First of all, I don't necessarily agree with the statistics that all of it comes from that particular origin. Beyond that, I think the number one way to get the attention of the U.S. government is through the total lack of transparency. In other words, if there's an opportunity, especially after 9/11, for billions of dollars to be allowed through the monetary system unaccounted for, that's something they're interested in.
The manufacturers that may choose to send product through that avenue are saying the product is for export and therefore it does not concern the U.S. government. Maybe there's some merit to their argument.
But the fact that the financial traceability of those activities is not transparent is a very good way to approach that avenue, as far as I'm concerned.
