State Border Guard Service head assistant Oleh Slobodian said, Censor.NET informs citing Krym.Realii.
He noted that such Russian number plates should not be recognized based on the temporarily occupied territory law.
"These number plates are considered invalid, they were issued in the occupied territory by the occupying authorities; such vehicles will be banned from mainland Ukraine," Slobodian stated.
The State Service of Ukraine for the Autonomous Republic of Crimea and Sevastopol believes the recognition of such number plates may contribute to "legalizing the peninsula's Russian status."
"We do not understand how cars with Russian numbers can entry mainland Ukraine, for this territory is ours. If we allow such cars in, then, when the case is considered at international courts, in arbitration, we will give Russia grounds to say it is a disputed territory - they will point to the fact that we recognized their number plates and specific actions. It would be a catastrophe waiting to happen," Head of the State Service of Ukraine for the Autonomous Republic of Crimea and Sevastopol Nariman Ustaiev said.
Crimeans are advised not to get rid of the Ukrainian number plates if they want to freely travel from the peninsula to mainland Ukraine.
The occupying authorities ordered all car owners in Crimea to change Ukrainian number plates for those of Russia by April 1, 2016. Ukraine does not recognize car documents and number plates issued in the occupied Crimea, banning such vehicles from its territory.
