Wow, I thought you were making that up. It’s real. Why not just repeal the child limitations then? No reason to keep them in place if the rate is that low.
They did repel them, twice (once to put the limit to 2, now it's 3).
They also forcibly 'immigrate' SEA women since 2010[0], forming a combo with the Gulf countries : the Gulf enslave the men under false promises, then cartels raid villages, capture and sell the women (Vietnam is the only country where the state is strong enough to limit that). Sadly is hard to investigate the issue correctly, given China's lack of transparency, but it is possible that despite relatively closed borders, China now lead the world in sex trafficking, overtaking the Magreb (morroco to lybia).
Chinese, especially in the upper tier cities, don't want babies now. Same as the West and for roughly the same reasons. Historically kids stayed with their parents until marriage who would then look after the grandchildren while they work. Now the parents are getting left behind in the villages or low tier cities while the kids fly out to the higher tier cities to work leaving no childcare structure and everyone grinding away at work with no time to find partners.
