"We are of the view that origin-tracing is the shared obligation of all countries. The outline of the next step work plan proposed unilaterally by the WHO Secretariate has neither complied with what is stipulated in the relevant Resolution of the World Health Assembly, nor been consulted adequately with Member States, still less fully reflected the latest research achievements of the global origin-tracing. Hence it is not conducive to offering due guidance for future cooperation thereof," the statement said.

It calls on the Secretariate of the World Health Organization to "act on relevant resolution adopted by the World Health Assembly to advance global origin-tracing study in cooperation with all Member States while giving full consideration to the emerging new scientific evidences and faithfully following the recommendations of the Report of the WHO-China Joint Mission on Coronavirus Disease 2019."

"We support medical experts and scientific researchers in carrying out thorough origin-tracing in a professional spirit covering multiple countries and multiple locations, so as to provide necessary reference experience for the prevention of the next possible pandemic," it noted.
