SVT Nyheter has sought Foreign Minister Ann Linde in connection with North Korea's secret oil, drug and arms deals, which are revealed in the documentary.

However, Linde does not want to comment on the information in "Mullvaden" but refers to the Ministry for Foreign Affairs.

It is taking a serious look at how the North Korean regime is working to circumvent the UN's increasingly harsh sanctions, and according to press communicator Erik Karlsson, they are now working to analyze the information that emerges.

- It is of great importance that the UN sanctions are implemented and this is also what North Korea is obliged to do, says Erik Karlsson to SVT News.

"Does not go into details"

How do you see that the North Korean embassy in Stockholm has been used to conduct business?

- In general, it can be said that people with diplomatic immunity in Sweden are obliged to respect Swedish law.

The Ministry of Foreign Affairs acts on information from, among others, the police and prosecutors in case of suspicion of crime by persons with diplomatic immunity and addresses the case with the embassy concerned.

- What measures are taken depends on the severity of the issue and we do not go into details about specific cases.

"North Korea obliges to implement UN sanctions"

Have you had any contact with the North Korean embassy due to what appears in the documentary?

- We have an ongoing dialogue with North Korean authorities, but I can not go into detail in the talks we have with other states.

But at an overall level, of course, North Korea is obliged to implement UN sanctions.

What do you think about the information revealed in "The Mole", does it come as a surprise?

- As I said, we take the information that appears in the documentary seriously and we now need to analyze them carefully to see what they can mean.
