For five years, Hugh Griffiths was part of the UN expert team investigating North Korea's violations of international sanctions, and as recently as a month ago he stated in a report that the dictatorship was doing or attempting to do arms deals with some 30 states and armed groups.
The country's embassies are the logistics center for the shops, says Griffiths.
He is not surprised by the information that appears in the new documentary "Mole - Undercover in North Korea" which is broadcast on SVT Play.
The documentary reveals that North Korea's mission in Sweden functioned as a liaison center around a secret arms deal.
- We do not have previously documented cases of or attempts at sanctions through the embassy in Stockholm, but we have a dozen cases in other places in the world where North Korean embassies are involved in sanctions and played a major role.
Risk that North Korea will start selling to terrorist groups
Hugh Griffiths believes that the information in the documentary Mullvaden is astonishing and worrying as the North Koreans do not seem to care who they sell to.
- Individuals with feelings can go to Pyongyang and be offered ballistic missile technology.
It's not good, it's dangerous.
- This is one of the reasons why the Security Council has introduced sanctions against North Korea, because North Korea sells its ballistic missile technology to countries such as Syria and Iran.
Secret price lists
According to Griffiths, one of the most interesting pieces of information in the documentary is the secret price lists.
- We have never seen any price lists before, says Hugh Griffiths.
- For 5 - 20 million US dollars, you can buy 1-5 different models of scudrobots.
Who knows what will happen if they start making such offers for weapons of mass destruction.
