The confirmation comes almost two months after North Korea agreed to return 55 boxes of remains to the United States following a meeting between President Donald Trump and communist dictator Kim Jong-un in Singapore.
Pentagon spokesman Colonel Rob Manning said the United Nations delegation was led by US Air Force Major General Michael Minihan, who is chief of staff for the Command that fought alongside South Korea's troops during the war.
The U.S. military also said that about 5,300 troops were lost during this war in what is now referred to as North Korea.
Forensic anthropologists have been examining the remains at a facility on Joint Base Pearl Harbor-Hickam, Reuters reported. One set was identified as a tall black American.
North Korea returned 55 boxes of remains as part of a denuclearization agreement reached between its leader Kim Jong-un and U.S. President Donald Trump at their Singapore summit in June.More news: SC governor issues evacuation for Grand Strand area

Between 1996 and 2005, the USA worked with North Korea and recovered around 400 caskets of remains, though Washington halted the cooperation in 2005 as it could not guarantee the safety of its personnel.

The July transfer coincided with the 65th anniversary of the 1953 armistice that ended fighting between North Korean and Chinese forces and South Korean and US -led forces under the U.N. Command.
The Pentagon has said it is considering the possibility of sending personnel to North Korea to search for more remains.
