"I concur with the many scientists who say that politicizing the science does not help genuine efforts to identify the origins of SARS-CoV-2, or ongoing collaboration between Chinese and Western scientists," said Hume Field, a science and policy advisor for China and Southeast Asia at EcoHealth Alliance in New York.

It just generates "doubt" and "mistrust" and fundamentally undermines the united global effort needed to prevail against the virus and the pandemic, Field told Xinhua.
