It does with Volvo, although I couldn't say how big it is relative to global industry. Within Europe it's a large player

Volvo is complicated. Basically a lot of these smaller companies and countries realized there was no way they could make the economics work with the cost of electronics and software-related R&D being what they are. So they sold to larger players. But design and final assembly still happens in Gothenburg for high-end models that are typically destined for the EU market. The US now manufactures the SUVs.

Scania is Swedish, too.

A Chinese company owns Volvo since 2010 or so.
