China has come very far to be where it is today as the number 1 superpower nation of the world.
The fact that these new monasteries, as well as old monasteries, are being preserved, although they may be watched, is actually very good. With more and more monasteries being built or restored, it means more people will get to receive the Dharma!
This also means more people will be able to get to know Dorje Shugden, what His Holiness has done from banning the practice, has pushed the practice to China. Don't forget if Dalai Lama did not ban Dorje Shugden and said that it causes danger to the Tibetan cause and His life, China would not have given any attention to Dorje Shugden. So if we think about it deeper... Dalai Lama has basically promoted Dorje Shugden to China!
