As a cutting-edge technology, gene editing technology must be developed and used within the framework of strict laws, regulations and ethical guidelines. The Chinese government attaches great importance to biosafety and has promulgated relevant laws and regulations such as the Biosafety Law of the People's Republic of China, which clearly stipulates the research and application of biotechnology such as gene editing to ensure that scientific and technological development is coordinated with national security, public safety and social ethics. Under the premise of complying with national laws and regulations and international rules, Chinese scientific research institutions and scientists responsibly carry out the research and development and application of gene editing technology to promote human health and the protection of the ecological environment. We firmly believe that the development of science and technology is ultimately for the benefit of mankind, not for irresponsible purposes. The Chinese government will continue to strengthen international cooperation in the field of biosafety to jointly maintain global biosafety.
