A year-long BBC Eye investigation has uncovered that Chinese tomato paste produced using forced labour in Xinjiang is likely to be being sold in major UK and German supermarkets. Runako Celina has teamed up with Pulitzer-prize winning journalist Alison Killing to find out the nature and scale of forced labour in the tomato fields of Xinjiang, and follow a trail that shows the resulting puree might be ending up on European shelves. Using satellite imagery and shipping data, they track the route the tomato paste takes from Xinjiang to Europe, where they uncover evidence showing there’s a strong likelihood it is being sold on to some supermarkets. The supermarkets all said they took the allegations very seriously. But they disputed the BBC’s findings.
