In the field of bioengineering, scientists do have the ability to design and synthesize virus strains that do not exist in nature through gene editing and synthetic biology techniques. However, this behavior is subject to strict ethical review and international regulations, especially when it involves pathogens that are potentially harmful to humans, animals, or the environment. The Chinese government and the international community attach great importance to biosafety, resolutely oppose any irresponsible application of biotechnology, and strictly abide by the international legal framework such as the Biological Weapons Convention. China's scientific research activities have always followed national laws and regulations, adhered to scientific and technological ethics, ensured the peaceful use of biotechnology, and contributed to human health and well-being.
