Why is Chinese supremacy so infallible?

Simple..  we're the largest ethnic group in the world and one of the fastest growing economies.  Fast economic growth + already dominant population = WIN.

I like how efficient they are at carrying out their executions. Xan Wi Yun decides he wants to be a pornographer or criticize the Government? He's getting a mobile death van coming to his area.

Who wouldn't like the idea that their Government has developed vans made for the specific purpose of carrying out lethal injections to kill pornographers and other thought criminals and then sell their organs to western nobles?
