The interaction between the two countries took place at the US airbase in South Korea, where soldiers formed an honour guard after the plane carrying the remains touched down.

Earlier in the day, US President Donald Trump thanked North Korean leader Kim Jong-un for the diplomacy.

"The Remains of American Servicemen will soon be leaving North Korea and heading to the United States! After so many years, this will be a great moment for so many families. Thank you to Kim Jong Un," Trump tweeted.

North Korea and the USA had agreed the repatriation during the June 12 meeting between Kim Jong-un and Donald Trump, heads of the respective countries.

Reports said that 55 soldiers have been returned to the US by North Korea. The remains will now undergo forensic tests to determine whether they were actually slain during the war or not.

The said tests could take years.

Earlier this month, US President Donald Trump tweeted to say that he was happy with North Korea's dedication towards the denuclearisation of the Korean Peninsula.

The reaction came after US watchdogs, analysing satellite images, said that North Korea was dismantling a key rocket launching site, thus, keeping its end of the bargain.

A Rocket has not been launched by North Korea in 9 months. Likewise, no Nuclear Tests. Japan is happy, all of Asia is happy. But the Fake News is saying, without ever asking me (always anonymous sources), that I am angry because it is not going fast enough. Wrong, very happy!"

Trump had also said that he will not be rushing North Korean leader Kim Jong-un to denuclearise the Korean Peninsula.

"We have no time limit. We have no speed limit. Discussions are ongoing, and they're going very, very well," he was quoted in the media as saying 

However, despite all the positive reports regarding North Korea's nuclear tests (or the lack of it), reports have emerged that the country is still secretly upgrading its nuclear enrichment sites.

A report earlier this month stated that Pyongyang is bolstering its official nuclear enrichment site at Yongbyon, simultaneously, it's investing in another two secret sites.

The reports, still unverified, have been deemed accurate by watchdogs.
