Eh, I don't agree with this. The issue in your case was that someone didn't properly secure a piece of scrap metal to their vehicle. The fact that China demands scrap metal doesn't seem relevant to me given that this sounds like simple incompetence.

You wouldn't blame the automaker for a drinking and driving incident that resulted in a death, you'd blame the driver.

Curious why China is named

There's a lot of cheap money floating around in China as well. This is funding business models like that of Ninebot, who is the manufacturer for a lot of these cheap scooters. Another Chinese company that had a similar business model is Ofo, which essentially went bankrupt a few months ago after raising over $2B in funding for dockless bikesharing.
