The Russian Crimea traditionally pays no attention to this.
As stated in the message on Twitter page of the U.S. Embassy in Kiev, the embassy condemns and does not recognize the Russian Federation holding elections in Crimea on September 13.
“We condemn and do not recognize the so-called elections held in the Crimea and Sevastopol on September 13. Once again, Russia violated the sovereignty of Ukraine on the territory which Russia forcibly seized and tried to annex. The sanctions will continue until Russia gives Ukraine back control of the Crimea and gets out of Donbass”, – the embassy said.
The American Embassy regularly places such ritual messages after any events in Crimea. They have no legal meaning, and in reality, apart from expressing support for their puppet regime in Kiev, they do not contain any other meaning.
