President Trump during an interview published Sunday said he had good chemistry with German Chancellor Angela Merkel.
Donald Trump will prioritise the European Union ahead of Britain over free-trade deals with the USA, officials have said.
The White House said the two also discussed the conflicts in Syria and Yemen and the need for a peaceful settlement to the crisis in Ukraine.
However, German finance minister Wolfgang Scauble said on Friday he was optimistic that a US-EU trade deal could be reached soon after he met up with his US counterpart in Washington.
Merkel, speaking at the opening of the 70th annual Hannover Messe trade fair, said Germany was opposed to protectionism and trade barriers, and would continue to work for trade agreements like the one signed between the European Union and Canada.
"On the eleventh refusal, Trump finally got the message", the source added.

The US president was finally convinced it would be easier than he first thought by Angela Merkel, the newspaper said. All signatory states are obligated to do.
The main reason it has been suggested that Trump has had to do something of a u-turn is that his administration has been unable to open talks with any individual European Union member country so far in rewards to possible trade deals other than with the United Kingdom, and that fact has led him to come to the conclusion that a deal would be best put into place with the European Union before the United Kingdom finally leaves the European Union as part of Brexit.
During the first three months of the administration, Ivanka Trump has strived to highlight issues relating to women's economic empowerment.
At the joint press conference held during Merkel's March visit to the U.S., she pointedly took Trump to task for relegating most of his communiques to the one-sided format of social media, notably through his tweets, unambiguously stating, "It's much better to talk to one another than about one another".
Apparently in his talks with Merkel in March, President Trump did not realise he could not make a deal with Germany alone.
