China has been ruled by engineers since Deng Xiaping died.
Basically, from 1949 - 1976, China was ruled by Mao, various other old school communists revolutionaries and some glorified warlords who hitched their wagon to the communist horse at the right time. From 1977-1992, China was ruled by Deng, who was also an old communist revolutionary, but who trusted and relied on engineers more than communist ideologues. From 1992 on wards, China has been ruled almost entirely by engineers, although there is a slight trend to promote more economists and social scientists to the top spot in the last leadership transition.
