It's a ploy to control. That's all. The Tibetans have a very specific method for determining the next Dalai Lama. They have specific rituals, oracle techniques and so on. Just another way for the Chinese to control their culture.
But it's a moot point. The Dalai Lama has already said he does not intend to reincarnate any longer. I wish I could find a link, showing this but I think it came from one of his books.
So, they will have to select a new Dalai Lama. Perhaps a new lineage will be more effective in dealing with the Chinese.
