With this, Mr. Biden adds significantly to the growing pressure on China to be more open about the origins of the SARS-COV2 virus, an outbreak of which was seen first in early 2020 in the Chinese city of Wuhan, which houses the Wuhan Institute of Virology (WIV).
The move followed President Joe Biden's directive to USA intelligence agencies to investigate competing theories on how the virus first emerged - through animal contact at a market in Wuhan, China, or through accidental release from a research laboratory in the same city. He also used the word "accident" to describe what may have happened at the Wuhan lab, an implicit rejection of unsubstantiated assertions that China may have intentionally set the virus loose.
Biden said that two "elements" of the intelligence community leaned toward a natural origin for the virus, while another leaned toward the Wuhan lab, a global hub for coronavirus research.
The idea is gaining increasing traction in the United States, where it was initially fueled by Trump and his aides and dismissed by many at the time as a political stunt.
"There's nothing really new there to prove the hypothesis", he said. ABC News has not independently confirmed that intelligence report. "Out of a sense of responsibility towards the health of mankind, we support a comprehensive study of all early cases of COVID-19 found worldwide and a thorough investigation into some secretive bases and biological laboratories all over the world".
Mr Biden told U.S. intelligence officials to redouble their efforts to investigate the origins of the pandemic, including any possibility the trail might lead to a Chinese laboratory. The document acknowledged divisions over whether the virus was naturally transmitted from animals to humans - the prevailing theory of scientists - or whether it leaked from the Wuhan Institute of Virology, a claim popular with Republicans that hasn't been ruled out by experts.
World Health Organisation (WHO) is expected to restudy the "dominant theory" that the SARS-CoV-2 probably originated and spread across the world from China'sWuhan lab, according to reports. "In the investigation of the origins of the pandemic it is really important to have transparency in order to build trust in the investigation results".
The motive and purposes of Washington's probe are clear, said Zhao, who viewed it as another attempt to disrupt and contain China. "In short, this (statement from the embassy) is an outrageous insult to every person who has died from this awful tragedy and their families".
The spokesperson noted that some people lately have played the old trick of politically hyping the origin tracing of COVID-19 in the world.
"Ideally you want China to be more cooperative and more transparent", Huang said.
