The average per capita income in China is lower than countries like Costa Rica or Venezuela. It's less than half of what a minimum wage worker gets in the US. Every year, hundreds of thousands of people still die in China due to preventable diseases like tuberculosis and hepatitis. About half the children in the countryside are malnourished, to a degree that would not be conceivable for anybody in the US. This is the actual situation China is facing, and it's still dramatically better than many countries that were similarly poor decades ago.
In response to this, you and HN in general immediately react with fears of imminent Chinese world domination. Once again I ask you: why does the prospect of a few non-white people not starving to death make you so afraid? Why is this so alarming, so abnormal? I encourage you to spend at least a moment thinking about it.
