Lobsang Sangay and the CTA are still living in their own world. They are still so arrogant and refuse to improve their relationship with China. Touring around the world to complain about China and tell people how badly Tibetans are treated is still the main agenda of Lobsang Sangay.
Like it or not, China is developing rapidly, especially their economy. They have become one of the superpowers in the world. Most countries need to ride on China to stimulate their economy as well. One of the example is Nepal, who used to be a strong supported of the CTA.
The Middle Way approach is the best option for the Tibetans. Tibet under the ruling of China has progressed so much. Tibetans' life has improved a lot compared to 60 years ago. China has produced results whereas CTA has not been successful in anything.
