Is China supplying weapons to Serbia?
Serbia is pro-Russia ?
Serbia is probably traditionally the most pro-Russian EU state. At the moment, it's Hungary, but that's more related to Urban.
Seems like the planes were flying over NATO airspace that includes Turkey and Bulgaria. That Stolenberg guy will be very unhappy over it. Wonder what leverage China has over Bulgaria.
I'm not sure how they can stop it since it's just a standard cargo operation.
