Putting Chinese and Japanese (I guess because their
writing systems are kind of similar) is similar to,
similar to saying the same for English and Basque (which,
like Japanese is agglutinative) because they both use the
Latin alphabet.
This comparison is flawed. The Latin alphabet is phonetic and carries no inherent meaning, while the Chinese Hanzi (which were, historically, adapted in Japan and slightly modified/simplified since then, and are called Kanji there) rely on meaning, and each character can have multiple ways to be pronounced.
I also find it highly ridiculous that politicians (at least here in Germany) still spout crap about "international, millions of dollar heavy child porn rings" or similar nonsense.
I'd wager[1] that most child pornography is either a) documented domestic abuse of children by relatives or b) jailbait (ie, suggestive or explicit pictures of legally underage, but physically mature persons).
For the former, we're fighting a symptom. As I said, we need to fight the cause, child abuse. But there's a problem with that: it's a long term process, and a difficult one at that. Demanding the takedown of websites with child pornography works way better to get yourself elected.
For the latter, I'd go as far as to ask the following: who is hurt by people with a paraphilia involving underage persons[2] masturbating to images? Especially if those images were made in consent with or even by the person depicted?
[1] This is another thing about the entire child porn discussion: you can't confirm anything without getting yourself in all sorts of legal trouble. There was a good example of this here in Germany a while back, see https://en.wikipedia.org/wiki/Joerg_Tauss
[2] I'm putting it this way because Pedophilia isn't the only such paraphilia, even though the term is often used to mean "attracted to underage persons", which is very wrong.
