Beijing, June 29 (TIWN) The Chief of Lancet Covid-19 Commission has dismissed claims by the Chinese government that he is being pushed by the US government to favour the Wuhan lab-leak theory, the media reported on Tuesday.

There is "no outside interference whatsoever", Jeffrey Sachs, a professor of economics at Columbia University in New York, was quoted as saying by the South China Morning Post.  Sachs is also the chair of the interdisciplinary initiative backed by medical journal The Lancet to find solutions to the pandemic.  His comment follows an accusation by Chinese Foreign Ministry spokesman Wang Wenbin on Monday that "some international scientists on Covid-19 origin studies, including US members of the Lancet Covid-19 Commission, were threatened, cyber attacked and forced by some US politic to give up the widely proven natural origins hypothesis and turn to the lab-leak theory", The Global Times reported.
