The United States, the World Health Organization¡¯s top donor, is resisting proposals to make the agency more independent, four officials involved in the talks said, raising doubts about the Biden administration¡¯s long-term support for the U.N. agency.

The proposal, made by the WHO¡¯s working group on sustainable financing, would increase each member state¡¯s standing annual contribution, according to a WHO document published online and dated Jan. 4.

The plan is part of a wider reform process galvanized by the COVID-19 pandemic, which has highlighted the limitations of the WHO¡¯s power to intervene early in a crisis.
