As has already been mentioned, you can't. What you can do, however, is to check the listings carefully if you're considering making a purchase. If the seller is a business seller then scroll right down to the bottom of the page and check out the seller's business information. If the address given is based somewhere such as Hong Kong or Shanghai then don't commit to buying from that seller and check out some of the alternatives on the search results to see if you can find an identical item being sold by a seller who isn't based in China.
