You don't know your history. Birthrates collapsed in China because they made replacement fertility rates illegal, enforcement of which included the sterilisation of a hundred million Chinese women.
Because families were only allowed one child and they wanted their family names and legacy to live on, tens of thousands of Chinese girls were sent out for adoption to other countries or just aborted, until they had a male heir. Their male-to-female ratio is so skewed that it's physically impossible for all their men to get (exclusive) wives, so even bottom-of-the-barrel women are desirable, due to scarcity.
The effects of the one child policy are overstated. China's TFR was dropping before the one child policy, remained relatively stable for about a decade after it was implemented, and continued dropping even when the policy was relaxed.
And the reason for their birthrate collapse is the same as in the west. Too much female freedom.

That's not the cause of their current birthrate collapse however.
Mid chink women demanding a fucking house titled in her name before she'll even date you doesn't help.
