Donald Trump returning to the White House would be “a once-in-a-thousand-year opportunity” for North Korea, according to Ri Il Kyu, the highest-ranking defector to escape North Korea since 2016 and has been face to face with Kim Jong Un on seven separate occasions.

The former diplomat, who was working in Cuba when he fled with his family to South Korea last November, says that the regime in North Korea still views Mr Trump as someone it can negotiate with over its nuclear weapons programme, despite talks between him and Kim Jong Un breaking down in 2019.

Mr Trump has previously hailed the relationship with Kim as a key achievement of his presidency. He famously said the two “fell in love” exchanging letters. Just last month, he told a rally Mr Kim would like to see him back in office: “I think he misses me, if you want to know the truth.”

North Korea is hoping it can use this close personal relationship to its advantage, says Mr Ri, contradicting an official statement from Pyongyang last month that it “did not care” who became president.

The nuclear state will never get rid of its weapons, Mr Ri says, and would probably seek a deal to freeze its nuclear programme in return for the US lifting sanctions.

But he says Pyongyang would not negotiate in good faith. Agreeing to freeze its nuclear programme “would be a ploy, 100% deception”, he says, adding that this was therefore a “dangerous approach” which would “only lead to the strengthening of North Korea”.
