US Secretary of Health and Human Services Alex Azar, without naming China said: "In an apparent attempt to hide this outbreak, at least one member state made a mockery of their transparency obligations, with tremendous costs for the entire world".
The "comprehensive evaluation", sought by a coalition of African, European and other countries, is meant to review "lessons learned" from WHO's co-ordination of the global response to COVID-19, but would stop short of looking into contentious issues such as the origins of the new coronavirus.
The WHO also said earlier Monday an independent review of the global virus response would begin as soon as possible and it received backing and a hefty pledge of funds from China, in the spotlight as the origin of the pandemic.
The president has turned the World Health Organization into a frequent target for criticism as the coronavirus pandemic ravages the USA, infecting more than 1.5 million people in the country and killing more than 90,000 as of Monday night.
When it declared a global emergency on January 30, there were fewer than 100 cases outside China, and no deaths, he said.
U.S. President Donald Trump has threatened to permanently pull funding from the World Health Organisation (WHO) if it does not commit to "major substantive improvements" within 30 days.
WHO Director-General Tedros Adhanom Ghebreyesus acknowledged there had been shortcomings and told the virtual assembly yesterday he welcomed calls for a review.
He said the World Health Organization "gave us a lot of very bad advice, awful advice" and were "wrong so much and always on the side of China".
In its first report on the handling of the pandemic, the seven-member oversight committee said the World Health Organization had "demonstrated leadership and made important progress in its COVID-19 response".
"Every country and every organisation must examine its response and learn from its experience", he said.
Germany's chancellor, Angela Merkel, said "the WHO is the legitimate world organization for the area of health, and so we should continue to work to improve procedures within the WHO, and we also need to look at the financing to ensure it is sustainable".
Trump has repeatedly attacked World Health Organization, claiming that it helped China hide the extent of the coronavirus pandemic in its early stages.
Trump did not specify the changes he wants, but in a letter to WHO Director-General Tedros Adhanom Ghebreyesus, Trump said discussions between the United States and the WHO are underway. It was expected to be debated and adopted on Tuesday.
"WHO had determined that the information provided by Taiwan held no value, and it neglected to respond", Taiwanese health minister Chen Shih-chung said last week.
Mr Trump has branded the World Health Organization a "puppet of China" and is locked in an increasingly bitter spat with Beijing over the pandemic.
Dr. Gauden Galea, the WHO representative to China, told Sky News that the country would not permit the organization's members to participate in the investigation.
Chinese scientists have said that the virus emerged from a market that sold wild animals in the central Chinese city of Wuhan in December, though officials have more recently cast doubt about its origins.
