Presumptive US Republican presidential candidate Donald Trump says he is willing to meet North Korea's leader to discuss its nuclear programme.
"I would speak to him, I would have no problem speaking to him," the businessman said of Kim Jong-un.
Such a meeting would mark a significant change of US policy towards the politically isolated regime.
Democratic front-runner Hillary Clinton decried Mr Trump's "bizarre fascination with foreign strongmen".
The statement, delivered by one of her aides, added that Mr Trump's foreign policy "made no sense".
In a separate interview with Fox News, Mr Trump said he "absolutely had regrets" about his nine-month campaign, but that if had not conducted himself in the way he had, he would not have been successful.
