The Chinese Co-Prosperity Sphere that entered space and then the stars was blessed with a ready supply of compliant lesser races they could send out to claim the wild frontiers. They moved entire populations off Earth to settle far off worlds and the true Chinese expanded into the empty lands. They built their greater Hegemony in the stars on the backs of the riffraff they didn’t want. It was an elegant way to dispose of the excess population while turning their corner of Earth into a paradise for the true Chinese people. China became the Middle Kingdom once more, masters of all the corners of Earth that mattered, and wealth flowed to Earth from the far off colonies. It was a Golden Age for China. One they planned to maintain forever.
