MOSCOW, Oct 4 (Reuters) - The Kremlin praised Tesla boss Elon Musk on Tuesday for suggesting a possible peace deal to end the war in Ukraine, after Kyiv rebuked Musk for proposing terms it views as rewarding Russia."It is very positive that somebody like Elon Musk is looking for a peaceful way out of this situation," Kremlin spokesman Dmitry Peskov told reporters in a conference call.Kyiv says it will never agree to cede land taken by force, and lawful referendums cannot be held in occupied territory where many people have been killed or driven out.After Vladimir Putin announced the annexation of four Ukrainian provinces last week, Kyiv said it was applying to join NATO, and would not negotiate with Russia as long as Putin is president.He criticised a new Ukrainian decree, signed by Zelenskiy on Tuesday, which says Kyiv will not negotiate directly with Putin for an end to the conflict."
