Sure if you water down the term of imperialism then yes. It is then incumbent on you to prove "imperialism" among the worst performers economically. What imperialism plagues liberia and ethiopia and honduras and papua new guinea
Papau New Guinea was ravaged by imperialism, invaded by imperial Japan and then was a meat grinder warfront in WWII. It was controlled by Australia since then.
Similarly in WWI, it was invaded by Australia and only gained independence in 1975.
Before that, it was split between Germany, the British and Dutch.
Before that, its population was impressed and blackbirded by European traders.
You asked what imperialism affected Papau New Guinea and I answered you. I'm not making an argument or addressing anything other than that from your post.
