Kim Jong-un is trying to boost North Korea’s cattle stocks by procuring bull semen on the black market from Denmark.
The North Korean dictator wanted to find the exotic product and sneak it into the hermit state, according to Danish filmmaker Mads Brugger.
Mads has produced a documentary called The Mole in which he goes undercover to investigate who North Korea tries to flout trade sanctions.
He claims a North Korean diplomat in Sweden, named only as Mr Ri, asked spies to help him obtain a variety back of bovine sperm.
Mads said: “Mr Ri, the secretary of the embassy in Stockholm, wants the mole to acquire samples of Danish beef cattle semen from various breeds, the right containers for transportation and then get it to the embassy in Stockholm (so he could) take care of getting it to Pyongyang.
“It was an absurd discussion. It’s not in the film because people would definitely think that it has to be fiction.”
The documentary-maker is prepared to hand his findings on the breach of sanctions to the UN, but North Korea blasted the contents of the film as “pure fabrication”.
Hugh Griffiths, who was co-ordinator of the UN Panel of Experts on North Korea between 2014 and 2019, called the revelations in the film “highly credible”.
He said: “This film is the most severe embarrassment to Chairman Kim Jong-un that we have ever seen.
“Just because it appears amateurish does not mean the intent to sell and gain foreign currency revenue is not there.
“Elements of the film really do correspond with what we already know.”
Mads said he orchestrated a three-year sting operation to reveal how North Korea flouts international law.
North Korea has been under sanctions from the UN due to its ever-expanding nuclear programme.
Earlier in October Kim unveiled what is believed to be one of the largest intercontinental missiles in the world.
Initially, sanctions were focused on trade bans on weapons-related materials and goods but were then expanded to include luxury goods to target the elites.
Kim is under pressure with the North Korean economy struggling and millions living in abject poverty.
In a military parade earlier this month, Kim cried at a public appearance as he admitted his failings to dealing with the coronavirus crisis.
But some analysts think this could be a ploy to portray himself as a man of the people.
