From Qinghai with love - ecology before GDP

Qinghai province, which shares the roof of the world with Tibet, had a special gift for China on the occasion of the World Environment Day On Friday - a fresh approach toward ecological conservation in the region.

The Qinghai Academy of Social Sciences released a book titled The Studies on the Ecological Values of China's Sanjiangyuan and its Compensation Mechanism to mark the occasion.

In his preface to the book, Qiang Wei, the Party chief of Qinghai, says maintaining a basin of clear water at Sanjiangyuan, the source of Yangtze, Yellow and Lancang rivers is a "compelling obligation".
