Bhutia looks at the conflicting claims of India and China about the history and status of this small community, who were largely traders in Lhasa until they left in 1961. In Kashmir, they are Indian nationals - but not state subjects. That's limits their opportunities for employment or owning land and it perpetuates an ambiguity about who they are.
By coincidence, the same community was earlier this year the subject of a blog post by Andrew Whitehead ... http://www.andrewwhitehead.net/blog/a-week-in-kashmir-the-tibetan-colony ... the image below, taken in the Tibetan colony in Srinagar, is from that post.
