He added that the North Korean leader has made all-out efforts to prepare for the summit with the US, saying his meeting with Trump will serve as a good start.

"The US side's unilateral announcement of the cancellation of the summit makes us think over if we were truly right to have made efforts for it and to have opted for the new path," he said.

Kim emphasized that the North remains open to talks with the US.

"We remain unchanged in our goal and will to do everything we could for peace and stability of the Korean peninsula and humankind, and we, broad-minded and open all the time, have the willingness to offer the US side time and opportunity," he said.

In a publicly disclosed letter to the North Korean leader, Trump said Thursday night (Seoul time) that the cancellation was due to the "tremendous anger and open hostility displayed in your most recent statement."

Trump apparently pointed to the remarks by Choe Son-hui earlier Thursday in which the North's vice foreign minister lambasted US Vice President Mike Pence for bringing up a Libya-style approach in ridding the North of its nuclear program and threatened to walk away from the summit with the US

"I would like to take this expression of his stand on the DPRK-US summit as a decision not consistent with the desire of humankind for peace and stability in the world, to say nothing of those in the Korean peninsula," Kim said.

"As for the tremendous anger and open hostility referred to by President Trump, it is just a reaction to the unbridled remarks made by the US side which has long pressed the DPRK unilaterally to scrap nuclear program ahead of the DPRK-US summit," he added. (Yonhap)
