Imperialism is actually when you are the victim of imperialism, checkmate tankies. The real imperialists are the country that avoid projecting power outside their own border and hasn't gone to war since the 80s, not the one with hundred of military bases around the world that they use to violently enforce their global hegemony.

Imperialism is when you have a civil war.
Liberals always think "imperialism" is when you say things about places you don't directly rule. I am begging you to learn about unequal exchange and foreign interference. Imperialism is a process of incredible violence where labor and resources are extracted, finished products are sold back at a high price, and governments who resist are interfered with. Imperialism is enforced by organizations such as the IMF, CIA, and US Military.
If China were like American imperialists, Taiwan would have been reduced to rubble long ago. A better example of imperialism would be the attempt America has been discussing to steal Taiwan's semiconductor manufacturing industry.
