How unstartling, en.Wikipedia still has cross-namespace redirects. Empress of China should be a disambiguation page: of course there have been many Empresses of China, but this was also the name of at least one locomotive engine and several sailing vessels including the historically significant Empress of China owned by Robert Morris which was the first United States vessel to visit China, and thus established both diplomatic and commercial links between the countries. It was so significant a voyage that the current government of China still refers to the ship in official speeches.[1]

But en.wp redirects everything to the category Chinese Empresses.
