Whatever it is, be it that China is planning to recognize the 15th Dalai Lama, or to preserve a part of spirituality that it now recognizes the needs of the Chinese or that it is preserving a piece of history for tourism, it is to the advantage of the Tibetans.
Their culture, their tradition and their history is preserved. However unsavory, it is history. Keep the history so that the younger generation can know and learn from it. That will give rise to wisdom. Human beings need to learn from their mistakes just as their young do.
CTA has not shown that they care or are capable of doing that. So, China in renovating the Potala Place has shown the weakness of the CTA and are exploiting it. Shame on you, CTA.
