After the readmission of the diplomatic bilateral relations between North Korea and Germany, like Germany did in Pyongyang, North Korea also moved back to their old embassy building in Berlin which they used at the time when Germany was still divided.
The former ambassador of North Korea, Hong Chang-il, was replaced by the current ambassador Hong Ri-si in 2011.

The once entirely occupied building for the North Korean representatives is only partly used for the embassy.
The official building moved to the Glinkastrasse 5-7 in Berlin, so the other parts of this building nowadays are used among other things as a hostel for tourists.
Germany threatened to shut down the hostel, in order to curb Pyongyang's nuclear weapons capability in May 2017.
