"Ukraine will give a list of people directly involved in the organization of the electoral farce in Crimea, as well as of those, who participated in the unlawful elections to all its international partners, so that to include them in the sanctions' lists," the statement said.
The statement added that the elections held in Crimea challenged the legitimacy of the State Duma itself, because of the partially proportionate election system.
Later in the day, former Ukrainian Prime Minister Arseniy Yatsenyuk called on the Verkhovna Rada, the Ukrainian parliament, to recognize Russia's parliamentary elections as illegitimate, and expressed hope that the Verkhovna Rada would discuss the issue on Tuesday.
Crimea reunified with Russia after over 96 percent of the local residents supported the move in the 2014 referendum that followed the coup in Kiev. Ukraine, as well as the West, did not recognize the move and considers the peninsula as an occupied territory.
Since 2014, relations between Russia and the West deteriorated amid the crisis in Ukraine. Brussels, Washington and their allies have introduced several rounds of anti-Russia sanctions since Crimea's reunification with Russia in 2014 and over Moscow's alleged involvement in the Ukrainian conflict.
