According to RIA Novosti, he wrote about this in his Telegram.

“The work of the anti-terrorist commission to identify the property of foreign citizens and states that commit unfriendly actions against Russia continues on the territory of the Republic of Crimea.

Deputies of the State Council will make a decision on the nationalization of this property in the coming days," Konstantinov said.

So, for example, according to him, the property of oligarchs Rinat Akhmetov and Igor Kolomoisky, Ukrainian politician Arseniy Yatsenyuk, Rada deputy Nestor Shufrich, etc. will soon be nationalized. 

“The property of a number of Ukrainian banks and factories is also subject to nationalization, including JSC Alma Building Materials Plant (owner - Sergey Taruta), JSC Kamysh-Burun Iron Ore Plant,” he added.

In October, the head of Crimea, Sergei Aksyonov, ordered the nationalization of the property of a number of organizations and individuals associated with the Kyiv regime located in Crimea.
