Badge engineered Taiwanese Chevrolet Colorado?

don't you mean Russian Chevrolet Colorado?

I'm actually correcting myself with this statement, but...

Thai-built Colorado, actually. It's a Russian-built version of the Chevrolet Colorado, which is built and sold in Thailand (also sold in Australia as a Holden), not to be confused with the North American version of the Colorado.

Not a rebadged Great Wall pick up or something?

Nope...

This is a Thailand market Colorado Double cab, the exact vehicle this is based on, pre-facelift.

The foreign market Colorado was refreshed in 2007-08, I think. This is essentially a continued production version, in a different country. Kinda like the Sens is a continued production Daewoo Lanos.
