While I agree copying is highly unethical, in this particular example the Chinese government can't do much, as the iPhone 6 is not even announced yet. Goophone might even be in the position to sue Apple for copying, when the mockups turn out to be correct
Back when the iPhone 5 came out, Goophone publicly threatened to prevent Apple from importing it into China. AKAIK, nothing came of it.
Here is Goophone's official video about it back then. The goofy translation is humorous as well:
Legally, they had the right. You see, China has the same Design Patent rules as the new ones the US just passed. That is, a patent goes to the First-to-File, not the First-to-Invent.
Therefore if Goophone files a design patent for something that looks like the iPhone 6, then legally they can sue Apple. OTOH, China courts generally find defendents not guilty if there's any kind of difference, which there would be.
It's ironic that big companies like Apple pushed for First-to-File, because they can afford to do that constantly, giving them an advantage over smaller and home inventors who used to rely on First-to-Invent. However, First-to-File can obviously backfire.
