The party's central committee, which consists of 2,300 delegates from 96 million party members out of a population of 140 million, elects the Politburo which in turn appoints the Party Chairman, who is the party leader and the ruler known to the outside world as the Chinese President. The Chairman is the one who rules the country at his will, and the approval of the party normally follows although in theory the decisions are taken collectively; that is the Chinese system.
