No sign of North Korea dismantling nuclear weapons programme, Mattis admits

However, asked on Wednesday if he could “put his finger on” any steps North Korea had taken to dismantle its nuclear weapons programme, Mattis told reporters at the Pentagon: “No, I’m not aware of that.”

He added: “The detailed negotiations have not begun. I wouldn’t expect that at this point.”

After the Singapore meeting Trump said that his secretary of state, Mike Pompeo, and national security adviser, John Bolton, would take part in follow-up meetings with North Korean officials this week to “go into the details” of the denuclearisation agreement the president believed he had struck with Kim.
