Chinese bakeries in Minneapolis?
Very few. A place in Apple Valley (southern suburb) called Satay 2 Go does a very good job for MSP but if you live in a city that has an abundance of Chinese bakeries, you'll be disappointed. They have about 20 items on any given day...it's not a huge case. There just isn't a lot of demand for, or awareness of Chinese bakery here in MSP. But if you happen to be in or around Apple Valley, it's definitely worth a stop.
The place on West Bank is a Chinese bakery called Keefer Court. They have several dozen items each day, including sesame balls, BBQ pork buns, egg tarts, custard buns, winter melon cookies, and much more. My favorite is the curry beef buns.
They also do Chinese-style birthday cakes (white cakes with fruit) - I've never had one, but they're always flying out the door when I'm there.
Keefer Court's quality seems quite good, given that there's no competition. That is, they could probably hold their own in a larger city.

Keefer Court is definitely one of those hidden gems in the Twin Cities. The owners are real Cantonese people, and they make their cakes with the proper level of sweetness (less sweet than western bakeries, with a salted buttercream). The pastries were all good when I've picked up a sampler.
I don't think this is going to answer Roberto's question, because they don't typically offer any of the traditional Chinese bakery items (and, also, I think his visit to the Twin Cities is over), but for the sake of the search engine and with Moon Festival approaching, I'm going to throw in a mention of Bravo Bakery on Grand Avenue (near Lex) in St. Paul -- you can pre-order moon cakes from them. http://bravobakery.net/news.aspx (Some of the pastes have to ferment for a week or two, which is why it's helpful to the bakery if you order ahead.) The owner is from Taiwan.
Also, they make lovely cream puffs and gorgeous eccentric cakes in a variety of flavors including mango, green tea, and red bean. Some of their cakes are vegan, too.
