There's even a case that Ketchup is a distant relative, as it started out as South East Asian oyster sauce, was imported to Europe, turned into fermented mushroom sauce, was exported to the colonies, and finally turned into tomato sauce (though originally sometimes with fish in it).

There's speculation that Asian fish sauce came from Greece through the same cultural diffusion processes that brought Greco-Buddhist sculpture as far as Japan.
