What are good gifts to bring Chinese acquaintances from America?

Chocolate is a hit, Chinese chocolate is comparatively of lower quality, consider See's Candies which is truly American and really yummy. Other US food items Chinese people appreciate include beef jerky, pistachio, macadamia nuts, Wisconsin ginseng (this is totally different from Chinese ginseng and only grown in Wisconsin). Remember you can only bring 2 liters of alcohol into China duty free, and most Chinese people appreciate French wine and cognac more than American. Anything stamped or marked as "Made in USA", "France", "Italy", "England", "Germany", "Japan" is good enough as gifts be it a coffee mug, T-shirts, wallets, eau de toilette...
