Even the name - Cathay. It harks back to a quaint time when Britain was the world superpower. What relevance has the name 'Cathay' to the modern Chinese? Nothing, but a loathsome reminder of the time when China was on its knees before the europeans.
Actually, Wiki indicates the term Cathay was coined sometime between 900AD and the 1600's, long before the Europeans did anything nasty other than trading, and for much of that period China was the world's biggest economy.
Marco Polo took spaghetti down the Silk Road, and that went down very well.
