"We can not know for sure that North Korea killed Mr. Warmbier", Mr Moon said in an interview with CBS.
"I believe we must now have the perception that North Korea is an irrational regime", said Moon, who was elected in May.

2am BST: The US ambassador to the UN, Nikki Haley, has said Otto Warmbier's death shows the inhumanity of the North Korean dictatorship. However, it has been said that it would be at least a year before evaluating how successful China has been.
China-based Koryo Tours, which has been going to North Korea since 1993 and takes about 2,000 tourists there a year, said the tragedy had prompted it to reconsider taking USA citizens to the North.
"No conclusions about the cause and manner of Mr. Warmbier's death have been drawn at this time as there are additional medical records and imaging to review and people to interview", the coroner's office statement said, expressing "deepest sympathies" for his family and friends.
Former President Barack Obama has released a statement on Otto Warmbier. "Our deepest sympathies are with the family and friends of Mr. Warmbier at this time of their tragic loss". That is particularly true when the official brings home a newly freed American captive.
Trump's statement, delivered in an nearly cavalier tweet on Tuesday, was an extraordinary admission of failure in his strategy for dealing with the North Korean regime of Kim Jong-un, New York Times said.

"And frankly, if he were brought home sooner, I think the results would have been a lot different", Trump said during a White House meeting with Ukrainian President Petro Poroshenko.

Secretary of State Rex Tillerson and Secretary of Defense James Mattis will host China's top foreign policy official and chief of joint staff of the military at the State Department today, where tougher sanctions on North Korea is expected to be a top subject.
It is unclear if the USA would be open to talks with North Korea.
It was unclear if his tweet was a signal that those efforts are perceived to have failed.
Trump said on Twitter on Tuesday he appreciated efforts by Chinese President Xi Jinping "to help with North Korea", adding "It has not worked out". "There's no way for me to know that for sure".
But other analysts said that however horrific the case might be, the Trump administration was unlikely to let it upset the momentum toward dialogue it has built.
