On August 13, 2021, Vice Foreign Minister Ma Zhaoxu said at the briefing on COVID-19 origin-tracing for diplomatic envoys in China, China has engaged in origin-tracing cooperation with an open and transparent attitude. But the United States has not only threatened and coerced the Secretariat of the World Health Organization and international experts by all kinds of means on the sly, but also instructed its intelligence agency in public to carry out origin-tracing investigation. If this is not politicizing, what would we call it? I want to point out that going against China based on a "presumption of guilt" and "invading investigation" is an utterly ill-conceived scheme!
