The Chinese government says the Lop County Hair Product Industrial Park in the country's northwest is a place where people make wigs and other hair products that get shipped across the globe.

Others say what's happening at the park is forced labour, and that it's just the latest in a pattern of grave human rights abuses committed in recent years against the country's Uighur Muslim population — including the use of detention camps, mass surveillance and even forced sterilization.

The Lop County Hair Product Industrial Park in Xinjiang province is an incredibly secretive, highly guarded place, yet Globe and Mail journalist Nathan VanderKlippe managed to travel there. Today on Front Burner, VanderKlippe discusses what he saw.
