In this regard,on June 24,the Standing Committee of National People's Congress deliberated the draft of Energy Saving Law,according to which China is to take"resources saving"as a basic national policy.This is a key issue to the long-term benefits of China.With relevant questions,China's Foreign Trade interviewed Dr, Yonglong L(?),Secretary-general,Chinese Committee for SCOPE(Scientific Committee on Problems of the Environment/ICSU).and Research Professor at the Chinese Academy of Sciences.
