The EU will impose massive sanctions against Russia in coordination with its partners, "should the situation in Ukraine deteriorate," European Commission President Ursula von der Leyen said.
"We reaffirm our solidarity with Ukraine. If the situation deteriorates, we will come with massive sanctions, coordinated with partners," she tweeted.
Meanwhile, she added that the EU supports dialogue with Russia.
"We support dialogue with Russia but do not accept attempts to divide Europe into spheres of influence," she noted.
