Difficult to distinguish between actual slave labour and China-is-bad propaganda.
Harm to the end user: none^
Benefits to the end user: more affordable tomato paste
Government action to prevent slave labour products entering Australia: none^
^close enough.
Negatives to end user: unknown pesticides or banned pesticides.
No propaganda - lack of validation, evidence and trust
It is perfectly legal to sell Chinese tomatoes in Australia (which is not necessarily a good thing, re: forced labour in Italy and China). The fraud is mislabeling them as Australian or similar, denying consumers from making their own ethical choice. Which is your harm to the end user and generally enforced by the ACCC.
