'Friendly' walk away suggests there is more talking to be done

After his meeting in Hanoi with Democratic People's Republic of Korea top leader Kim Jong-un was cut short on Thursday, United States President Donald Trump said that "sometimes you have to walk", and that "this was just one of those times".

Although "it was a friendly walk", he added.

Certainly the two leaders greeted each other with warm smiles and handshakes when they met on Wednesday, and they exchanged friendly words over dinner that evening.
