Some of my mom's Chinese teapots have that pattern...
Yup, quite a lot of Tibetan designs, etc. have Chinese influence. Most have a distinctly Tibetan flavor to them while retaining Chinese characteristics, while some are wholly Chinese. Also, in the old days, a lot of top quality traditional Chinese stuff (handicrafts, pottery, silk, etc.) were highly valued in the Tibetan and Himalayan areas, they still are.
