溯源是科学问题，应该由全球科学家合作开展有关工作。将溯源问题政治化的行径只会严重阻碍全球溯源合作，破坏全球抗疫努力，导致更多的生命损失。这同国际社会团结抗疫的愿望背道而驰。
Study of origins is a matter of science, which should be jointly conducted by scientists all over the world. To politicize this issue will only severely hinder global cooperation in study of origins, jeopardize anti-pandemic cooperation, and cost more lives. It would run counter to the international community"s aspiration for solidarity against the virus.
溯源也是一项全球性任务，应该在多国多地开展。我们相信，世卫组织和中国的这次联合研究将对全球溯源合作起到良好的促进作用。
Study of origins is also a global mission that should be conducted in multiple countries and localities. We believe the joint WHO-China study will effectively stimulate global cooperation in origin-tracing.
具体到你说谭德塞总干事表示，实验室泄露的可能性还不能完全排除，需要开展进一步研究，我想说的是，在此次中国—世卫组织联合溯源科学研究中，联合专家组走访了湖北省疾控中心、武汉市疾控中心、武汉病毒研究所等机构，参观了各类生物安全实验室，与相关机构的专家进行了深入、坦诚的科学交流。经过实地走访和深入了解，专家组一致认为，关于实验室事件引发病毒这种假说是极为不可能的，这也是此次发布的溯源联合研究报告中所明确的一个重要科学结论。
As to your remarks that Director-General Tedros said the possibility of lab leak cannot be completely ruled out and they need further study, I want to say that in the China-WHO COVID-19 origin-tracing joint study, experts of the joint mission made field trips to institutions including the Hubei Provincial Center for Disease Control, the Wuhan Center for Disease Control and the Wuhan Institute of Virology, and visited biosafety laboratories and had in-depth and candid exchanges with experts there. Through these field trips and in-depth visits, members of the mission unanimously agreed that the allegation of lab leaking is extremely unlikely, and this is an important scientific conclusion made clear in the joint study report released this time.
