North Korean leader Kim Jong Un said on Saturday that "under the proven condition of full nuclear weapons, nuclear tests, medium-range and intercontinental ballistic tests are no longer needed and the nuclear test site in the northern area is no longer needed has completed its mission" quotes state news agency KCNA.
The announcement appears to mark a notable change in policy for Kim after his relentless use of nuclear and ballistic weapons as a means of securing the survival of his regime.
It comes only a week before a meeting between Kim and South Korean President Moon Jae-in and a planned historic encounter between Kim and US President Donald Trump – and a few weeks after the North Korean leader met Chinese President Xi Jinping
The US and South Korea welcomed the message that they considered a sign of progress and a promising start to the upcoming talks.
"North Korea has agreed to suspend all nuclear testing and close a large testing ground," Trump tweeted. Look forward to our summit.
"New Chapter" for North Korea

The North Korean leader has recognized that the best way to normalize relations with other countries is the source added However, the analysts emphasized the caution given in Kim's words, not that Pyongyang would likely seek something in return.
"The announcement is significant, but it is a historic, timely opportunity You know if North Korea is really serious remains to be seen, "said Sue Mi Terry, a former CIA North Korea Ana lystin.
"You could search for freeze deals looking for sanctioning facilities. So what will we give for freezing tests?
"North Koreans never give anything away for free, so they're looking for something from us."
CNN military analyst James Marks said it was "phenomenal" that the test freeze could take place, but added that he was "extremely skeptical" about the intentions of the North Korean regime.
"I think what we really see is the pain of the economic sanctions have really begun to run away in its inner circle, and that's the key ingredient here."
"When Kim feels the pain himself, and when inner circle, his elites feel the pain, then he will do it, start being attentive, and I think we see that.
He added that the timing of the announcement following his visit to Beijing indicated that the Chinese leader had influenced the political change.
"Sure, that was Kim, who came to Xi, Xi gave him assurances – look, you have to go back and you have to stop doing certain things. I am back. You will do it. & # 39; OK, but your regime will be wiped out if you continue on this path. "
Marks said that denuclearization" is probably not an option, but what is freezing is and we need to take it. "There."

Six nuclear tests
North Korea did its last nuclear test deep underground last September at the Punggye-ri nuclear test site in the North Hamgyong Province. The explosion produced a magnitude 6.3 tremor, making it the strongest weapon Pyongyang had ever tested.
At that time, Pyongyang claimed that the device was a hydrogen bomb, a type of nuclear weapon that uses explosive force or destructive power instead of nuclear fission. It is also called a thermonuclear bomb.
For years, North Korea has worked to miniaturize a nuclear warhead to fit a long-range missile and survive the heat-intensive process of re-entering the Earth's atmosphere.
Last year, Pyongyang tested a new ballistic intercontinental ballistic missile that was said to reach the entire American mainland, threatening Kim to realistically pursue his threat to the US.
Historic Summits Planned
The planned encounter follows months of warming relationships since Kim introduced an olive branch in this New Year's speech the hand held.
The two countries began talking on a dedicated phone line for the first time in two years, and these talks led to North Korea's participation in the Winter Olympics in South Korea.
Kim invited South Korean President Moon Jae. To go to Pyongyang, and the two agreed to meet next Friday, April 27, in the heavily fortified demilitarized zone (DMZ) between the two countries. Before the talks, a hotline between the two capitals was re-connected on Friday afternoon.
Earlier this week, Trump said he would give his "blessing" for a peace treaty – and said upcoming talks were "a great opportunity to solve a world problem."
Trump's candidate for US Secretary of State CIA Director Mike Pompeo laid the groundwork for the meeting with a secret trip to North Korea three weeks ago. His trip sent a message that both sides are serious about finding a solution to the tensions on the Korean Peninsula.
