I think Choice is to some extent barking up the wrong tree by applying the same standards to retailers & manufacturers - while (say) Hasbro has a great deal of control over manufacturing methods, (say) Target buys the toys from the manufacturer - a better measure of Target's performance would be its employment practices. It's not in a position to know what standards/conditions are like in the country of manufacture, compared to the manufacturer.
On a related note, with many of the manufacturers, the policies would be set by the overseas head offices (as they mentioned with TY), and in many cases their Australian presence would be little more than a supporting branch office.
Having said that, it's pleasing to see that Hasbro do take the matter seriously - even if they're not perfect. It's interesting (and saddening) to see that Mattel failed to respond, despite all the negative PR they received from their lead paint fiasco. Clearly Hasbro take this sort of thing far more seriously than Mattel do.
