Ukraine rejected calls from Moscow and Washington to commit to engaging in peace talks with Russia next week, demanding to see Russian peace proposals before attending further negotiations. In nationally televised remarks on Friday, Ukrainian President Volodymyr Zelenskyy’s chief of staff, Andriy Yermak, said Kyiv is dedicated, in principle, to continued peace negotiations with Russia. However, he stopped short of agreeing to the proposed Monday peace talks in Istanbul. “We are ready for dialogue, but we demand clarity — clear and, most importantly, balanced proposals,” Mr. Yermak said.
