I don't believe moving the plant was ever a real threat. Fuyao spent a large amount making the former GM Moraine Assembly plant into a world class glass manufacturing facility.

I worked for a competitor for many years, so I have some knowledge of the glass industry, but know little about that plant other than what I read.

Auto glass is very heavy and difficult to ship, so while sourcing it from Asia is always an option, it creates a lot more issues.
