I can easily imagine that chinese companies now want to export their tech, including surveillance tech, to other countries and that they're lobbying for it.
Glad it was withdrawn that easily.
Serbia is definitely becoming a Chinese colony. China is placing dirty industries here, effectively cutting transportation costs to the EU and reducing pollution in China. Also, a few years ago there were official government proposals (like this) to bring Chinese police to Serbia.
Unfortunately, the EU absolutely doesn't care about any of this and actively supports the Vucic regime.
And I wouldn’t stop there. Why wouldn’t China want to profit from the surveillance of others as well? It would give them an edge, at least ostensibly, and a way to keep spreading their tentacles and to displace the American empire.
