Does plantation have a negative context outside the US?
In the United States, the word plantation almost always conjures up images of Southern slave plantations (sorry, Rhode Island). Is a similarly-negative context associated with the word in other English-speaking countries or places? I know it is sometimes used in writings about Vietnam, does it have a negative history there as well?
In Britain and, I suspect, The Commonwealth more widely, along with a present -- but less prominent -- association with the antebellum South, the word reminds the reader of the British Empire which, -- being an Empire -- had its own arrogant excesses.
However, in Britain at least the word plantation is widely used -- apparently neutrally -- to describe, for example, tea, coffee, banana, and rubber farms planted in tropical places: after all, it accurately describes them.
However, you are increasingly likely to hear the word "farm" used in its place (for example in advertisements), I suspect for this reason.
Evaluation of the moral legacy of the British Empire and American slavery is incredibly important, but is an issue which is not really on-topic here.
However, if your context is such that your text must be sensitive to issues of colonialism or slavery, I suspect you cannot wield the word plantation carelessly anywhere in the English-speaking world.
as far as I know the word plantation does not in other English speaking countries besides UK such as Kenya, India and Sri Lanka conjures up images of Southern slave plantations as well in other countries were English is widely spoken.
