That word, I don't think it means what you think it means.
Recently I saw the decision by China to sell less rare earth elements described as imperialism. I'm sorry, but that's not even close. Going to China with a flotilla of gunships and forcing them to sell you their stuff in return for smack is imperialism. Choosing not to sell your own stuff to other countries is not imperialism. The lack of any attempt to extend rule over another country is a bit of a give away that imperialism isn't going on, as is the lack of violence, threats of violence, or even the bribing of corrupt officials. (Pssssst! Hey, I'll give you 10,000 Euros if you promise not to buy our stuff, okay?)
