“We don’t return our territories. Crimea is a territory of the Russian Federation,” Zakharova said at a weekly news briefing on current foreign policy issues.

“President Trump has made it very clear that he expects the Russian government to de-escalate violence in the Ukraine and return Crimea,” Spicer said. “At the same time, he fully expects to – and wants to – get along with Russia.”

Earlier in February, the Trump-appointed ambassador to the UN, Nikki Haley, strongly denounced "the Russian occupation” in Crimea.

“Crimea is a part of Ukraine. Our Crimea-related sanctions will remain in place until Russia returns control of the peninsula to Ukraine,” Haley said.

Crimea became part of the Russian Empire back in the 18th century, but was reassigned to the Ukrainian Soviet Socialist Republic in 1954 by the Soviet Union’s ruling presidium. Following the 2014 coup in Kiev, Crimeans overwhelmingly voted in a referendum to rejoin Russia.
