He conceded that the North Korean dictator was a "pretty smart cookie" and shrugged off a recent failed missile launch on their part, telling John Dickerson: 'Eventually, he'll have good missiles'.
In a wide ranging interview for Face The Nation on CBS, he said he had not yet decided on whether the U.S. would launch military action against Kim Jong Un, but said he didn't want to give away "all our moves" anyway. And he was able to do it.
Despite that, Trump said he would be "honoured" to meet the North's young leader.
Separately, Trump's national security adviser, Army Lt. Gen. H.R. McMaster, said North Korea's most recent missile test represents "open defiance of the worldwide community".
Trump's comments come after North Korea carried out a test-launch of what USA officials said was a short-range ballistic missile, a test banned under United Nations sanctions.
North Korea is seeking to develop a long-range missile capable of hitting the U.S. mainland with a nuclear warhead.
President Donald Trump has warned he will be ready to take action when North Korea successfully develops missiles after its latest test failed again.
When asked if the United States was to blame for Pyongyang's failed blast, President Trump remained coy. And I will tell you, a man that I've gotten to like and respect, the president of China, President Xi, I believe, has been putting pressure on him also. The missile test came just as Japan started a series of holidays known as Golden Week.
Trump said he had "no idea" whether Kim was sane or not, but said the North Korean leader had faced a formidable challenge in taking over the country at a reported age of 27 after his father's death in 2011.

He added: "And if that happens, we can't allow it to happen".

North Korea on Saturday said it is developing nuclear weapons for self-defense and as a deterrent to the United States, according to an unofficial translation of a statement released by an official in Pyongyang's mission to the UN.
Trump cast the launch as a direct snub of China, one of North Korea's only allies and a nation seen by the Trump administration as a potential U.S. ally in efforts to stamp out Pyongyang's nuclear program.
Trump raised eyebrows in South Korea last week when he said would make Seoul pay $1 billion for the missile defense system.
