BCI Bus is an Australian company that manufactures buses in China using both Chinese and Australian components. Now whilst this is not a Chinese company, there are many manufacturers outside of China that have joint ventures and production facilities in China. The main manufacturing facility is in Nanchang which, and I might not be 100% correct, is where Bonluck Bus is based.

You've probably realised this yourself by now, but these are Bonluck models (http://www.chinacarforums.com/forum/showthread.php?t=6470). In particular, the BCI 6120 is the same as the Bonluck JXK6120BCF.

Yes, I have realised it. But it said on the BCI website that these were made with Australian parts.

Maybe BCI is owned by Bonluck Bus.
