But it appears Guterres' warnings went unheeded by many, as Statista's Sarah Feldman notes that as the United Nations concludes its two weeks of annual meetings in New York, some states remain timelier with their annual payments than others.

Seven months later about two thirds of member states have made their payment to the regular budget. All permanent members have made their full regular payments, except the United States.
