The power of the Communist Party depends on the Party members being loyal to the Party, and working hard to maintain Party control over the country. This is incompatible with a free market system.
In a free market system, you have business owners who have the money to buy loyalty to themselves from the low-level Party members.
China is in a transition from communism to corrupt oligarchy, in which all communist party members can leech on business and get themselves fabulously rich. The golden parachute for entire Chicom hierarchy.
Some American business or individuals love to be part of this new oligarchy, which they think would last long, but won't.
