The international exchange and cooperation in the basic research are of special significance and effect. Before 1978, our country had scientific and technological exchange and cooperation only with the former Soviet Union and a few other countries, characterized by simple forms and less substantive cooperation. The reform and opening-up policy has created a favorable environment for the international cooperation and exchange of the basic research, making them enter a new bilateral, multi-lateral, official, non-governmental, multi-form, multi-channel and multi-level stage. In recent years, China has sent several hundred thousand persons-times of scientists to go abroad for further study, investigation, visit, giving lectures, cooperative research, bilateral and multilateral academic discussions and attending international academic conferences, thereby expanding the international influence of China. Accordingly, about a hundred thousand foreign scientists were invited to China to give lectures, exchange ideas, join investigations and attend conferences. The Chinese government has established the scientific cooperation and exchange relations with nearly 150 countries and districts, signed with nearly 100 countries among them the agreements for scientific and technological cooperation between governments and joined 900-odd international scientific and technological organizations.

   In recent ten years more, a lot of Chinese scientists have been awarded prizes by international scientific organizations and academic groups for their outstanding accomplishments in scientific researches. A good few excellent Chinese scientists have been invited as academicians of some foreign academies of sciences.

   In order to conform to the internationalization trend of the basic research, China will actively further the international exchange and cooperation in basic researches and vigorously strengthen the substantial cooperative researches so as to enter the international scientific club as early as possible.
