Dmitry Shugaev, director of the Federal Service for Military-Technical Cooperation of Russia, spoke about this in an interview with RIA Novosti.

According to him, all countries that have announced the transfer of Russian and Soviet military products to Ukraine have been sent official notes on the inadmissibility of such actions.

“A number of enterprises located in Bulgaria and the Czech Republic have revoked licenses for the right to repair Mi-type helicopters,” Shugaev said.

He added that Russia also suspended the supply of spare parts and components for aviation and other domestically produced equipment to unfriendly countries.

In May, the Pentagon announced that the Czech Republic had transferred fire support helicopters, tanks and missile systems to Ukraine.
