Benjwong: Please look into the various news sources. The tainted milk had passed the protein test and Sanlu became aware of the melamine in early August, one week before the Olympics! It's more than reasonable for anyone who knows China to assume that they want to suppress the news at that time (and now we have sources). I've seen reports that Sanlu recalled their products by their own efforts (not publicity, not government) weeks ahead of the news breaking out. Today's news claims the last straw (in suppressing the news) was the NZ government directly talking to PRC government last week.
