LOL. As if the Constitution of any tyranny has ever meant a thing in practice. The USSR and most other commie countries had quite lovely constitutions. It's just that they were never more than window-dressing.
If the Chinese truly meant to renounce socialism, surely they would’ve changed their constitution to match that. Red China is of course still a one-party state. The constitution is basically a reworking of the Soviet constitution, with all the supposed “rights” granted to the people (except for really important privileges like habeas corpus). The stronger Red China gets economically, the more it will be able to switch over to these socialistic goals in earnest; pandering to foreign corporations is a means to this end. Like the Soviet NEP.
