"Biden noted that if tensions continue along the Ukrainian border, Western countries will impose large-scale economic, financial, and military sanctions," Ushakov said. "Our president immediately responded to that by saying that if the West decides to impose these unprecedented sanctions under certain conditions, all this could lead to a complete rupture of relations between our countries."
