You'd be delusional to think that largest Chinese retailer has no foreign agent employees working there. Just like at any point time there's probably an Russian, Chinese and some other agent working at Apple, Google, Facebook, Amazon, MS, etc...
I specifically said dealextreme which isn't anywhere near being a "largest retailer". Also with Alibaba you can just message the seller directly. So I don't see how having foreign agents working at a place like Alibaba would help in the slightest.
Either way, like I said, I would be surprised if any agency was spending any effort tracking this, the devices themselves are often legal to own and the cases of abuses seem rare.
