Putin's indication of ceasefire - talk to whom?

Vladimir Putin, the president of Russia, has consented to a diplomatic ceasefire and the conclusion of the conflict in Ukraine. Zelensky's five-year presidential term is over. However, new polls are not being held in the war-torn Ukraine since martial law is in effect there. In this case, there will be a legal barrier if Russia and Ukraine meet for peace negotiations. Putin asked, "He" will negotiate with whom, pointing to the peace negotiations.
