I could not believe it last week when I was going to buy a package of frozen perch and I always look to see where it was packaged. Guess what...It was processed in China...I left the fish in the store.
Before you buy something, look to see where it's made. If it carries the Made In China label, put it back on the shelf. Doesn't matter if they're in the WTO or not. No one can force you to buy their stuff. (Probably means there's no reason to go into Walmart at all.)
