If anything, the Chinese government is not subtle. Here are a few floats from the 60th anniversary parade:
Xinjiang: Yup, that's an oil well and oil refinery riding up on top of a flying carpet. What else is Xinjiang good for? Delicious melons, of course. Docile Uyghurs are seen sitting down, sans knives or disease-filled syringes.
Tibet: The Han have broken through the Tibetan wall of feudalism with a shiny new train to Lhasa! Upwards, ho!
Tibet: And what's on top of that float? More docile ethnics in costumes. Notice the lack of monks.
