North Korean leader Kim Jong Un said he would halt nuclear tests and intercontinental missile launches, in a Saturday announcement welcomed by US President Donald Trump ahead of a much-anticipated summit between the two men.
The Foreign Ministry's statement asserted Egypt's stance for not using or seeking violence in foreign affairs, and its dependence on peaceful settlements of worldwide conflicts.
While North Korea's statement could indicate a positive step toward lowering tensions on the Korean Peninsula, it falls short of saying it would scrap its existing missiles or nuclear weapons.
His tweet said: "A message from Kim Jong Un: 'North Korea will stop nuclear tests and launches of intercontinental ballistic missiles.' Also will 'Shut down a nuclear test site in the country's Northern Side to prove the vow to suspend nuclear tests'".
Thornton, who's in charge of preparing the upcoming summit between her country and North Korea, will also hold talks with Lee Do-hoon, South Korea's top nuclear negotiator, the following day, to exchange views on agendas related to the North.
But he also said the inter-Korean summit had "a lot of constraints", in that the two Koreas could not make progress separate from the North Korea-United States summit, and could not reach an agreement that transcends global sanctions.
North Korea says it has suspended nuclear and long-range missile tests and plans to close its nuclear test site.
But Kim offered no sign he might be willing to give up what he called the North's "treasured sword", saying its possession of nuclear weapons was "the firm guarantee by which our descendants can enjoy the most dignified and happiest life in the world".

Within minutes of the report being issued, Trump tweeted: "This is very good news for North Korea and the World - big progress!"
Analysts cautioned that the declaration was promising but limited.
In the statement released by his Spokesperson, Guterres described Kim's decision as "a positive step forward".
"Our campaign of maximum pressure will continue until North Korea denuclearises", he added.
North Korea further claimed that a nuclear test center "will be discarded in order to ensure the transparency of the suspension of the nuclear test".
North Korea has always been a source of worry for the world at large.
"As I've said before, there is a bright path available to North Korea when it achieves denuclearisation in a complete and verifiable and irreversible way".
According to him, it will contribute to building trust between the North Korea and its southern neighbour, South Korea, as well as other countries in the region.
The North's decisions were made in a meeting of the ruling party's full Central Committee which had convened to discuss a "new stage" of policies.
