On Friday, North Korean leader Kim Jong-un announced that the nation is suspending missile and nuclear tests and is closing a nuclear test facility ahead of the anticipated meeting with President Donald Trump.

“From April 21, North Korea will stop nuclear tests and launches of intercontinental ballistic missiles,” the Korean Central News Agency said, according to Yonhap News Agency. “The North will shut down a nuclear test site in the country’s northern side to prove the vow to suspend nuclear test.”

In response, Trump tweeted: “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.”
