From April 21, North Korea will stop nuclear tests and launches of intercontinental ballistic missiles," South Korea's Yonhap news agency quoted North Korean state media as saying on Saturday.
US President Donald Trump hailed the development in a tweet on Friday, saying, "North Korea has agreed to suspend all Nuclear Tests and close up a major test site. This is very good news for North Korea and the World - big progress! Look forward to our Summit."
The news comes amid a flurry of diplomatic efforts by North Korea to improve ties with its neighbors, chiefly South Korea.
On Friday, Seoul and Pyongyang established a hotline just one week before a planned landmark meeting between Kim and South Korean President Moon Jae-in on the southern side of the Demilitarized Zone.
The South Korean president said on Thursday it was time for the two countries to sign a peace treaty.
A possible meeting between Kim and President Trump is also being planned to be held in late May or early June.
Washington and Pyongyang have no diplomatic relations. The US has imposed many rounds of sanctions on North Korea, has substantial military presence near the country, and numerously threatened to invade it.
Tensions on the Korean Peninsula were running high in 2017. Trump’s threats last year prompted North Korea to carry out its most powerful nuclear test to date and launch intercontinental ballistic missiles capable of reaching the United States
But Kim expressed sudden interest in the resolution of disagreements with the South on New Year’s Day, and a series of overtures began.
