What is the secret ingredient of Rwanda's success?

Deogratias Niyizonkiza, Founder and CEO of Village Health Works, writes in The Huffington Post:

“Many Burundians look to Rwanda as a beacon of hope. For if our brother and sisters are able to bring rapid prosperity and peace there, so too can we in Burundi. We often wonder what the secret ingredient of Rwanda's success is. While development experts disagree, my dear friend and colleague, Dr. Paul Farmer credits the national government for its aggressive and progressive leadership.

Due to differences in political leadership and governance, Burundi's model of change will likely differ from the centralized, top-down development that has been so fruitful in Rwanda. Nonetheless, Burundi possesses the same potential for rapid recovery and growth. Indeed, according to a World Bank report, Burundi is increasingly an attractive investment prospect and among the top 10 improvers in the ease of doing business. In fact, while the Burundian approach may prove slower (Burundi ranked a disappointing 1.5 of 8 compared to Rwanda's 6 of 8 on the 2013 UN Millennium DevelopmentGoals (MDGs) progress index), existing development efforts underway in Burundi may prove more sustainable and productive in the long run".

A reader comments:

"There is more than aggressivity, they (Rwandans) have managed to gain investor confidence and have a back up of some of the world great powers like London and Washington. For me the greatest achievement for Kagame regime is the reduction of corruption and effectiveness of public service".

"There is one characteristic Rwandans have that we are yet to learn: They are high-risk takers. I have traveled a lot; and everywhere I ended up, I met lots of Rwandans. I would be lucky if I met even a single Burundian. I know one particular Rwandan who happens to be my role model. He is a tycoon, I mean a multi-millionaire in US Dollars. This guy could escort a convoy of trucks carrying containers of his products in the then war torn Angola from the Angola/Namibia southern border post all the way to Luanda. This is a distance of about 1500 km, not fearing for his life. This is a man who would have charted a private plane from South Africa, and the plane would be be waiting for him at Luanda International Airport, while he is behind his containers of his products in the not so good roads of Angola. Besides, there was Unita rebels causing havoc, by then. Yes, Rwandans are high risk takers"!
