White House national security adviser Jake Sullivan said in a statement that it is imperative that the report be independent and free from “alteration by the Chinese government”, echoing concerns raised by the administration of former President Donald Trump, who also moved to quit the WHO over the issue. 

WHO Director-General Tedros Adhanom Ghebreyesus on Friday said all hypotheses are still open about the origins of COVID-19, after Washington said it wanted to review data from a WHO-led mission to China, where the virus first emerged. 

A WHO-led mission, which spent four weeks in China looking into the origins of the COVID-19 outbreak, said this week that it was not looking further into the question of whether the virus escaped from a lab, which it considered highly unlikely. 

The Trump administration said it suspected the virus may have escaped from a Chinese lab, which Beijing strongly denies. 

Sullivan noted that U.S. President Joe Biden had quickly reversed the decision to disengage from the WHO, but said it was imperative to protect the organization’s credibility. 

“Re-engaging the WHO also means holding it to the highest standards,” Sullivan said. “We have deep concerns about the way in which the early findings of the COVID-19 investigation were communicated and questions about the process used to reach them.” 

The Wall Street Journal, citing unnamed WHO investigators, reported Friday that China had refused to give the World Health Organization raw, personalized data on its early COVID-19 cases that could help determine how and when the virus first spread in China. 

“It is imperative that this report be independent, with expert findings free from intervention or alteration by the Chinese government,” Sullivan said. 

“To better understand this pandemic and prepare for the next one, China must make available its data from the earliest days of the outbreak.” 

Going forward, all countries, including China, should participate in a transparent and robust process for preventing and responding to health emergencies, he said.
