Former German Chancellor Angela Merkel spoke about the newly elected US President Donald Trump in an interview with the BBC.
Merkel, who has worked with Trump, advises European leaders on how to negotiate with him.
"Donald Trump does not believe that there can be situations where all sides win. He is convinced that there will be only one winner. That is why negotiations with him are more difficult. It is important to formulate priorities clearly, and mutual respect will be formed," the former chancellor said.
