Donald Trump says that Danish prime minister Mette Frederiksen called him and they had ‘a great conversation,’ as he dialed back an assault on the U.S. ally he called ‘nasty’ over her refusal to sell Greenland.

‘She called me, a wonderful woman, we had a great conversation, we have a very good relationship with Denmark, and we agreed to speak later,’ he said Friday evening. ‘But she was very nice. she put a call in, and I appreciated it very much.’

Frederiksen’s office said Friday the two leaders spoke late Thursday, and Danish media reported the call was ‘constructive.’ The White House had not confirmed the call, but it is believed to be the first time the two spoke since Trump announced he was scrapping his two-day state visit.
