The thing is, the bulk of child porn is consumed in the US and produced in Japan and the Philippines. China culturally does not sexualize children. Neither did Japan, actually, until the anime and rorikon (lolita obsession) kicked in. This is a relatively recent social phenomenon. The US soldiers stationed in the Philippines are the biggest consumer of, not child porn, but child prostitution.
I researched this extensively when I vacationed in the Philippines and Thailand. I was appalled by the treatment of women and the condition of children there. Thailand was much better in comparison, but they have the issue of "transgender freak show". Boys of poor families are being sold off to be neutered and end up in circuses as ladyboys. those ladyboys don't just show you their bits and what they got and entertain you. They do things that are truly damaging to their bodies. Therefore, they only live a very short life. For example, things they inject to keep them look a certain way, and when they do their freak show, think about stainless steel ping-pong balls coming out of places that are not supposed to host 8 ping-pong balls. I will leave you to imaging the rest, and the type of freak show they do.
Edit:
To clarify, lolita is generally regarded as around 14 years old girls. Rorikon is much younger, around preteen girls.
