A few months ago here in Zhuhai I met a guy who works for a UK vehicle conglomerate here in China that sells buses to Canada (Toronto if I recall). May have even been an international parent of the same group. Operations all over the world. IIRC they buy the chassis and bits out of China, and assemble in the US for Canada. He was explaining the chassis design for a Canadian bus is actually quite interesting. Due to the heavy use of salt on roads, it has to be quite expensively produced due to the speed of corrosion.
