Few facts to consider. First, the dee butter is the most important commodity among nomads. Most of Tibetan nomadic population of high-altitude Plato still live out of Yak herds and caravan trade, not agriculture, unlike fertile western provinces. Second, there is much more influence in traditional households from closely related tribes of neighboring Nepal and Sikkim and Bhutan (Sherpa, Lepcha, Tamang, Bhutia) than from Ladakh or Chinese mainland, so it is more reasonable to think of Nepalese/Indian influence. Third, there were more trade and migration with Nepal and North India than China or Kashmir. Some caravan routes ran there, of course, but they were not that busy as those to Kathmandu, Sikkim or Bhutan. You could see that most of heritage buildings in Lhasa has been decorated by Nepalese craftsmen and artists.
