China's one child policy has had debatable effect and a number of unintended side effects. If China wants smart people to reproduce more, then skewing the population towards a male majority is only going to work through repression of large numbers of men who no longer have hopes of reproducing.

The traditional solution to large numbers of young men without mates is not repression (that hardly works, they'll rather run revolutions) - it's simply to pack them in colorful uniforms and march them to the neighboring tribe to look for mates and loot or die trying, both options "solve" the problem.

Compulsory military service is often defacto slavery. It's an even more insidious form of repression. And if the populace is manipulated into wanting to go to war, that's worse.
