The CBC has done investigative journalism to trace global tomato paste supply chains back to Xinjiang, which is....the world's largest exporter of tomato paste.

But, Zenz then asserts that tomato production uses slave labour, so supporting buying from Xinjiang is bad actually.

Another nugget, that when CBC went undercover to try to buy tomatoes and ask about forced labour the suppliers seemed to have no idea what they're talking about.

Also, the official China statement on Uighur tomato harvesting is to create economic opportunity for the residents - so even on its face it is better than the temporary migrant labour that Canada imports to harvest its food, and at worst it's equal.

This is all coming on the recent news that China is dismantling a number of the reeducation centres in Xinjiang. How could China do this?
