USA military officials met with their North Korean counterparts Sunday to discuss the repatriation of the remains of soldiers left after the Korean War ended in 1953.
Pompeo initially said the two sides had agreed to hold talks on USA remains on Thursday but no North Korean representatives showed up at the border.
However, the possibility still stands that North Korea may request certain actions in return, or call for a follow-up general-level meeting to discuss issues surrounding the Armistice regime.
The North's proposal of talks with the UN Command, even though the UN Command is led by the U.S., was seen as an attempt to use the meeting to discuss not only the repatriation of war remains, but also other issues, such as a proposal to jointly declare an end to the 1950-1953 Korean War.
This meeting was the first between the UNC and the North Korea's military in nine years and four months. The U.S. team would then fly out with the remains on July 27, either to Osan Air Base in South Korea or to Hawaii.
Monday's meeting was a follow-up to a general-level meeting held on Sunday, . which U.S. Secretary of State Mike Pompeo described as "productive and cooperative".
"I firmly believe that the strong will, honest efforts and unique approach of myself and Your Excellency Mr. President aimed at opening up a new future between the DPRK and the USA will surely come to fruition", the letter reads.
More than a month has passed since the historic summit between the leaders of the United States and North Korea.

The State Department confirmed that talks resumed Monday in Panmunjom "to continue coordination on the transfer of remains already collected in (North Korea) and the re-commencing of field operations", but declined to provide more details.
He first announced that talks about the issue would begin after a trip to Pyongyang earlier this month.
About 7,700 U.S. soldiers are listed as missing from the Korean War, and 5,300 of the missing are believed to be in North Korea.
"We understand that the North-US talks on repatriation of the remains are under way", it quoted an unnamed official as saying.
"The North Koreans put a lot of weight on rank and status", said Robert Kelly, a political scientist at South Korea's Pusan National University.
North Korea "will take practical measures to help the released people settle down to normal working life", KCNA said.
Richard Downes, executive director of the Coalition of Families of Korean & Cold War POW/MIAs, said recently that he had been told the North may have the remains of more than 200 American service members that were likely recovered from land during farming or construction.
