North Korea's nuclear test site will close in May, the South Korean President's Office has said.
A spokesperson said the closure of the Punggye-ri site would be done in public and foreign experts from South Korea and the US would be invited to watch.
On Friday, North Korean leader Kim Jong-un and South Korea's President Moon Jae-in agreed to work to rid the Korean peninsula of nuclear weapons.
Their summit came after months of warlike rhetoric from the North.
Yesterday, US President Donald Trump said he would likely hold talks with the North Korean leadership "over the next three or four weeks" about the denuclearization of the peninsula.
