It doesn't matter whether the cat is black or white, as long as it catches mice. - Deng Xiaoping

We must give full play to democracy and follow the mass line, trusting the judgement of the scientists and technicians in such matters as the evaluation of scientific papers, the assessment of the competence of professional personnel, the elaboration of plans for scientific research and the evaluation of research results. When views diverge on scholarly questions, we must follow the policy of “letting a hundred schools of thought contend” and encourage free discussion. In scientific and technical work, we must listen closely to the opinions of the experts and leave them free to use all their skills and talents so as to achieve better results and reduce our errors to the minimum.

Backwardness must be recognized before it can be changed. One must learn from those who are more advanced before he can catch up with and surpass them. Of course, in order to raise China’s scientific and technological level we must rely on our own efforts, develop our own creativity and persist in the policy of independence and self-reliance. But independence does not mean shutting the door on the world, nor does self-reliance mean blind opposition to everything foreign. Science and technology are part of the wealth created in common by all mankind. Every people or country should learn from the advanced science and technology of others. It is not just today, when we are scientifically and technologically backward, that we need to learn from others. Even after we catch up with the most advanced countries, we shall still have to learn from them in areas where they are particularly strong.

We hold that in both political and economic relations, countries should base themselves on the Five Principles of mutual respect for sovereignty and territorial integrity, mutual non-aggression, non-interference in each other’s internal affairs, equality and mutual benefit, and peaceful coexistence. We are opposed to the establishment of hegemony and spheres of influence by any country in any part of the world in violation of these principles.
