Is imperialism still a useful concept? Why and where?

What countries does it apply to - does it still make sense?
Is it wrong to talk about ongoing Brazilian imperialism or Chinese imperialism or Japanese imperialism in 2013?

Imperialism has been subsumed, we have capitalism now. It remains an element though, I guess.
