Imperialism: The practice of states to expand their influence beyond their sovereign borders.

Burkina Faso is imperialist for kicking France out of the surrounding region, excellent definition.

State-Capitalism: The mode of production where the means of production are owned by the institutions of the state.

Referring to publicly owned, planned economies as "state capitalism" is monstrously misleading. Capitalism is a system of private ownership, marketized distribution, with capital accumulation as the primary goal of capitalists. Using "capitalism" to refer to an administered, planned economy is just a subjectivist argument. State capitalism is a better descriptor for the Republic of Korea and Singapore, capitalist economies with heavy bourgeois state control.

So, now you want a moralist argument? O.o

This isn't a moralist argument, the argument is to get you to actually explain with concrete examples how China is imperialist. Given that you provided a definition of imperialism that makes Cuba imperialist for exporting doctors and aid missions in order to gain favor with surrounding countries, I don't think it's necessary to provide any examples of "Chinese imperialism."
