"Crimea return strategy should be based on two main premises. This is the return of people, their cultural, physical, mental and economic return. And secondly, this is the prevention of legitimization of illegal Russian occupation of Crimea," Petukhov said during Parliamentary hearings titled "The strategy for the reintegration in Ukraine of the temporarily occupied territory of the Autonomous Republic of Crimea and the city of Sevastopol: problems, ways, methods and efforts.”

According to the Ukrainian official, it is necessary to make sure that the people who remained in Crimea, felt Ukraine’s care and the bond with it. In this regard, Petukhov noted in particular the procedure for obtaining the documents by Crimea residents.

"In addition, we must ensure that these people can cross the administrative border without any problems, within the limits which ensure Ukraine’s national security, but this should not create additional restrictions for these people," said the representative of the ministry.

And here I can say that there are some developments. Despite the fact that Russia has twice postponed the submission of its objections on the position of Ukraine, they were finally forced to do it. We got these objections. They are quite formal. Now things are moving on, and before late August, Ukraine should submit its comments on these objections, after which the court may proceed to consideration of the case on the admissibility of the first inter-state case, which deals specifically with the events in Crimea," he said.
