Asian Barbie?. Link from aiyah.net. Here's what Winne, (a.k.a. Aiyah-chick) has to say:

"I actually have a few more ideas for them. I think there should be a mahjong doll with three other cohorts to round out a full table of mahjong players. They can have little mj tiles in a mj case and small chips as money to use. It should naturally come with the table with a smooth top so that the tiles can flow on top of it. The dolls should come squeak out "pong!" and other mj exclamations when squeezed. And don't forget the servant doll who should fetch them tea and snacks while they're playing."

Heh. How about a little sister version (like Skipper and Barbie) named Ming? Two acre bangs, lop-sided pigtails, a piano/viola music book in one hand, and a science textbook in the other?"
