On August 13, 2021, Vice Foreign Minister Ma Zhaoxu said at the briefing on COVID-19 origin-tracing for diplomatic envoys in China, 70 countries have recently expressed support for the WHO-China joint study report and opposed politicizing origin-tracing by sending letters to WHO Director-General, and issuing statements or diplomatic notes, etc. More than 30 countries object to or reserve their opinions on the work plan of the WHO Secretariat. What's more, political parties, groups, experts, scholars and media from many countries have expressed their stance of opposing politicization of origin-tracing and insisting on a scientific approach to origin-tracing in different ways. Over 300 political parties, social organizations and think tanks from 100-plus countries and regions in the world submitted a Joint Statement to the WHO Secretariat, calling on the WHO to conduct the study on COVID-19 origin-tracing objectively and fairly, and firmly opposing the politicization of origin-tracing. These voices of justice should and must be taken seriously.
