The North Korean Embassy rented out its main building to the hotel company EGI GmbH, who operated the "City Hostel Berlin" in the building and thus generated foreign exchange for North Korea.[2] According to a UN resolution from 2016 (resolution 2270) it is prohibited to rent or lease North Korea any property. This is to prevent North Korea from generating foreign currency that the People's Republic could use to procure materials for its nuclear program.[3] Attempts by German authorities to take action against it had been unsuccessful until 2020, when it was closed.[2][4]
