Ukraine President Volodymyr Zelenskyy has said talks are "confrontational" but moving forward. But on Wednesday, Ukraine's delegation said negotiations with Russia hit major difficulties, and it was echoed by Russian Foreign Minister Sergey Lavrov. Lavrov blames Western countries for sending weapons to Ukraine, saying Moscow believes the U.S. is hampering the peace talks. Lavrov says the West's ultimate goal is to preserve a unipolar world, and that Ukraine is being used as a tool to constrain Russia.
