"The notion that we can simply ratchet up sanctions further and further and further and then ultimately Putin changes his mind, I think is a miscalculation," Obama said.
Obama said he did not support the idea of introducing additional sanctions against Russia without coordinating them with European allies.
Barack Obama, speaking at a meeting of the Export Council with the participation of the leaders of American business, said that such an approach may lead to disagreements between the US and the EU. For the United States and Europe, it is important to maintain the unity on the issue of sanctions against Russia. "If they see that there aren't any cracks in the coalition, then over time, you could see them saying that the costs to their economy outweigh any strategic benefits that they get," he said.
