North Korea has begun returning remains the missing remains of soldiers from the Korean War, President Donald Trump told Fox News' "Fox & Friends" Friday morning during an impromptu interview on the North Lawn of the White House.

North Korean dictator Kim Jong Un agreed during the summit in Singapore on Tuesday, Trump said, to immediately begin returning troops who went missing in action during the Korean War from 1950 to 1953.

Trump said he told Kim he would like to get the American remains being held in North Korea.

"[Kim] said, 'Yes, we will do that,'" Trump explained. "They are already starting to produce the remains of these great young soldiers who were left in North Korea. We're getting the remains."

Prior to the summit, South Korean President Moon Jae-In told reporters that the returning of missing American and South Korean soldiers from the war would be a top priority, American Military News reported.

The discussion about the return of Korean military remains starts at the 13:50 mark:

Have remains been returned in the past?

Efforts to recover missing remains stalled more than a decade ago when U.S. officials couldn't guarantee the safety of American recovery teams sent into North Korea.

Search teams recovered 229 sets of remains between 1996 and 2005, according to Military News.

How many missing remains are there?

There are an estimated 7,800 missing remains from the Korean War, according to the Defense POW/MIA Accounting Agency.

Of those, about 5,300 are believed to have been killed in battles or placed in prisoner of war camps in North Korea.

What else?

In April, Kim and Moon agreed to finally end the 65-year war and denuclearize the Korean peninsula when they signed the “Panmunjom Declaration for Peace, Prosperity and Unification on the Korean Peninsula.”

The two nations plan to convert the 1953 armistice to a peace treaty by the end of the year.
