According to the present status of China´ s water resources and the needs of sustainable development, it is imperative and possible to carry out the south-to-north water diversion project, that is to divert water from the Yantze River valley, which has plentiful water resources, upward to the north part of China.

The principle of south-to-north water diversion should be as follows： Establish the sociaty of water-saving, do not supply water according to the “exaggerated needs”； distribute water rationally, and pay attention to tapping the potential; the east and weet water diversion routes are existing side by side and playing a part together, not irreconcilable to each other; make budget estimate in a practical and realistic way, avoiding endless supplementary budgets; the partial and local interests must be subordinated to the interests of the whole, and the temporary interests, subordinated to the long-term enes; implement unified management, scientific allocation and the charginy system for use of water resources; to divert water from the southwest region is not realistic, better to put off.
