No, it smells too much of ethnic nationalism to me. As long as the artefact is maintained in a professional and respectful manner, it really doesn't matter where it is.
You could say that taking the Elgin marbles was wrong, but what if the Greeks stole foreign resources to create them? I'm not saying they did do that, but the point is that history and 'heritage' is a very fluid thing. Also, the boom era of excavation is a part of history which should be rembered; the fact that the Elgin marbles are in a British museum is almost an artefact in itself.
