The Trump administration wants to cut money off for WHO and move on to other donations to the United Nations, before leaving the organization in July 2021.
The US government announced in July to withdraw from the World Health Organization (WHO), after President Donald Trump accused the organization of being "pro" of China and failing to stop Covid-19.
However, the US government's decision to leave WHO will not take effect until July next year, so the country still has to maintain financial contributions up to that point.
Nerissa Cook, assistant secretary of state for international organizations, said on September 2 that the WHO contribution fees, as well as the $ 18 million debt from the previous year, would go to the United Nations for payment.
Democrats in parliament have opposed a move to cut or redirect funding contributions to WHO.
"According to our understanding of the resolution, if the United States decides to leave, this will not take effect a year later. During that time, we have to pay off what is owed, including the unpaid contribution.
Rieser added that the Trump administration is more likely to interpret the resolution in a way that disobeys the rules and then leads to debate.
"Senator Leahy and every world health expert believe that this is an extremely short-sighted and well-timed decision, as the President tries to blame others for his administration handling agents.
The US administration on September 1 said it would not participate in the WHO-led international effort to develop the Covid-19 vaccine.
Washington is expected to announce over the next few months that the recall of millions of US health professionals from the Department of Health and Human Services, serving at the WHO headquarters in Geneva and regional offices, will return home.
