Donald Trump: 'Charming, courteous... intimidating'

Donald Trump has said the United States will "solve" the nuclear threat from North Korea, with or without China's help.

"If China is not going to solve North Korea, we will. That is all I am telling you," he said in an interview with UK paper the Financial Times.

Lionel Barber, editor of the Financial Times, carried out the interview. He told the Today programme there's a range of options being considered to solve the threat.
