Nantes, France's Château des ducs de Bretagne museum of history delayed its exhibition about Genghis Khan after the Chinese government insisted that the words "Genghis Khan" not appear anywhere in the show. Same goes for "Empire" and "Mongol." From The Guardian:
The exhibit was planned in collaboration with the Inner Mongolia Museum in Hohhot, China. But tensions arose, the Nantes museum said, when the Chinese Bureau of Cultural Heritage pressured the museum for changes to the original plan, "including notably elements of biased rewriting of Mongol culture in favour of a new national narrative".
The museum branded it "censorship" and said it underlined a "hardening … of the position of the Chinese government against the Mongolian minority".
