US President Donald Trump says he will meet Kim Jong Un later this year, seeking to revive the bond he claims to have struck with the leader of nuclear-armed North Korea in his first term.

President Trump said he plans to meet with Kim Jong Un this year as Trump is once again touting his close relationship with the North Korean leader.

“I know Kim Jong Un very well, and he's going to be fine as long as we have a smart president,” he tells reporters.
