Well, not in China. iQue's website only lists a handful of major titles that are mostly, if not all, made by Nintendo, including the two aforementioned 3DS titles and six DS titles (Nintendogs, WarioWare, Yoshi's Island DS and more), along with several downloadable DSiWare apps.
Nintendo's already dipped its toes into motion-sensing handheld gaming with the gyro-equipped WarioWare: Twisted for the Game Boy Advance, but it looks like the company looks has even grander plans to let you make a fool of yourself in public, at least if a recent patent application is any indication.
