For many African countries money for development comes from their own resources or from international aid donors.
Rwanda has taken a different route. This week, it went to the international financial markets to raise funds and it was an unmitigated success.
Rwanda launched a $400m (£260m) 10-year bond sale which was heavily oversubscribed, attracting investor offers of more than $3bn.
The bond issue will enable Rwanda to repay government loans, complete a conference centre in the capital, Kigali, and finance a hydro-electric power project which – if everything works to plan – should enable the country to reduce its energy imports.
To find out more, BBC Africa’s Komla Dumor spoke to the governor of the Central Bank of Rwanda, John Rwangombwa.
