China is definitely not communist, but it is definitely less capitalist than the US. Fundamentally the "Communist" Party is about control, which is directly opposed to a free market (i.e., capitalism). For example, the Chinese government wants a stock market. But, they want this market to always go up. (down = people lose money = risk of social unrest) So this year they tried stopping the market if it fell too far, suspending trading of certain companies, telling fund and/or brokerages that they could not sell certain companies. NOT capitalism. Also, the economy is dominated by large state-owned-enterprises (SOEs) which receive strong direction from the government. The government tells factories around Beijing to close whenever a government meeting is in town, so the air will be clean. Note how none of those things happen in the US.

>>China is more Capitalism than USA.

China is not at all capitalist as there is no free market, and you may say it's not communist/marxist if it pleases you but it's a communist party controlled tyranny. *

If anything, China is much, much more tyrannical and dictatorial than USA. Tyranny and brutal dictatorships is only what communism/Marxism have produced in large amounts. The communism/Marxism have produced very little good and very large evil wherever they got foothold.

* A Chinese citizen cannot even move within China without getting permits from the communist politburo approved officials, forget about him/her being able to launch a business freely.

Edit: added * details

Communism/Marxism =/= tyranny and brutal dictatorships. They aren't mutually exclusive, but one doesn't imply the other. There was Marxism and tyranny in the Soviet Union, modern China only has tyranny.
