This is an indication that Russia has lost its earlier status in NK.
The question is: what has China promised?
... and now they are very open with the bad situation in NK:
Translation from Russian:
The locks on the gates of the missions of Great Britain, Venezuela, Brazil, Germany, Italy, Nigeria, Pakistan, Poland, Czech Republic, Sweden, Switzerland, France have already been hung, all foreign personnel of international humanitarian organizations have left. Only 9 ambassadors and four chargé d’affaires currently represent their states here, and the staff of most of the embassies still functioning here has been reduced to a minimum.
Meanwhile, over the building of the Russian diplomatic mission in the very center of Pyongyang, the white-blue-red tricolor is still proudly fluttering. Of course, we also have a hard time, there are a lot of problems, several families were forced to interrupt business trips for various reasons. But the working capacity of the team is fully preserved, we are performing and will continue to perform all the functions assigned to us. The Motherland can rely on us!

The little Kim will not be pleased.
