REPUBLICAN renegade Donald Trump claims he knows how to make North Korean leader Kim Jong-un “disappear”.

The presidential candidate said he would work with emerging superpower China to deal “economically” with the rogue Asian nation.

“I would get China to make that guy disappear in one form or another very quickly,” Trump told CBS, fresh off his victory in New Hampshire’s primary.

When asked if was calling for Kim Jong-un’s assassination, the billionaire businessman shrugged.

“Well, you know, I’ve heard of worse things, frankly. I mean this guy’s a bad dude — and don’t underestimate him,” he said.

“Any young guy that can take over from his father with all those generals and everybody else that probably wants the position, this is not somebody to be underestimated.”

Trump said that China has “absolute control” of North Korea and has a responsibility to rein in the pariah country.

“China is sucking us dry. They’re taking our money, they’re taking our jobs and doing so much. We have rebuilt China with what they’ve taken out. We have power over China. China should do that,” Trump said.

North Korea made headlines earlier this week after launching an Earth satellite into orbit via the long-range Kwangmyongsong carrier rocket. Both the test and the launch were carried out in defiance of international sanctions.

Officials said that, unlike in previous launches, the rocket booster appeared to have been fitted with a self-destruct device to prevent other parties from studying its capabilities.

In January, the North Koreans claimed to have successfully tested a hydrogen bomb in its fourth nuclear test.

Trump is in South Carolina campaigning after winning the Republican primary in New Hampshire on Tuesday.

“We won it big. ... We won by a lot — a really lot,” he said to roaring applause from a crowd of about 3,000. “I got like one hour of sleep … because when you have victory you don’t need sleep.”
