Washington-brokered negotiations to end Russia’s war in Ukraine have largely boiled down to a diamond-shaped peninsula about the size of Massachusetts.

Amid reports that a U.S. peace proposal might include recognizing Moscow's illegal annexation of Crimea, President Donald Trump denied Ukraine was being pressured to accept the move — while also asserting Ukraine had given up the peninsula in 2014 "without firing a shot.

The Russian Federation demands to recognize Crimea as part of its territory in order to disrupt negotiations on ending the full-scale war, said Borys Babin, an expert from the “Reintegration of Crimea” Association in the material by RBC-Ukraine "Trump changing the game: Why Crimea suddenly came up in peace talks".

US officials have prepared a set of options for President Donald Trump to increase economic pressure on Russia, according to people familiar with the matter, as President Vladimir Putin drags his feet over attempts to end the war in Ukraine.
