Russian President Vladimir Putin promised Friday to “immediately” order a cease-fire in Ukraine and begin negotiations if Kyiv started withdrawing troops from the four occupied Ukrainian regions and renounced plans to join NATO.

Such a deal appears a nonstarter for Kyiv, which wants to join the military alliance and has demanded that Russia withdraw its troops from all of its territory.

“We will do it immediately,” Putin said in a speech at the Russian Foreign Ministry in Moscow.

His remarks came as leaders of the Group of Seven leading industrialised nations met in Italy and as Switzerland prepared to host scores of world leaders -- but not from Moscow -- this weekend to try to map out first steps toward peace in Ukraine.
