President of Ukraine Volodymyr Zelensky has said that American and European politicians should respond with sanctions against the entire banking system of Russia for its attempt to introduce a ruble zone in the temporarily occupied territories of southern Ukraine.

"The invaders are trying to tear off Kherson and Zaporizhia regions, following the example of the so-called "DPR" and "LPR." They are switching to the ruble zone and subordinating the administrative machine of Russia on this territory. All this requires greater speed of Western states in preparing a new powerful sanctions package. In response to an attempt to occupy Kherson and Zaporizhia regions in rubles should be the full coverage of the Russian banking and financial systems, because they are part of the occupation machine," Zelensky said in an evening video message on Sunday evening.

Also, according to him, the need to impose an embargo on the supply of oil from the Russian Federation is growing every day.

"Everyone in the United States and Europe already sees that Russia is openly using energy to destabilize Western society. The Russian bet on chaos in the fuel markets should not work," he added.
