South Korea's national security adviser Chung Eui-yong said President Trump has agreed to meet with North Korean leader Kim Jong un, and the North is "committed" to denuclearization. The meeting is intended to take place by May.

Chung also said Kim Jong un has agreed to refrain from nuclear testing, and routine joint military exercises between the North and South will continue as planned.

The announcement was made at the White House after President Trump walked into the White House briefing room Thursday and told reporters that South Korea would be making a major announcement at 7 p.m. He added that he has spoken with South Korean President Moon Jae-in.

"South Korea is going to be making a huge statement tonight on a big subject ... on a big subject...on North Korea," said Mr. Trump, according to CBS News Jacqueline Alemany. Journalists were instructed by the president to turn off their cameras. South Korean news agency Yonhap reported that the South Korean national security adviser, Chung Eui-yong, would be holding a joint press briefing with White House press secretary Sarah Sanders at the White House at 7 p.m.

South Korean officials who met with North Korean leader Kim Jong Un this week were to meet with Mr. Trump Thursday, Reuters reported, citing a South Korean presidential official. National security adviser H.R. McMaster met with his South Korean counterpart Chung Eui-yong Thursday afternoon, to be briefed on North Korea's offer, according to a White House official.

On Tuesday, South Korea said that the North had agreed to impose a moratorium on tests of nuclear weapons and missiles if it holds talks with the United States. South Korea's presidential national security director said Tuesday that North Korea said it's ready to have "heart-to-heart" talks with the United States on issues regarding the North's potential denuclearization and the normalization of relations between Pyongyang and Washington.
