French President Emmanuel Macron called on Monday for the World Health Organization (WHO) to be empowered to visit countries rapidly in case of outbreaks with potential to spark a pandemic, and to access data.

Macron and German Chancellor Angela Merkel, in separate pre-recorded remarks to the WHO’s annual ministerial assembly, called for the U.N. agency’s funding to be improved and backed the idea of a new international treaty to prevent pandemics.
