That might be true, but the tiger meat must have been smuggled into China from other countries. I believe today you still can find tiger meat in Guangdong if you try really hard and are willing to take the risk of staying in jail for a few years and pay $5000 in fine.
Actually, if you go back and read the news item, it was stated that the animal "had died in a fight with other tigers in a zoo in Shanghai". How true that is would be anyone's guess..
