Lobsang Sangay is telling lies, he will not bring the Dalai Lama back to Tibet. The Dalai Lama has expressed many times that he wants to go back to Tibet but nothing has been done. Lobsang Sangay talks only but never acts on it.
The Dalai Lama is the money making tool for Lobsang Sangay, he will never let the Dalai Lama go back to Tibet. If he let the Dalai Lama go back to Tibet, what will happen to the CTA? It will mean there is no need for the CTA anymore, Lobsang Sangay will lose his job. He is not so stupid to let go of his position as the president of the CTA yet before he has made enough money for himself.
If Lobsang Sangay really wants to bring the Dalai Lama back to Tibet, he will stop condemning China and stop his free Tibet campaign. If the CTA does that, the Chinese government might consider having a dialogue with the CTA to discuss the matter on the returning of the Dalai Lama. But Lobsang Sangay's action clearly shows that he is not going to do that, he is just a big liar!
