CHRISTINE LAGARDE- How negotiations with Putin differ from negotiations with Trump

The President of the European Central Bank, Christine Lagarde, talks to Sandra Maischberger about Vladimir Putin.
'With one you need to know everything, and with the other you need to be patient and smile' - European Central Bank President Christine Lagarde explained how negotiations with Putin differ from negotiations with Trump.
“Putin is incredibly thorough, he values ​​time. He is truly educated and informed. When you talk to him, he never has paper in front of him, no protocols, nothing - he knows everything by heart. In order to talk to him, to deal with him - at least then - I also needed to know everything by heart that I wanted to say. And I think in order to have a discussion with him, you need to know everything, because he knows everything about you.”
And with Donald Trump, it's the other way around, isn't it? [Lagarde smiles and sighs] I'll simplify. When you were a swimmer, you said: 'In this sport, you learn to grit your teeth, endure and smile.' Does that help when dealing with Donald Trump?
