Experts view these energy efficient and sustainable buildings as models for a nation now searching for a road to sustainable development -- and, more importantly, as the focal point for a wider public discussion on the course of China's development.

The public discussion and concern over air quality is not limited to a local or environmental issue, but rather a question of development pattern, said Zheng.
In the past, China put much weight on economic development, and sacrificed rights in other areas. The road of sustainable development reflected a comeback of public awareness that demands attention to the sacrificed interests.

It would be the same in many other areas. Of course, nobody can grow mature overnight, and the Chinese shall learn more and go through more tests. But the Olympics is a good start.
