stated Jens Stoltenberg.
