"It doesn't work that way. There is no clear list of criteria, after which the MAP or membership is granted - because these are political decisions, these are not purely technical criteria ... I am not saying that there is no connection between reforms and a political decision - of course, they are but just fulfillment of the list of conditions is not enough in itself," he said.
In addition, Appathurai added that not only Ukraine should be ready to join NATO, but the alliance should be ready to expand.
Earlier, President Volodymyr Zelensky said that Ukraine wanted to receive a clear list of reforms needed for NATO integration.
"13 years after the Bucharest NATO summit, the period of uncertainty must end and the implementation of confirmation of the political decision on Ukraine's future membership in NATO should begin. We will continue to do our best to accelerate reforms in Ukraine, including through annual national programs. But today we would like to receive a list of reforms, the implementation of which will allow Ukraine to move to the next step - to integration with the alliance," Zelensky said.
