A welcome (and concrete) confirmation that development and poverty reduction remain key global priorities!
Thrilling end to a week in Seoul, with $23.7bn in donor contributions raised from a coalition of nations, to help #EndPoverty on a #LivablePlanet. @WBG_IDA will leverage this x4 to deliver $100bn over 3 years for the countries that need it most. #IDAWorks #IDA21

The short answer is that timing is more important than allocation.
