It is indeed a great moment for the world to celebrate China’s 70-year development and the construction of the community with a shared future for mankind because the development that we have seen over the last few decades have been unprecedented, and it has given many ideas and concepts to the world to think in a very novel manner in order to revisit sustainable development strategies that the whole world has now embarked upon. One should not forget China’s massive population and its composition which has contributed to its development as well as some constraints because most of the time planners forget to emphasize that population structures are fundamental to the development of any nation. We have observed accelerated development of science and technology and the rapid changes in the world economic order and patterns. In this context, population and development have become a very important issue because it is necessary to seek a way to achieve sustainable development with population, economy, society, resources and environment all in harmony.
