Historically, Disney has never done well with racial stereotypes. What may have seemed like light-hearted fun at the time becomes unacceptable when viewed in a modern context, and the character of Shun Gon in 'The Aristocats' is one of the worst examples.
In his biggest scene, Shun Gon plays the piano with chopsticks and sings in a faux-Asian accent about fortune cookies. Throw in his prominent buck teeth, and you've got an extremely crude Oriental caricature. A gong is struck when he's singing, just in case you didn't get the message.
