Interesting piece over here on the eight democratic parties, the leftover of the United Front period in China prior to 1949, which are not only allowed to still hang around but granted an ornamental role in China’s constitution:
It was only after Deng Xiaoping came to power, and sought to restore the Communist Party’s tradition of accepting remonstrance, that the non-Communalist parties began to be taken seriously again. For instance, the leaders of the eight non-Communalist parties joined the National People's Congress and the CPPCC (Chinese Parliament), albeit their members only held honorary positions, not the real power that the first President of the Supreme Court held. Even so, the Communist Party has continued to show them great respect, as evidenced by their willingness to always discuss significant matters and consult with them.
Aside from the fact that the head of say, the remnants of the left Kuomintang hasn’t been given the post of deputy Prime Minister, I’d say this puts them on a level with the Lib Dems in the coalition. And of course, the LIb dems can propose legislation. But then, so can I, and members of the Left Kuomintang.
Even better, members of the eight parties are guaranteed posts in various state institutions, which makes them a pleasant option for people who don’t want to rub elbows with all the Rotary Club types in the actual Conservative Communist Party.
