I am talking about the digital camo, as far as I know, China's potential adversaries do not use digital camo on vehicles.
At that distance you do not see camo , it more a silhouette against the ground, the shape has more to do with how the tanker going to see the target then the camo.
I can also point you to read why a lot of tanks usually doesn't even have a camo , just green-ish paint.
Cause when they studied the effectiveness of camo for helping the tank to hide during WW2 , the conclusion that it had minimal effect , it is mainly effective against air reconnaissance.
So you will see that no Allied nation use one cause they dominated the air after 1943, but the German army did use camo.
Fast forward 80 years later ,they kept the tradition. The Germans still paint camos on their tanks , but US UK Russia doesn't.
These day , with night vision , and thermal sights , camo is even less relevant for hiding a tank , so it just an ascetics thing.
China , Japan , Korean has camo for tank , I think it does look better with some camo , but it has no real affect for concealment against modern electronics.
