That's because Chinese copyright infringement is mostly internal. You don't see sites protected by China distributing copyrighted content to the rest of the world.

Smart move, that's necessary lip service to IP treaties. One can extrapolate however, just about every device or widget I buy these days is made in China. What's noticeable is that many, many of them are identical to items that were once produced in the US, UK or Europe (I'm old enough to remember many of those original Western-made products).

Presumably, these items can now flood Western and other markets because they're out of patent and or the original manufacturer has gone bust, not so copyright/IP due to its long expiry date.
