Well, Just got my C7 on Thursday. Haven't had time to look over it too much. But, there is a nice "Made in China" label in the handbooks leather pouch, and the Corvette logo'd "Battery Protection Package" option charger/conditioner is also made in China. That comes with a 2 pin European plug on the end. Ian Allan don't give you an adaptor, and expect you to get one from your local electrical shop!!! Done that, and that's made in China too.
Then again, seem to remember that the wheels on my '85 C4 were made by Enkei (a Japanese company?)
