A new report found "massive and expanding" links between major car companies and China's Xinjiang region.

"It is not impossible to audit one's supply chain to identify risks"The auto industry's supply chains are "closer to a ball of spaghetti than a linear chain," Simon Croom, professor of supply chain management at the University of San Diego, told Insider.
The average automaker may have links to as many as 18,000 suppliers, including their direct suppliers, the suppliers of those suppliers, and so on.
Per Croom, while many companies claim to lack full insight into their supply chains, "it is not impossible to audit one's supply chain to identify risks."
