Right.
Some things are easy to keep track of and some are harder to keep track of. We have some mechanisms that have been developed with regard to diamonds, for example, to ensure they are not conflict diamonds. One of the most obvious is that Canadian diamonds are incised with a laser so we know where they come from. My wife insisted when I proposed to her that I do so with a Canadian diamond.
Gold and any mineral of that sort that is fungible, in a sense, strike me as being very hard to trace, while things like textiles are some kind of intermediate case.
Are there any thoughts on how one can actually keep track of the hard to trace stuff and therefore eliminate the child labour practices we're trying to deal with?
