On March 13, according to the British Daily Telegraph, sources said that Russia has presented the United States with a list of demands for an agreement to end the conflict in Ukraine. The specific demands are not clear, but the sources said that these demands are broadly similar to those previously made to the United States, NATO and Ukraine. < b > These demands include that Kiev must not join NATO, while NATO must not deploy foreign troops in Ukraine, and that the international community recognizes Crimea and four Ukrainian provinces as Russian territory. The United States has been urging Russia to accept its peace offer earlier this week, which would implement a ceasefire in the sky, in the air and across the front line. Trump also threatened to impose "devastating" economic penalties on Russia if it does not accept the offer.
