WASHINGTON - President Donald Trump will accept an invitation to meet North Korean leader Kim Jong Un at a place and time to be determined, White House spokeswoman Sarah Sanders said on Thursday.

"President Trump greatly appreciates the nice words of the South Korean delegation and President Moon. He will accept the invitation to meet with Kim Jong Un at a place and time to be determined. We look forward to the denuclearization of North Korea. In the meantime, all sanctions and maximum pressure must remain," she said in a statement.

Kim has committed to "denuclearization" and to suspending nuclear or missile tests, South Korea's National Security Office head Chung Eui-yong told reporters at the White House after briefing Trump on South Korean officials' meeting with Kim on Monday.

"I told him (Trump) that in our meeting that North Korean leader Kim Jong Un said that he's committed to denuclearization," Chung said. "Kim pledged that North Korea will refrain from any further nuclear or missile tests."

A meeting between Kim and Trump, who have exchanged bellicose insults in the past year that have raised fear of war, would mark a dramatic breakthrough in efforts to resolve the tense standoff over North Korea's effort to develop a nuclear-tipped missile capable of hitting the U.S. mainland.
