At the moment, it is not known when new negotiations with the Russian Federation will take place, said Ukrainian Foreign Minister Dmytro Kuleba.

"We are ready for negotiations, we are ready for diplomacy, but we are by no means ready to accept any Russian ultimatums. It is unknown at the moment when the new negotiations will take place," Kuleba said on his Facebook on Wednesday.

He added that the demands of the Russians remain unchanged. "These are the demands that Putin voiced in his address before the start of the war, in fact declaring war on us," Kuleba said.
