I don't know if I've ever heard anyone use the term "concentration camp" without qualifiers to refer to anything else than the nazi concentration camps (or something equivalent).
Maybe it's just me, but I think it would have been more clear if you said internment camp if your intent was to refer to the broader context and not invoke a comparison to nazis.
