Moon in a statement read out by his spokesman today also complimented Trump for accepting Kim's invitation for a summit, saying Trump's leadership will be praised "not only by the residents of South and North Korea but every peace-loving person around the world."
Moon is also preparing for a summit with Kim at a border village between the Koreas in April.
Trump agreed to meet with Kim by the end of May. The meeting would be unprecedented during seven decades of animosity between the US and North Korea.
