Insider knowledge? Not really, unless you count asking actual chinese and taiwanese nationals what they think about it instead of assuming their world view is the same as my own.

Thanks for clarification. Do you believe nationals of these countries (or any country in the world) know what the CCP actually wants i.e. its true goals?

I think their true goals are pretty transparent, but the specifics of how they plan to achieve them are more secretive.

The CCP primarily wants to gain power. Political, economic, and social. The levels of ambition probably vary by individuals inside the party, but generally involves a uniform level of control across all regions of China (including Taiwan from their point of view), and enough global power to give them a free hand in East Asia.

Chinese nationals may put more emphasis on increasing prosperity. Taiwan nationals may put more emphasis on strict control and global power. Individual reactions largely vary. Out of both groups, limitations on personal liberties cause the harshest criticism of CCP, with the one child policy almost universally seen unfavorably.
