Is Harbin Siberian Tiger Park ethical?

Hi, I've been looking into going to the park and I've read some good and some bad things about it. Tour Beijing claims that the park does "breeding, scientific research, protection, training as well as sightseeing." But I have read some articles about the park just being used to breed tigers for the meat and bones. Supposedly even selling "Tiger Liquor".

I was just wondering if you could clarify the purpose of the park. I'd love to go but I'm concerned about what I have read.
