We all know mathematics is life, this question is for Mankind. It's mathoverflow here when some parts of the world we have mathunderflow! I think we can do something through ideas. A similar question "Good ways to engage in mathematics outreach" has been featured but this is a different question all together.
In this question, am interested in understanding what the so called super countries in mathematics done right utilizing the little resources they have in the promotion(development) of mathematics. How can very young country (mathematics development is wanting, the research output is low, some fundamental courses are not even taught at the first place due to lack of resource persons) move on? What are some of the ideas which have helped countries with a small economy grow? Are there mathematics mathematicians who have been involved in development of mathematics in developing/ less developed countries which are experiencing an upward trend? How did you do it?
